Cyclic Gradient Patch Bionic Array Ultra-Wideband Antenna

Abstract

The invention relates to an ultrabroad frequency band antenna with a cyclic gradual-change patch bionic array. The antenna comprises a substrate, an antenna grounding plate attached to the backside ofthe substrate, and a cyclic gradual-change patch bionic array radiation patch attached to the front surface of the substrate, the antenna grounding plate is a totally-conductive grounding structure,and the cyclic gradual-change patch bionic array radiation patch is an antenna array formed by arrangement of 48 cyclic gradual-change patch antennas according to a butterfly-shaped bionic array structure. According to the ultrabroad frequency band antenna with the cyclic gradual-change patch bionic array, the dimension is small, the radiation intensity is high, the work performance is stable, excellent ultrabroad frequency band operating capability and large performance redundancy are achieved, and the utrabroad frequency band antenna with the cyclic gradual-change patch bionic array, which covers the second to fifth mobile communication frequency bands, the radio frequency recognition frequency bands, ultrabroad communication frequency bands and mobile digital television frequency bands,is achieved.
