Problems solved by technology

However, the microstrip antenna is a kind of resonant antenna, its relatively narrow bandwidth and small power capacity limit its application range.
[0003] At present, the microstrip antennas working in the C-band have narrow bandwidth, can only cover a part of the C-band, can only achieve single-polarization receiving and transmitting antennas, and the technical problems of cross-polarization are too high.

Abstract

The invention mainly belongs to the technical field of communication antennas, especially the technical field of satellite antennas, and specifically relates to a C-band receiving and transmitting integrated microstrip array antenna. The antenna comprises a plurality of receiving and transmitting shared antenna units which respectively consist of a receiving and transmitting shared drive paster and a receiving and transmitting shared parasitic paster, wherein the receiving and transmitting shared antenna units are used for achieving the integration of a C-band receiving and transmitting antenna. The microstrip array antenna also comprises a feed network, a receiving feed port, and a transmitting feed port. The receiving feed port and the transmitting feed port are respectively connected with the feed network. The feed network achieves the feeding of the receiving and transmitting shared drive pasters. The antenna is large in bandwidth, is simple in structure, is high in gain, is in port isolation degree, is excellent in cross polarization performances, can be conveniently extended to be a larger array, and has the incomparable advantages for the C-band satellite communication application.

Description

technical field [0001] The invention mainly belongs to the technical field of communication antennas, in particular to the technical field of satellite antennas, and specifically relates to a C-band transceiver integrated microstrip array antenna. Background technique [0002] Most of the traditional satellite communication antennas use parabolic antennas, but they are large in size and heavy in weight, making it extremely inconvenient to carry and move, especially to adapt to modern portable communication devices, which highlights its shortcomings. Therefore, it is small in size, light in weight, low in profile, easy to manufacture, good in price, easy to conform, and can obtain a wide-lobe pattern in one direction. The maximum radiation direction is in the normal direction of the plane, and it is easy to realize linear polarization and circular polarization. Microstrip antennas with such characteristics have been extensively researched and applied. However, the microstrip...
