Description
Technical Field
The invention relates to the field of antenna design, in particular to a wide-angle scanning dual-polarized broadband element antenna and an antenna array.
Background
Antennas are important components in radar, communication, and detection systems, and overall system performance is greatly affected by the performance of the antenna components. In the last two decades, the rapid advance of semiconductor devices, integrated circuits, computers and other technologies has promoted the development of phased array technology, and the requirements of radar and other systems on the frequency bandwidth and the scanning angle are higher and higher, which puts more rigorous requirements on the broadband performance and the wide-angle scanning performance of antennas.
The dual-polarized antenna is provided with independent polarization channels, and can realize the transmission and the reception of two mutually perpendicular polarized electromagnetic wave signals. The dual-polarized antenna has the advantages of frequency multiplexing, receiving and transmitting integration, polarization diversity, polarization agility and the like, is applied to communication equipment, is beneficial to increasing communication data volume, and is applied to radar equipment, and is beneficial to target full-polarization echo signal receiving and interference signal suppression. Conventional dual polarization antenna forms include iso-waveguide slot antennas, microstrip antennas, and the like. At present, the dual-polarized antenna has certain application in radar with a reflecting surface system, but has less application in the field of phased array radar. With the rapid development of polarization technology research in recent years, the demand of the polarization phased array for antenna units and arrays is increasing, and the demand is higher.
Therefore, how to realize the wider bandwidth and the better wide-angle scanning performance of the dual-polarized array antenna while considering both the polarization isolation degree and the array plane integration becomes a problem to be solved urgently.
In a patent "broadband wide-angle scanning dual circularly polarized microstrip antenna" (publication number: CN103972658A) of the middle antenna 38, a crossed microstrip element antenna is proposed, which is composed of two crossed microstrip elements, an independent antenna cover integrated with a parasitic radiation unit, an integrated skirt and a base provided with a support lug, and forms a modular unit structure with two radio frequency ports. The structure has the advantages of flexible form, easy processing and wide-angle scanning; in a patent 'composite microstrip printed dipole broadband antenna' (publication number: CN1815811) of southeast university, the problems of how to improve the space bandwidth of a microstrip antenna and how to effectively control the space bandwidth of the microstrip antenna are mainly solved, and the problem of mutual coupling among antenna array units is considered; the 'dual-polarized antenna' (publication number: CN105356041A) proposed by XianHua adopts two dipole units and a metal reflector to realize dual polarization, but is not suitable for being used as a unit of a large-scale array; the Liwei 'a design of a novel broadband microstrip dipole antenna' of Nanjing post and telecommunications university, proposes that the bandwidth is expanded by etching a circular groove on the radiation surface of the antenna; the sons of the university in south-east realizes dual-polarization radiation based on a coupling feed microstrip patch, and obtains higher polarization isolation.
The dual circular polarization antenna with wide-band and wide-angle scanning, which is proposed by the medium antenna 38, comprehensively considers the problems of electrical performance and mechanism strength, but no specific implementation is given to the form of dual circular polarization, the bandwidth of the frequency band (VSWR is less than or equal to 1.9) reaches 21.2%, and when the dual circular polarization antenna is used as a phased array, each antenna unit is designed and installed as an independent individual, so that the consistency of unit directional patterns (processing, installation, welding and antenna housing) is greatly influenced; the southeast university realizes that the space bandwidth of the antenna is controlled by adjusting the height of the composite unit and the distance between the composite unit and the oscillator arm in the proposed structure, but the bandwidth of the frequency band still has great limitation, the bandwidth (about-10 dB) is only about 10 percent, the width difference of two-dimensional main lobes of a directional diagram of the microstrip antenna unit is great, and the problem of wide-angle scanning of the dimension with the narrow main lobe is not considered; the realization scheme of the surface etching circular groove proposed by Liwei of Nanjing post and telecommunications university has narrow antenna beam width, which is not beneficial to wide-angle scanning of an array antenna; the coupled feeding dual-polarized antenna described by sons of university in southeast university has high isolation in a coupled feeding mode, but the feeding mode is too complex for a phased array of a certain scale and has high cost.
