Abstract

The invention provides a dual-port multi-mode common-caliber space scanning antenna and array based on an SSPP structure in the technical field of communication. The dual-port multi-mode common-caliber space scanning antenna comprises an SMA connector, a dielectric plate, a symmetrical SSPP metal transmission line, a floor, a gradual change microstrip line and a fan-shaped microstrip. The symmetrical SSPP metal transmission lines and the floor are arranged on the front surface of the dielectric plate, and the gradient microstrip line and the fan-shaped microstrip are arranged on the back surface of the dielectric plate; the floor is provided with a circular gap and a slot line, and the circular gap and the slot line are connected. The gradient microstrip line is connected with the fan-shaped microstrip line. By changing the phase difference between the two feed ports, the antenna is excited to work in multiple modes, so that hemispherical scanning of a directional diagram in a three-dimensional space is realized.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular, to a dual-port multi-mode common-aperture spatial scanning antenna and array based on an SSPP structure, and to a dual-port antenna and array based on an artificial surface plasmon polariton (SSPPs) structure. Port multimode common aperture space scanning antenna. Background technique [0002] With the development of antenna technology, antenna electronic scanning technology is playing an increasingly important role. At present, phase scanning and frequency scanning are widely used. The working principle of the frequency scanning antenna is to make the phase relationship between the antenna elements or the lobe pointing change with the working frequency. loss increases. The phase-scanning antenna uses a phase shifter to control the phase of the antenna unit to realize beam scanning. The antenna system is relatively complicated, and the working mode of the antenna ...
