Gap coupled and grounded miniaturized microstrip antenna

The invention relates to a gap coupled and grounded miniaturized microstrip antenna, and solves the adverse effect of the short-circuit pin parasitic inductance on grounding of a microstrip patch. Thegap coupled and grounded miniaturized microstrip antenna comprises an antenna base, a feed coaxial line, a microstrip patch, a dielectric substrate and a short-circuit pin, wherein the microstrip patch of the antenna is manufactured on the dielectric substrate; the microstrip patch radiation edge center is directly connected with an inner conductor of the feed coaxial line; the microstrip antennafurther comprises a gap, and the short-circuit pin is connected with the microstrip patch through the gap. By introducing a gap coupling grounding structure, the grounding performance of the microstrip patch through the short-circuit pin is improved, the antenna gain is improved, the structure is simple, the processing is easy, and the cost is lowered. 本公开涉及一种通过缝隙耦合接地的小型化微带天线，解决短路销钉寄生电感对微带贴片接地造成的不良影响。本缝隙耦合接地的小型化微带天线，包括天线底
