Abstract

The invention discloses a phased array dual-polarization broadband wide-angle scanning array antenna applied to neural network driving. The array antenna comprises a first dielectric plate, a second dielectric plate and a third dielectric plate which are stacked up, middle and down; a first rectangular patch is printed on the upper surface of the first dielectric plate; a second rectangular patch and a third rectangular patch are printed on the upper surface of the second dielectric plate; a metal floor is printed on the lower surface of the second dielectric plate; a linear microstrip line and an L-shaped microstrip line are printed on the lower surface of the third dielectric plate; the rectangular metalized gap penetrates through the first and second dielectric plates and is connected with the metal floor; and the linear microstrip line is connected with the first rectangular patch through metalized via holes penetrating through the third dielectric plate, the second dielectric plate and the first dielectric plate. Wherein the first rectangular patch takes the second rectangular patch as a reflecting plate for radiation, and has the characteristics of low profile and broadband; the beam width of the two polarization lower antenna units is widened through the rectangular metallization gap, and the dual-polarization, broadband and wide-angle scanning performance is achieved while it is guaranteed that the antenna array has the structural advantages.

Description

technical field [0001] The invention belongs to the technical field of antennas, and relates to a dual-polarization wide-bandwidth angular scanning array antenna, in particular to a dual-polarization wide-bandwidth angular scanning array antenna applied to a neural network-driven phased array. Background technique [0002] Future radar detection technology should be able to realize real-time, continuous, and seamless detection and identification of various conventional, stealth, weak, maneuvering, ultra-high-speed, and stationary targets under complex and harsh electromagnetic, geographical, and meteorological conditions. This requires the radar to have the ability to quickly form arbitrary beams, and the phased array radar based on neural network can model and fit the expected waveform and the mapping space of array element parameters, and the training and inference model of the beamforming neural network Relatively simple, so it has the ability to quickly form a variety of...
