Definitions
- the present invention relates to an antenna, especially to an eight-frequency band antenna for enhancing the frequency response of the low-frequency segment and bandwidth of the high-frequency segment.
- the current commercially available planar inverted-F antenna is generally formed by printing metal material (such as copper) on printed circuit board (PCB) with two-dimensional printing technology. Alternatively, metal membrane is pressed into three-dimensional multi frequency band antenna.
- the multi frequency bands signal transmission/reception can be achieved by changing the two-dimensional radiation patterns or the geometric shape of the three-dimensional radiation bodies.
- the antenna formed on PCB or formed by pressing metal membrane into radiation body need a specific volume to ensure signal transmission/reception quality and prevent signal tuning problem caused by environment.
- the electronic device needs an internal space for arranging the PIFA structure; this causes impact on light weight and compact requirement of the electronic devices.
- the radiation body of the antenna can be fabricated on a rectangular ceramic carrier.
- the carrier 101 of the antenna 10 has a high-frequency radiator 102 and a low-frequency radiator 103 on the surface thereof and the carrier 101 is fixed on the PCB 20.
- the PCB 20 has a ground metal plane 201, a signal feeding micro strip 202 and a ground wire 203 on two faces thereof, where the signal feeding micro strip 202 connects with the ground wire 203 and the radiator of the carrier 101.
- the high-frequency radiator 102 is arranged on the right side of the carrier 101 and the low-frequency radiator 103 is arranged on the left side of the carrier 101.
- the antenna 10 is electrically connected to the PCB 20 and the area of the ground metal plane 201 corresponding to the low-frequency radiator 103 is smaller than the area of the ground metal plane 201 corresponding to the high-frequency radiator 102. Therefore, the low-frequency radiator 103 suffers more to the ground shielding and the frequency response (see label A in Fig. 2 ) is not satisfactory. Moreover, the bandwidth of the high-frequency radiator 102 is not wide enough (only covering 6 bands as shown by label B in Fig. 2 ). As a result, the signal transmission/reception quality is poor and signal transmission/reception bandwidth is limited.
- WO 2014 058926 A1 discloses an antenna capable of operating among all LTE bands, and also capable of operation among all remote side cellular applications, such as GSM, AMPS, GPRS, CDMA, WCDMA, UMTS, and HSPA among others.
- the antenna provides a low-cost alternative to active-tunable antennas suggested in the prior art for the same multi-platform objective.
- US 8 779 988 B2 discloses a surface mount device multiple-band antenna module, which includes a substrate and a carrier.
- the substrate has a first grounding metal surface and a first micro-strip line on a side thereof.
- the first grounding metal surface has a second micro-strip line connected thereto. There is a space between the first micro-strip line and the second micro-strip line.
- the substrate has a second grounding metal surface on the other side thereof.
- the carrier is made of ceramic material with high dielectric constant, which has a first radiative metal portion, a second radiative metal portion and a third radiative metal portion.
- the carrier is electrically connected with the substrate.
- the joint of the first radiative metal portion and the second radiative metal portion is electrically connected to the first micro-strip line.
- the third radiative metal portion is electrically connected to the second micro-strip line.
- the low-frequency segment is corresponding to a smaller area portion of the ground metal face on the PCB when the antenna carrier is fixed to the PCB. Therefore, the low-frequency segment is at a free space to enhance frequency response for the low-frequency segment and the bandwidth for the high-frequency segment.
- the blind holes and the ribs can reduce the overall weight of the carrier 1 and prevent warp of the carrier.
- the area ratio of the blind holes and the volume ratio of the blind holes can be used to adjust the effective dielectric constant of the carrier, thus adjusting resonant frequency and the bandwidth.
