Abstract

The invention discloses a non-array aperture antenna wave beam tilt electronic antenna and an implementation method thereof. The non-array aperture antenna wave beam tilt electronic antenna comprises an aperture antenna and a control antenna. Electric field distribution in a feed source loudspeaker aperture face is changed through an assembly structure and an excitation element antenna used for producing a tilt wave beam, aperture face antenna main wave beam tilt is achieved, and scanning of a wave beam in space is formed through a periodic excitation patch antenna. The aperture antenna is a feedforward reflector antenna. The control antenna comprises an interference antenna, a fixing ring, a fixing base and a compression plate. The polarization mode of the control antennal includes but not limited to linear polarization, dual linear polarization, circular polarization and dual circular polarization. The defects in the prior are overcome, antenna units do not need to be arrayed according to the method, and the non-array aperture antenna wave beam tilt electronic antenna has the advantages of being simple in structure, easy to implement and convenient to control.

Description

technical field [0001] The invention relates to the technical field of beam control, in particular to a non-array aperture antenna beam tilting electronic antenna and a realization method. Background technique [0002] The existing methods for realizing beam scanning mainly include: [0003] 1) Mechanical scanning uses a motor to drive the antenna to periodically move around the connection with the satellite to realize the spatial scanning of the main beam of the antenna. This method is limited by the mechanical structure, the scanning speed is low, and the accuracy is poor. [0004] 2) Monopulse scanning uses the sum-and-difference antenna waveguide network to obtain antenna attitude information and drive the antenna. This method is very accurate, but it is expensive and requires a high-precision tracking receiver. [0005] 3) Phased array scanning uses a large number of transceiver components to form an array, and realizes scanning beams by controlling the phase amplitu...
