T-shaped/inclined-L-shaped current guide slit dual-frequency broadband dual-circular polarization microstrip laminated antenna

Abstract

The invention relates to a T-shaped/inclined-L-shaped current guide slit dual-frequency broadband dual-circular polarization microstrip laminated antenna and belongs to the broadband microstrip antenna field. The microstrip laminated antenna is provided with an upper layer dielectric substrate, a lower layer dielectric substrate and a grounding plate; an upper layer patch is laid on the upper surface of the upper layer dielectric substrate; the upper layer patch is a hexagon-shaped radiation patch, circular grooves being cut at upper and lower opposite angles, rectangular grooves being cut at left and right opposite edges; oblique L-shaped slits are formed between the circular grooves and the rectangular grooves; T-shaped slits or slits of which the shape is similar to T are formed between the oblique L-shaped slits; two ends of the horizontal part of each slit of which the shape is similar to T are provided with folded line structures; through the loading of the T-shaped slits, the slits of which the shape is similar to T and the oblique L-shaped slits, the flowing direction of current at the surface of the antenna can be guided, and therefore, the gain performance of the antenna can be optimized; a lower layer patch is laid on the upper surface of the lower layer dielectric substrate; the lower layer patch is a hexagon-shaped radiation patch, circular grooves being cut at right and left opposite angles, rectangular grooves being cut at upper and lower opposite edges; the upper layer patch is arranged in a leftward eccentrically manner relative to the lower layer patch, so that the resistance matching of the single-feed laminated multi-frequency antenna can be realized; and a coaxial feed opening is formed at the upper layer patch.
