Side-fed narrow-ground broadband patch antenna and design method thereof

The invention discloses a side-fed narrow-ground broadband patch antenna and a design method thereof. The bandwidth of the antenna can be adjusted by adjusting the width of the metal ground, the narrower the width of the metal ground is, the wider the bandwidth is, the ultra-wideband characteristic of the antenna can be realized within a certain range of the metal ground, and within the bandwidthrange, the wave beam width of the H-plane diagram is fully broadened; near-omnidirectional characteristics are presented at some frequency points, and meanwhile, the E-plane diagram can realize multiple wave beams by adjusting the lengths of the metal ground and the dielectric layer; in addition, compared with a conventional patch antenna of the same kind, the miniaturization design of the antennacan be achieved by reducing the size of the dielectric plate. Through corresponding adjustment, the technical problem that a patch antenna in the prior art is narrow in application field is solved. 本发明公开了一种侧馈式的窄地面宽频带贴片天线及其设计方
