Problems solved by technology

There is another antenna, although the gain in the coverage area is high, but the system is complicated, the size is large, and the weight is heavy.
Therefore, for the performance requirements of miniaturization, sharing of transceivers, wide coverage and high gain, the above antenna design forms have their own limitations and cannot be fully realized.
In summary, the existing traditional technology can no longer meet the antenna application requirements of miniaturization, wide coverage beam (elevation ±70°, azimuth omnidirectional) and high gain (greater than 5dBi)

Embodiment

[0081] Such as figure 1 and figure 2 As shown in (a), (b) and (c), the miniaturized transmitting and receiving shared wide-beam coverage antenna consists of antenna radiator 1, octagonal truss and octagonal prism structure 2, built-in transceiver component 3, base plate 4, radio frequency connector 5, The low-frequency connector 6 and the upper cover plate 7 of the octagonal platform are composed. In order to achieve miniaturization, the transceiver microstrip antenna unit adopts a high dielectric constant dielectric substrate, using Rogers TMM10i plate, the dielectric constant is 9.8, the thickness is 0.035λ, single-point feeding; the circular polarization performance is realized by four-sided grooves At the same time, the notch further realizes the miniaturization of the antenna unit. The antenna unit is optimized and simulated by the commercial software HFSS v15, and the design of the transceiver antenna unit is completed (the unit gain is about 6-7dBi, the beam width of...

Abstract

Disclosed is a small-sized transceiving shared broad-wave-beam coverage antenna. The coverage antenna comprises an antenna radiator, an octagonal-prism table and octagonal-prism column structure, a built-in transceiving assembly, a bottom plate, radio-frequency connectors, a low-frequency connector and an octagonal-prism table upper cover plate, wherein the antenna radiation body comprises eight receiving antenna units and eight transmitting antenna units, and a group of receiving and transmitting units are arranged on the side surface of each prism table; the octagonal-prism table and octagonal-prism column structure adopts an integrated structure with the octagonal-prism table on the upper part and the octagonal-prism column on the lower part; the built-in transceiving assembly comprises a receiving assembly and a transmitting assembly; the bottom plate is used for fixing the built-in transceiving assembly; and the radio-frequency connectors comprise a transmitting radio-frequency connector and a receiving radio-frequency connector. The characteristics of small size, transceiving sharing, and high-gain coverage performance of 5dBi in a broad-wave-beam coverage region at a pitching angle of minus or plus 70 degrees is realized by virtue of the crossed array design of the receiving and transmitting antenna units on the adjacent side surfaces of the octagonal-prism table, 16 oval-like wave beam wide coverage wave beam design and small-sized comprehensive design.

Description

technical field [0001] The invention relates to a miniaturized transmitting and receiving shared wide-beam coverage antenna, which belongs to the technical field of antennas. Background technique [0002] With the development of military and civilian communication technology, the complexity and system performance of communication systems are constantly improving, and users are constantly pursuing the maximization of system load performance. One of the problems brought about by this is how to solve the problem under the limited application platform capabilities. , greatly improving the utilization efficiency of the platform, using fewer or smaller devices to achieve higher and better system performance. That is to say, the application platform puts forward more stringent requirements for the miniaturization of the load equipment, especially the antenna. [0003] On the other hand, wide coverage and high gain performance have always been hot topics in the field of antenna res...
