Description
Technical Field
The invention belongs to the technical field of broadband array antennas, and particularly relates to a broadband dual-polarized tightly coupled antenna unit and an array.
Background
With the development of wireless communication technology, the requirements of information data transmission rate are higher and higher, and according to shannon theorem of wireless data transmission, the channel capacity of a communication system is proportional to the system bandwidth, which means that the bandwidth requirements of the communication system are wider and wider. Meanwhile, considering that the dual-polarized antenna can radiate or receive a plurality of pairs of electromagnetic waves in a specific polarization direction, full duplex operation and frequency multiplexing functions can be realized, and the orthogonal polarization mode is beneficial to obtaining higher cross polarization level, so that the multipath attenuation problem is relieved, and the communication quality is enhanced. At present, the broadband dual-polarized antenna is widely applied to various fields of civil affairs, military affairs and the like.
The conventional broadband antenna mainly comprises: (1) a frequency independent antenna; (2) Vivaldi antennas; (3) wideband printed slot antennas, etc. The antennas have the problems of large volume, high manufacturing cost, complex manufacturing and the like. In 2003, munk teaches a novel broadband antenna structure, a tightly coupled antenna array (Tightly Coupled Dipole Array, TCDA), and the core idea is to fully utilize coupling between array elements to widen the bandwidth.
In designing a tightly coupled antenna, a broadband balun structure is often required to be introduced between a feed port and a dipole in order to balance feed, which results in complex feed structure, high antenna section and complex processing. In the existing searchable literature, the problem of port mismatch caused by the cutoff effect of the edge vibrators after the tightly coupled vibrator array is not fully studied and discussed.
For example, in 2020, cui Xuewu et al, in a patent (application number: CN 202010520723.4) entitled "a low-profile wide-bandwidth angle tight-coupling antenna unit and array", a feed structure with microstrip line aperture coupling is adopted, so that an active standing-wave ratio <2 is satisfied in the 4-8GHz band. The structure avoids adopting a complex broadband balun structure, has a simple structure and realizes a low profile. But the bandwidth of the antenna structure is not very wide, and a plurality of frequency bands are difficult to cover.
For example, in 2019, cang Yongdong et al published a patent (application number: CN201910861174. X) entitled "a VHF band tightly coupled planar dipole array antenna," which is to realize that the antenna satisfies an active standing wave of less than 3 in the frequency band of 100-350MHz, and the antenna profile height is 0.1 low frequency wavelength. Particularly, in order to improve the edge cutting effect, the oscillator arm of the edge unit positioned at one side of the edge is prolonged, and the resistor is connected in series with the extension part of the oscillator arm, so that the active standing wave ratio of the edge oscillator in the frequency band of 100-350MHz after the array is realized is less than 2.3. The antenna has a simple structure and a lower profile, but an active device is adopted when the problem of edge truncation is solved, so that the bandwidth is greatly limited, and the method is only suitable for the condition that the dipole phase centers are consistent.

The first circuit layer (21) comprises a dual-polarized oscillator unit, specifically, the dual-polarized oscillator unit comprises two pairs of oscillator arms (211) which are mutually perpendicular, each oscillator arm extends a section of branch along 45 degrees at two sides of the tail end to optimize low-frequency matching, the two sections of branch extend in different lengths, and the lengths are respectively adjusted to balance port isolation performance and polarization isolation of the antenna; the directions are orthogonal to achieve dual polarization performance.
The second circuit layer (22) includes a metal coupling wafer (221) and a first metal patch structure (222) for feed optimization. A metal coupling wafer (221) is located below the ends of the transducers to increase coupling between adjacent transducers.
The third circuit layer (23) and the fourth circuit layer (24) have the same structure and comprise a second metal patch structure (231) optimized by feeding, and the structure helps to uniformly feed and stabilize the electromagnetic environment;
the unbalanced feed structure (3) comprises a coaxial connector (311) and two pairs of ground metal vias (312). The coaxial connector is positioned on the left vibrator arm of the horizontal dipole/the upper vibrator arm of the vertical dipole and penetrates through the third medium layer to the sixth medium layer and the metal floor. The two pairs of grounding metal through holes (312) are positioned on the right oscillator arm of the horizontal dipole/the lower oscillator arm of the vertical dipole and penetrate through the third microwave medium layer to the sixth microwave medium layer.
Further, the first dielectric layer (11) has a height of 0.813mm and a dielectric constant of 3.55;
further, the second dielectric layer (12) has a height of 4mm and a dielectric constant of 2.2;
further, the third dielectric layer (13) has a height of 0.254mm and a dielectric constant of 2.2;
further, the fourth dielectric layer (14) has a height of 2mm and a dielectric constant of 2.55;
further, the fifth dielectric layer (15) has a height of 0.813mm and a dielectric constant of 3.55;
further, the sixth dielectric layer (16) has a height of 2mm and a dielectric constant of 2.2;
as shown in fig. 3, the total length l3=10.5 mm of the vibrator arm (211), the length l1=4.1 mm of the extending branch at the tail end of the vibrator arm, l2=4.53 mm. According to the PCB process, the etching precision is 0.1mm, and the small angle is cut off at the tail end of the vibrator so as to meet the processing requirement.
As shown in fig. 4, the cross-sectional views of the fourth dielectric layer (14), the fifth dielectric layer (15) and the sixth dielectric layer (16) after unit and group are shown, and all three dielectric layers are partially dug. L6=3.9mm, l7=10.7mm in the unit structure; and after the array is assembled, the whole body is hollow.
As shown in fig. 5, the coaxial connector (311) is located on the left dipole arm of the horizontal dipole/the upper dipole arm of the vertical dipole, penetrates through the third to sixth dielectric layers and the metal floor, and the dipole arms are connected with the inner conductors of the coaxial connector.

Both metallized through holes are connected with the vibrator arm and are positioned on the same horizontal line/vertical line. The feed of the dipole antenna element requires differential feed (also known as balanced feed) while the coaxial transmission line is unbalanced, which may cause common mode resonance in the operating frequency band, affecting the antenna performance. The common mode resonance can then be shifted outside the operating band by introducing a grounded metal via. Compared with the common gradual change balun, the structure is simple, easy to process, stable and reliable.
As shown in fig. 7, the feeding optimized metal patch structure (222, 231) in fig. 6 is introduced, the infinite period model of the broadband dual-polarized tightly coupled antenna has standing wave ratio of less than 1.4 at normal angle, standing wave ratio of less than 2 at E-plane and standing wave ratio of less than 2.5 at 45-degree scanning angle, and the full-band and large-angle matching is good. Compared with standing wave ratio of the antenna infinite period model under normal angle and 45-degree scanning angle after the feeding optimization metal patch (222, 231) is removed in fig. 8, the feeding optimization metal patch (222, 231) has obvious medium-high frequency optimization effect. The feeding structure and the optimized feeding metal patch structure are simple in structure, and meanwhile resonance points brought by common mode resonance in an operating frequency band are removed by utilizing the grounding metal through holes, so that uniform feeding is assisted by the metal patch structure, and good matching characteristic of the full operating frequency band is achieved.
Example 2
A broadband dual polarized tightly coupled antenna array is comprised of 4 x 4 antenna elements as shown in fig. 9. With reference to fig. 10 to 11, redundant vibrators without feed structures are added around the array to form a complete grid structure. Meanwhile, a metal through hole (41) is added at the tail end of the edge working oscillator, the oscillator arm (211) and the metal coupling wafer (221) are connected, and a metal short-circuit column (42) is added at the tail end of the redundancy oscillator at the central position of the edge to connect the redundancy oscillator and the metal floor (17), so that the problem of mismatch of ports of the edge working oscillator caused by edge cutting-off effect is relieved.
As shown in fig. 12, after the above measures are taken, the 4×4 broadband dual polarized tight coupling antenna array is excited to 16 pairs of elements in all vertical directions. By observing the active standing wave ratios of all 16 ports, the active standing wave ratios of the rest vibrators in the working bandwidth are less than 2 except that the standing wave ratios of the 14 ports and the 15 ports float up to 2.5 in the low-frequency part, so that the full-frequency-band matching of all the ports is basically realized well. As shown in FIG. 13, the antenna array has good radiation performance, the polarization isolation is greater than 15dB at 4GHz, and the polarization isolation is over 20dB at 8GHz and 12GHz, so that the index requirement is met.
In summary, the invention optimizes the vibrator shape and the feed structure, satisfies that the standing wave ratio is smaller than 1.4 at normal incidence in the frequency band of 4-12GHz, satisfies that the standing wave ratio is smaller than 2/2.5 when the E face/H face scans to +/-45 degrees, and has good full-band matching because all the standing wave ratios of ports at normal incidence after the array is arranged are smaller than 2.5.
