Problems solved by technology

As a result, the number of servo motors required by the mobile satellite communication system has doubled at the same time, which not only increases the volume, which is not conducive to the overall compactness of the system, but also leads to a substantial increase in cost and power consumption. The other two VICTS phase control The array antenna is designed independently, and it is difficult to control the beam direction of the receiving frequency band and the transmitting frequency band to be consistent

Abstract

The invention discloses a receiving and transmitting integrated VICTS phased array antenna. The antenna comprises a radiation layer, a slab waveguide layer and a feed layer which are sequentially arranged from top to bottom, wherein the feed layer is used for transmitting a TE10 mode input into the feed layer, converting the TE10 mode into a quasi-TEM mode and coupling the quasi-TEM mode to the slab waveguide layer, the slab waveguide layer is used for transmitting the quasi-TEM mode and coupling the quasi-TEM mode to the radiation layer, and the radiation layer is used for radiating the quasi-TEM mode to a free space. The antenna has the advantages that transmitting and receiving functions can be realized at the same time, the size, cost and power consumption of a mobile satellite communication system can be reduced when the antenna is used in the mobile satellite communication system, and consistent beam pointing of a transmitting frequency band and a receiving frequency band can be realized.

Description

technical field [0001] The invention relates to a VICTS antenna, in particular to a VICTS phased array antenna with consistent beam direction. Background technique [0002] The CTS (Continuous Transverse Stub) array antenna was first proposed by Raytheon Corporation of the United States in the 1990s, and a large number of planar antennas have been developed. As a further evolution of the CTS antenna array, VICTS (Variable inclination continuous transverse stub) technology can realize a two-dimensional beam scanning array with low profile, low power consumption and strong mechanical robustness while inheriting the original high efficiency. [0003] Because the VICTS phased array antenna has a large interval between the receiving frequency and the transmitting frequency, the common radiation surface of the two frequency bands is prone to dispersion, making it difficult to keep the direction of the receiving beam and the transmitting beam consistent, and the design of the commo...
