Problems solved by technology

The simulated telecommunications indicators can be very good, but the processing technology requirements are very high, and the actual measured performance indicators seen in the literature, especially the loss indicators are poor
[0004] It can be seen that none of the existing antennas have both achievable electrical performance and good manufacturability
In addition, there is no mature planar array antenna design technology that can be used for reference in the V-band and E-band

Abstract

Disclosed is a flat panel array antenna used in the frequency range of 10 GHz-100 GHz. The flat panel array antenna is characterized by comprising: a flat panel reflector, a waveguide power divider connected to a signal output end of the flat panel reflector, and an antenna radiating unit in signal connection with the waveguide power divider; the flat panel reflector is provided with a reflection side edge multiple points of which smoothly transit, the reflection side edge is located in a surface H of the flat panel array antenna and performs amplitude weighting distribution on the surface H of the flat panel array antenna; the waveguide power divider is connected to one end of the reflection side edge, is located in a surface E of the flat panel array antenna and performs uniform amplitude distribution on the surface E of the flat panel array antenna; and the antenna radiating unit comprises a rectangular waveguide and a medium grid assembled orthogonally to the rectangular waveguide. Compared with the prior art, the flat panel array antenna provided in the present invention has the features that the loss is low, a simple process is required, a low machining precision is required, and the manufacturability is good.

Description

technical field [0001] The present invention relates to an antenna system, in particular to a flat-panel array antenna used in a mobile communication microwave back-haul system and simultaneously used for wireless WIFI point-to-point (point-point link) signal transmission between base stations. Background technique [0002] An antenna is a transformer that transforms a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium, or vice versa. A component used in radio equipment to transmit or receive electromagnetic waves. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy, which use electromagnetic waves to transmit information, rely on antennas to work. [0003] At present, the commonly used antennas in the world mainly include the following schemes. 1) The microstrip line scheme is characterized by simple processin...
