Description

Packaged antenna device and terminal equipment

Technical Field

The present application relates to the field of communications technologies, and in particular, to a packaged antenna apparatus and a terminal device.

Background

The transmission and reception of signals in wireless communication require an antenna for transmission and reception, and as shown in fig. 1(a), the antenna basically comprises a reflection plate 2 (which is also a signal reference ground), a radiator 3, a feeder 1 (for connecting radio frequency signals to the antenna), a director 4, and the like. The main indexes of the antenna include bandwidth, gain, polarization mode and the like. The wider the bandwidth, the more the antenna can support the working frequency bands, thereby supporting the transmission with higher channel capacity; higher gain represents higher energy emitted by the antenna and may support greater communication distances. In addition to the above-described structure, the antenna may be provided with a parasitic antenna for increasing the bandwidth of the antenna, or with a director for raising the gain of the antenna.

In 5G millimeter wave communication, because the wavelength is shorter, the Antenna size can be made very small, so in recent years, the millimeter wave Antenna is generally designed as AOB (Antenna on board) or AIP (Antenna in package), and compared with AOB, the radio frequency lead of AIP is shorter, so the feed loss is smaller, and because the Antenna is directly designed on the package, the whole Antenna is more compact, and the system integration level is higher. As shown in fig. 1(b), a schematic diagram of a conventional AIP is shown, in which there are two radiation modes, namely, a Broadside radiation antenna 5 and an end-fire radiation antenna 6. As shown in fig. 1b, the broadside radiation radiates perpendicular to the AIP upper surface, while the endfire radiation radiates perpendicular to the AIP lateral side. Each radiation mode of operation should strictly speaking be dual polarized radiation. For the Endfire radiation, dual polarization refers to both horizontal and vertical polarization.

However, the conventional dual-polarized AIP research is focused on the design of a Broadside packaged antenna device, and the end-fire dual-polarized AIP research is relatively rare. The horizontal polarization antenna and the vertical polarization antenna of the prior art endfire antenna are still respectively arranged on the ground, which causes the structure of the endfire antenna to be more complicated.

The rf processing chip 310 may feed the edge-fire antenna 320 through a feeding path provided in the substrate 400, so that the edge-fire antenna 320 is excited to receive and transmit an electromagnetic wave signal.

With continued reference to fig. 3(a), the packaged antenna device provided by the embodiment of the present application further includes an end-fire antenna, which includes a horizontally polarized antenna and a vertically polarized antenna. The vertical polarization antenna includes a first radiator portion 330 and a second radiator portion 340, and the first radiator portion 330 and the second radiator portion 340 are stacked along a normal direction of the rf processing chip 310. The first radiator portion 330 and the second radiator portion 340 may be plate-shaped structures with the same size, for example, the lengths H of the first radiator portion 330 and the second radiator portion 340 may be quarter waveguide wavelengths corresponding to an operating frequency band of the vertically polarized antenna, where the waveguide wavelengths are wavelengths when electromagnetic waves propagate in the substrate 400. The sizes of the first radiator portion 330 and the second radiator portion 340 are merely an example, and the sizes and shapes of the first radiator portion 330 and the second radiator portion 340 may also take other forms. With continued reference to fig. 3(a), the first radiator portion 330 and the second radiator portion 340 are connected by a ground plate 390, wherein the ground plate 390 includes a plurality of metal layers 391 and vias 392 connecting the plurality of metal layers 391. The first radiator portion 330, the second radiator portion 340 and the ground layer 390 constitute a radiation structure of the vertical polarization antenna, and in this application, the radiation structure of the vertical polarization antenna is not limited to the above-mentioned components, and may include other structures capable of radiating signals.

With continued reference to fig. 3(a), the vertically polarized antenna further includes a first feed path 360, the first feed path 360 is used for feeding the first radiator portion 330 and the second radiator portion 340, the first feed path 360 is connected with the rf processing chip 310 and is used for coupling the signal emitted by the rf processing chip 310 to the first radiator portion 330 and the second radiator portion 340, as shown in fig. 3(a), the first feed path 360 passes through an opening of the ground plate 390, and the first feed path is electrically isolated from the ground plate 390 at a position of the opening passing through the ground plate 390. As shown in fig. 3(a), the first feeding path 360 includes a feeding line 361 connected to the rf processing chip 310, and a feeding column 363 connected to the feeding line 361, where the feeding column 363 is a column structure formed by a plurality of metal layers and vias connecting the plurality of metal layers. As shown in fig. 3(b), fig. 3(b) is a cross-sectional view of the packaged antenna device taken along a cross-sectional plane perpendicular to fig. 3(a), the number of the feeding posts 363 is two, and the two feeding posts 363 are symmetrically arranged on both sides of the feeding line 361. The ground plate 390 is provided with a second slot 393 matched with the feeding posts 363, the second slot 393 spans the two feeding posts 363, and as shown in fig. 3(b), the length d1 of the second slot 393 is larger than the distance d2 between the two feeding posts 363. When the packaged antenna device is in operation, the two feed columns 363 in the first feed path 360 are coupled to the second slot 393 in the ground plane 390, and a current is excited in the ground plane 390 through the second slot 393, so that currents in opposite directions are generated on the first radiator portion 330 and the second radiator portion 340, and a vertical electric field is generated between the first radiator portion 330 and the second radiator portion 340, thereby forming a vertically polarized electromagnetic wave that radiates outwards. Meanwhile, the two feed columns 363 feed simultaneously, so that impedance matching of vertical polarization can be improved, the purpose of bandwidth improvement is achieved, and the performance of the vertical polarization antenna is improved.

With continued reference to fig. 3(a), the horizontally polarized antenna of the endfire antenna includes a third radiator portion 380 disposed within the substrate 400 and a second feed path 362, the second feed path 362 being connected to the rf processing chip 310 and being configured to couple feed to the third radiator portion 380. The third radiator portion 380 may be spaced apart from the first radiator portion 330 by a quarter of a waveguide wavelength; in the vertical direction, the third radiator portion 380 and the first radiator portion 330 may be disposed in the same layer or in different layers. The first radiator portion 330 is connected to the ground plate 390, and the first radiator portion 330 and the ground plate 390 have the same potential, so that the first radiator portion 330 can serve as both a radiation structure of the vertically polarized antenna and a ground of the horizontally polarized antenna, at the same time. The first radiator portion 330 is used as a ground of the horizontally polarized antenna when the horizontally polarized antenna is provided, and an additional ground (a ground corresponding to the horizontally polarized antenna) is not required. So that the structure of the entire packaged antenna can be simplified.

With continued reference to fig. 3(a), the horizontally polarized antenna further includes a horizontally polarized director 381 disposed within the substrate 400 and cooperating with the third radiator portion 380, and the gain of the horizontally polarized antenna may be increased by the horizontally polarized director 381.

Referring to fig. 3(a) and 3(b), the two feeding columns 363 in the first feeding path 360 are symmetrically disposed on both sides of the feeding line 361, and the current on the feeding line 361 generates horizontal currents with opposite directions (as shown by arrows a and b in fig. 3 (b)) in the process of passing through the feeding columns 363, and the current is coupled to the third radiator portion 380 because the feeding line 361 is close to the third radiator portion 380. However, the currents a and b coupled to the third radiator portion 380 cancel each other out and do not affect the horizontally polarized antenna, thereby enhancing the port isolation between the vertically polarized antenna and the horizontally polarized antenna.

The embodiment of the present application as shown in fig. 4(a) provides a cross-sectional view of still another packaged antenna device, and the reference numerals of fig. 4(a) may refer to fig. 3(a), and unlike fig. 3(a), the bottom end of the feed column 363 of the first feed path 360 is close to the second radiator portion 340. Referring also to fig. 4(b), fig. 4(b) is a cross-sectional view of the packaged antenna device taken along a cross-section perpendicular to fig. 4 (a). When the packaged antenna device is used, the two feed columns 363 in the first feed path 360 are coupled to the second radiator portion 340, so that a current is excited in the second radiator portion 340, and the current flows to the first radiator portion 330 through the ground plate 390, so that currents in opposite directions are generated on the first radiator portion 330 and the second radiator portion 340, an electric field in a vertical direction is generated between the first radiator portion 330 and the second radiator portion 340, and a vertically polarized electromagnetic wave radiating outward is formed. In the present application, two feed studs 363 may be coupled to the first radiator portion 330 at the top end, and the principle of the coupling between the feed studs 363 and the second radiator portion 340 is the same as that described above. Meanwhile, the two feed columns 363 feed simultaneously, so that impedance matching of vertical polarization can be improved, and the purpose of improving bandwidth is achieved, and the performance of the vertical polarization antenna is improved.

Fig. 5(a) shows a structure of a packaged antenna device according to an embodiment of the present application. The third radiator portion 380 of the horizontally polarized antenna includes a positively polarized element 3802 and a negatively polarized element 3801. With continued reference to fig. 5(a), the first radiator portion 330 is provided with a first slot 3301, the positive polarized vibrator 3802 and the negative polarized vibrator 3801 are respectively connected with two opposite side walls of the first slot 3301 in a one-to-one correspondence, and the positive polarized vibrator 3802 and the negative polarized vibrator 3801 are located outside the first radiator portion 330. The vertical projection of the positive polarized element 3802 and the negative polarized element 3801 on the first plane is outside the vertical projection of the first radiator portion 330 on the first plane, which is the installation plane of the first radiator portion 330. The positive polarized element 3802 and the negative polarized element 3801 are spaced apart from the ground (the first radiator portion 330) by a quarter waveguide wavelength, so that the horizontally polarized antenna obtains a superior radiation characteristic.

The second feed path 362 as shown in fig. 5(a) is located above the first radiator portion 330 (with the placement direction of the packaged antenna device in fig. 5(a) as a reference direction), and the second feed path 362 is coupled to the first slot 3301, and the end of the second feed path 362 coupled to the first slot 3301 is a fan-shaped structure 3621, which fan-shaped structure 3621 can achieve better impedance matching for the horizontally polarized antenna. When the second feeding path 362 is coupled to the positive polarized oscillator 3802 and the negative polarized oscillator 3801 for feeding, the second feeding path 362 is first coupled to the first slot 3301, and currents having opposite directions are excited in the first slot 3301 and transferred to the positive polarized oscillator 3802 and the negative polarized oscillator 3801, respectively. Meanwhile, the first radiator part 330 serves as a reflective ground of the horizontally polarized antenna, and the use of the first radiator part 330 as a ground of the horizontally polarized antenna can suppress backward radiation of the horizontally polarized antenna, thereby improving gain of horizontal polarization.

Referring to fig. 5(b) together, the same reference numerals in fig. 5(b) may refer to fig. 4(a) and 5 (a). The horizontally polarized antenna further includes a horizontally polarized director 381 disposed within the substrate 400 and cooperating with the third radiator portion 380, and the gain of the horizontally polarized antenna can be improved by the horizontally polarized director 381.

In order to facilitate understanding of the packaged antenna device provided in the embodiments of the present application, a simulation is performed by taking the packaged antenna device shown in fig. 5(a) as an example, and the simulation result is shown in fig. 6, where the ordinate is amplitude (unit dB), the abscissa is frequency (unit GHz), a curve S1 in fig. 6, 1 is the reflection coefficient of the vertically polarized antenna, S2,2 is the reflection coefficient of the horizontally polarized antenna, and S1,2 is the port isolation between the vertically polarized antenna and the horizontally polarized antenna. As can be seen from fig. 6, the reflection coefficients of both the vertically polarized antenna and the horizontally polarized antenna are less than-10 (dB) level over a very wide bandwidth (covering 24-30 GHz). In addition, the isolation of the horizontal polarization antenna and the vertical polarization antenna exceeds 25(dB) in the whole frequency band, and very good antenna performance is obtained.

As shown in fig. 7(a), in yet another more specific packaged antenna device, the endfire antenna further comprises a horizontally polarized antenna including a third radiator portion 380 and a second feed path 362 disposed within the substrate 400. Referring to fig. 7(a) and 7(b) together, the third radiator portion 380 includes a positive polarized element 3802 and a negative polarized element 3801 that are stacked, and the positive polarized element 3802 is located above the negative polarized element 3801 (the placement direction of the packaged antenna device shown in fig. 7(b) is taken as a reference direction). The positive polarized element 3802 is connected to the second feed path 362 and the negative polarized element 3801 is connected to the first radiator portion 330. In use, current in the second feed path 362 flows to the positive polarised element 3802 and the second feed path 362 excites a reverse current at ground (the first radiator portion 330). With continued reference to fig. 7(b), the horizontally polarized antenna further includes a horizontally polarized director 381 disposed within the substrate 400 and cooperating with the third radiator portion 380, and the gain of the horizontally polarized antenna can be improved by the horizontally polarized director 381.

As shown in fig. 8(a), the packaged antenna device further includes a horizontally polarized antenna, the second feeding path 362 of the horizontally polarized antenna is connected to the rf processing chip, and the second feeding path 362 is connected to the positive polarized element 3802 and the negative polarized element 3801 respectively through a balun structure. One end of the balun structure is connected to the second feeding path 362, and the other end includes a first conductor 3642 and a second conductor 3641, where the first conductor 3642 is connected to the positive polarization oscillator 3802, and the second conductor 3641 is connected to the negative polarization oscillator 3801. Wherein the first electrical conductor 3642 has a current path length less than the current path length of the second electrical conductor 3641.

Fig. 11 is a schematic cross-sectional view illustrating a packaged antenna device 250 according to an embodiment of the present application. The packaged antenna device 250 includes a first substrate 300 and a second substrate 260 disposed opposite to each other. The first substrate 300 may be an interposer (interposer) implemented by using a passive silicon chip; the second substrate 260 may also be an interposer or a printed circuit board implemented by using a copper clad laminate. The first substrate 300 and the second substrate 260 are electrically connected by the BGA balls 312 disposed therebetween. A radio frequency processing chip 310 is disposed on a side of the lower surface of the first substrate 300, i.e., a side of the first substrate 300 facing the second substrate 260, and the radio frequency processing chip 310 is used for processing a radio frequency signal and is electrically connected to the first substrate 300 through a solder ball or other metal soldering material. An edge-emitting antenna 320 is disposed on one side of the upper surface of the first substrate 300, i.e., the side of the first substrate 300 facing away from the second substrate 260, and the maximum radiation direction of the edge-emitting antenna 320 is parallel to the normal of the rf processing chip 310. It should be noted that, in the present application, a direction of the rf processing chip 310 toward the first substrate 300 is defined as a normal direction of the rf processing chip 310, for example, a vertical direction in fig. 11 is a normal direction of the rf processing chip 310. The rf processing chip 310 may feed the edge-radiating antenna 320 through a feeding path provided in the first substrate 300, so that the edge-radiating antenna 320 is excited to receive and transmit an electromagnetic wave signal. The packaged antenna assembly 250 further includes an end-fire antenna having a maximum radiation direction perpendicular to a normal of the rf processing chip 310. The end-fire antenna includes a first radiator portion 330 and a second radiator portion 340 that are oriented in the same direction.

In the packaged antenna device 250, the first radiator portion 330 is disposed in the first substrate 300, the second radiator portion 340 is disposed in the second substrate 260, and the first radiator portion 330 and the second radiator portion 340 are electrically connected through the first metal part 350. Pads may be disposed at one end of the first radiator portion 330 near the second substrate 260 and one end of the second radiator portion 340 near the first substrate 300, so that the connection between the first metal 350 and the first and

second radiator portions

330 and 340 is more stable. The radio frequency processing chip 310 may also feed the first radiator portion 330 through the first feed path 360 disposed in the first substrate 300, so that the first radiator portion 330 and the second radiator portion 340 are excited to receive and transmit electromagnetic wave signals. There is a vertically polarized current in the excited first radiator portion 330, the first metal piece 350, and the second radiator portion 340, which is in a direction parallel to the normal direction of the rf processing chip 310. The above-mentioned antenna polarization modes include horizontal polarization and vertical polarization, and may also include ± 45 ° polarization. For example, when the endfire antenna is excited by vertical polarization or ± 45 ° polarization, a current polarized by ± 45 ° is generated in the endfire antenna.

Since the first metal piece 350 connects the second radiator portion 340 with the first radiator portion 330, the equivalent height of the end-fire antenna is changed from the original height of the first radiator portion 330 to the height of the first radiator portion 330, the first metal piece 350 and the second radiator portion 340. The increase of the equivalent height of the endfire antenna allows the vertical polarization current path generated by the endfire antenna to be distributed over the first radiator portion 330, the first metal 350 and the second radiator portion 340, i.e., the polarization current path of the endfire antenna in the vertical direction is increased, thereby improving the gain and bandwidth of the endfire antenna. It should be noted that the equivalent height of the antenna in this application refers to the height of the end-fire antenna in the vertical direction, i.e. the direction parallel to the normal of the rf processing chip 310.

In an embodiment, the packaged antenna device 250 may further include a chip disposed on a side of the second substrate 250 opposite to the first substrate, where the chip may be a CPU (Central Processing Unit) chip or a cache chip, such as a DRAM (Dynamic Random Access Memory).

The first radiator portion 330 and the second radiator portion 340 may be implemented by a via hole (via) as shown in fig. 11, wherein the first radiator portion 330, the first metal piece 350, and the second radiator portion 340 are located on a straight line. Fig. 12 is a schematic cross-sectional view of another embodiment of the packaged antenna device 250, wherein the same reference numerals in fig. 12 refer to fig. 11. Different from fig. 11, according to the type of the antenna and the wiring requirement, the first radiator portion 330 and the second radiator portion 340 in fig. 12 may also be implemented by via arrays (via arrays) arranged in a staggered manner and interlayer routing (the interlayer routing is used for connecting vias arranged in a staggered manner), that is, the first radiator portion 330 and the second radiator portion 340 are bent, so as to improve the bandwidth of the antenna. Compared with the via holes, the actual equivalent heights achieved by the via hole arrays arranged in a staggered manner and the interlayer routing are the same, and the vertical polarization current paths can be respectively arranged on the first radiator part 330, the first metal piece 350 and the second radiator part 340, so that the gain and the bandwidth of the end fire antenna are improved.
