Referring to fig. 1 to 3, an embodiment of the present utility model provides a microstrip patch antenna, which includes a dielectric substrate 100, a patch assembly 200, and a ground plate 300.
The dielectric substrate 100 is a main structure supporting the patch assembly 200 and the ground plate 300, and the dielectric constant and the size of the dielectric substrate 100 have a great influence on the frequency response and the radiation direction of the microstrip patch antenna. In some embodiments of the present utility model, the dielectric substrate 100 may be an FR-4 board with a length of 50mm and a width of 28mm, where the FR-4 board is a double-sided copper-clad PCB board formed by laminating epoxy resin and glass cloth, and the dielectric constant of the conventional PCB board with respect to air is 4.2-4.7. The dielectric constant of the FR-4 board can change along with the temperature, and the maximum change range can reach 20% in the temperature range of 0-70 ℃. The change of the dielectric constant can lead to the change of 10% of line delay, the higher the temperature is, the larger the delay is, the dielectric constant can also change along with the frequency of a signal, the higher the frequency is, the smaller the dielectric constant is, and the classical value of the dielectric constant of the FR-4 board is 4.4. The dielectric substrate 100 may also be a general Printed Circuit Board (PCB) board having a uniform dielectric constant and a substantially uniform thickness.
The shape of the dielectric substrate 100 is not particularly limited, and may be circular, rectangular, or the like, and in the embodiment of the present utility model, the rectangular dielectric substrate 100 is taken as an example for illustration, the dielectric substrate 100 has a first surface and a second surface that are disposed opposite to each other, that is, the first surface and the second surface are located on opposite sides of the dielectric substrate 100.
The patch assembly 200 is disposed on the first surface of the dielectric substrate 100, where the patch assembly 200 includes a radiating element 201 and a microstrip feed element 202 that are connected to each other, and the length and width of the radiating element 201 determine the operating frequency and radiation characteristics of the microstrip patch antenna, and in the embodiment of the present utility model, the length of the radiating element 201 is 13mm, and the width of the radiating element 201 is 12mm.
The microstrip feed element 202 is used for feeding the microstrip patch antenna, the length of the microstrip feed element 202 is 11mm, the width of the microstrip feed element 202 is 4mm, and after the length and width of the radiation element 201 are determined, standard impedance of 50Ω is added to the microstrip feed element 202.
The central area of the radiation element 201 is a hollowed area, and the border of the hollowed area is defined by two first radiation edges 2011 which are oppositely arranged, and the interval between the middle positions of the first radiation edges 2011 is greater than the interval between the two end positions of the first radiation edges 2011. The ground plate 300 is disposed on the second surface of the dielectric substrate 100, and the ground plate 300 serves as a reflection surface of the microstrip patch antenna.
Equivalently, the patch assembly 200 and the ground plate 300 are disposed on both side surfaces of the dielectric substrate 100 back to back. When the microstrip patch antenna works, the radiation and receiving functions are realized by utilizing the electromagnetic field distribution of the radiation element 201 on the dielectric substrate 100. When the microstrip patch antenna receives an electromagnetic wave signal, the radiation element 201 generates an induced current, thereby converting the signal into an electrical signal and outputting the electrical signal. When the microstrip patch antenna emits a signal, the radiation element 201 generates a current, thereby generating electromagnetic waves to radiate.
It can be appreciated that, in the microstrip patch antenna provided by the embodiment of the present utility model, the central area of the radiation element 201 attached to the dielectric substrate 100 is set as a hollowed area, the boundary of the hollowed area is defined by two first radiation sides 2011 which are oppositely arranged, the distance between the two first radiation sides 2011 is gradually reduced from the middle position of the first radiation sides 2011 to the two end positions of the first radiation sides 2011, which is equivalent to that the distance between the two first radiation sides 2011 is sequentially formed with a plurality of types, and the plurality of types of distances correspond to a plurality of different frequency points, so that the bandwidth of the microstrip patch antenna is effectively expanded, the bandwidth of the microstrip patch antenna is 0.2GHz, the minimum value of return loss is-21.7 dB, and the frequency is 2.8GHz, and the microstrip patch antenna has the characteristics of miniaturization, bidirectional gain direction and high gain.
With continued reference to fig. 2 and fig. 3, unlike the foregoing embodiments, in the microstrip patch antenna provided in the embodiment of the present utility model, each first radiating edge 2011 has a first radiating segment 2011 and a second radiating segment 2011-2 connected to each other, and the second radiating segments 2011-2 are located at two ends of the first radiating segment 2011-1; the interval between the two first radiating sections 2011-1 is intermittently varied such that the first radiating sections 2011-1 are shaped like a wave or ridge, the interval between the two first radiating sections 2011-1 has a minimum peak and a maximum peak, the minimum peak and the maximum peak are alternately varied, and the interval at the maximum peak is the largest among all the intervals between the two first radiating sections 2011-1. The distance between the two second radiating segments 2011-2 is gradually reduced, i.e. the distance between the two second radiating segments 2011-2 is gradually reduced or gradually increased.
The gap in the middle area of the hollowed-out area of the microstrip patch antenna provided by the embodiment of the utility model is the largest, and the gap is smaller and smaller towards the two ends of the hollowed-out area, so that a plurality of different frequency points are formed at intervals between two opposite radiation sections of the hollowed-out area, and the plurality of different intervals correspond to the plurality of different frequency points, thereby effectively expanding the bandwidth of the microstrip patch antenna.
Fig. 4 is a spectrum contrast diagram of the microstrip patch antenna shown in fig. 1 and 2; as can be seen from the spectrogram of fig. 4, the shape formed by overlapping two virtual regular hexagons in the hollowed-out area is significantly better than the shape formed by overlapping a single virtual regular hexagon in the hollowed-out area.
Based on the above study, the influence of the shape of the hollowed-out area on each parameter of the microstrip patch antenna is determined by the shape of the superimposed virtual regular hexagons.
Fig. 8 is a schematic diagram of a shape of a hollowed-out area in a microstrip patch antenna according to an embodiment of the present utility model; FIG. 9 is a diagram showing the spectrum contrast of the microstrip patch antenna in FIG. 8; fig. 10 is a second schematic diagram of a shape of a hollow area in the microstrip patch antenna according to the embodiment of the present utility model; fig. 11 is a spectrum contrast diagram of the microstrip patch antenna shown in fig. 10.
With continued reference to fig. 1-3, and 8-11, in some embodiments of the present utility model, the spacing between two first radiant sections 2011-1 has at least three maximum peaks, and the distance between two adjacent maximum peaks ranges from 1mm to 1.5mm.
The hollowed-out area corresponding to the central area of the radiation element 201 is formed by overlapping three virtual regular hexagons with side lengths of 3mm, and removing the redundant radiation element 201 according to the overlapped outline. That is, three virtual regular hexagonal structures are arranged in a staggered manner along the vertical direction (Y direction) at an equidistant array of 1mm, and then the hollowed-out area is processed according to the outermost contour of the graph formed after superposition.
As can be seen from fig. 8 (a), three virtual regular hexagons are arranged in a staggered manner along the vertical direction (Y direction) at equal intervals of 0.5mm, and form a hollow area. As can be seen from fig. 8 b, three virtual regular hexagons are arranged in a staggered manner along the vertical direction (Y direction) at an equidistant array of 1 mm. As can be seen from fig. 8 (c), three virtual regular hexagons are arranged in a staggered manner along the vertical direction (Y direction) at an equidistant array of 1.5mm. As can be seen from fig. 8 (d), three virtual regular hexagons are arranged in a staggered manner along the vertical direction (Y direction) at an equidistant array of 2mm. As can be seen from fig. 8 (e), three virtual regular hexagons are arranged in a staggered manner along the vertical direction (Y direction) at an equidistant array of 2.5 mm. As can be seen from fig. 8 (f), three virtual regular hexagons are arranged in a staggered manner along the vertical direction (Y direction) at an equidistant array of 3mm.
Referring to fig. 9, as can be seen from the frequency and S11 simulation graphs of the 6 microstrip patch antennas, the effect of the microstrip patch antennas formed by the staggered arrangement of three virtual regular hexagons at equal intervals along the vertical direction (Y direction) and with a distance of 1mm is better, and at this time, the frequency of the microstrip patch antennas is 2.8GHz, the minimum value of the return loss of the microstrip patch antennas is-21.7 dB, and the return loss is relatively low.
As can be seen from fig. 10 (a), three virtual regular hexagons are arranged in a staggered manner in a horizontal direction (X direction) at an equidistant array of 0.5mm, and form a hollow area. As can be seen from fig. 8 b, three virtual regular hexagons are arranged in a staggered manner in a 1mm equidistant array along the horizontal direction (X direction). As can be seen from fig. 8 (c), three virtual regular hexagons are arranged in a staggered manner in an equidistant array at a distance of 1.5mm along the horizontal direction (X direction). As can be seen from fig. 8 (d), three virtual regular hexagons are arranged in a staggered manner in a 2mm equidistant array along the horizontal direction (X direction). As can be seen from fig. 8 (e), three virtual regular hexagons are arranged in a staggered manner in a equidistant array at a distance of 2.5mm along the horizontal direction (X direction). As can be seen from fig. 8 (f), three virtual regular hexagons are arranged in a staggered manner in a 3mm equidistant array along the horizontal direction (X direction).
Referring to fig. 11, it can be seen from the frequency and S11 simulation graphs of the 6 microstrip patch antennas that the effect of the microstrip patch antenna formed by the staggered arrangement of the three virtual regular hexagons along the equidistant array in the horizontal direction (X direction) is inferior to the effect of the microstrip patch antenna formed by the staggered arrangement of the three virtual regular hexagons along the equidistant array in the vertical direction (Y direction) at a distance of 1 mm. Therefore, compared with the prior art, the microstrip patch antenna formed by the staggered arrangement of three virtual regular hexagons at the equidistant array of 1mm along the vertical direction (Y direction) has better effect, the frequency of the microstrip patch antenna is 2.8GHz, the minimum value of the return loss of the microstrip patch antenna is-21.7 dB, and the return loss is relatively low.
Since the hollow area is overlapped by three virtual regular hexagons with the side length of 3mm, the first radiating section 2011-1 is the overlapped graph outline, and the second radiating section 2011-2 is one side of the original virtual regular hexagon, so the length of the second radiating section 2011-2 is 3mm.
With continued reference to fig. 1-3, and fig. 8 and 10, in some embodiments of the present utility model, two second radiating sides 2012 are disposed between two first radiating sides 2011 disposed opposite to each other, wherein one second radiating side 2012 is connected to a first end of the two first radiating sides 2011, and the other second radiating side 2012 is connected to a second end of the two first radiating sides 2011.
Equivalently, the hollowed-out area is formed by four radiation edges which are sequentially connected end to end, so that the area of the hollowed-out area can be increased, the radiation direction is further increased, and high gain is realized.
Further, the length of the second radiating edge 2012 is smaller than the length of the first radiating edge 2011, so that the hollow area is shaped like a rectangle to increase the gain of the first radiating edge 2011.
The microstrip antenna is designed according to the theoretical design mode of the traditional microstrip patch antenna, and the width W of the microstrip antenna patch is as follows:
in formula (1), f 0 Epsilon is the resonant frequency of the antenna r The relative permittivity, c, is the speed of light. Resonant frequency f of antenna 0 2.8GHz.
The length of the radiating element is:

The minimum value of the return loss of the micro-strip patch antenna miniaturized by 2.8GHz reaches-21.7 dB, and the frequency band matching performance of the micro-strip patch antenna reaches the design requirement as can be seen from figures 5 and 7. As can be seen from fig. 6, the gain direction of the 2.8GHz miniaturized microstrip patch antenna is bidirectional, and the directivity thereof meets the design requirement.
