摘 要：Abstract：The invention relates to a slot-loaded ultra-broadband monopole antenna simultaneously with a stable directional diagram and high out-of-band rejection capability. The slot-loaded ultra-broadband monopole antenna comprises a dielectric substrate, radiation patches, an inter-digital coupling line, a multimode resonator, a micro-strip feeder, a grounding plate and a coaxial cable, wherein the radiation patches, the inter-digital coupling line, the multimode resonator and the micro-strip feeder are closely attached to the upper surface of the dielectric substrate; the radiation patches are connected with the multimode resonator through the inter-digital coupling line; the other end of the multimode resonator is connected with the micro-strip feeder through the same inter-digital structure; the grounding plate is closely attached to the part, close to the lower end, of the lower surface of the dielectric substrate; an inner conductor of the coaxial cable is connected with the micro-strip feeder on the upper surface of the dielectric substrate, and an outer conductor of the coaxial cable is connected with the grounding plate on the lower surface of the dielectric substrate. According to the slot-loaded ultra-broadband monopole antenna, a ultra-broadband monopole antenna design with the stable directional diagram and a good out-of-band rejection function is effectively implemented, and in addition, the antenna has the advantages of miniaturization, compact structure, easiness in manufacturing and debugging, and the like.
