Abstract

In order to avoid the mutual interference between UWB system and narrowband communication system, the ultra wide band antenna with notch characteristic on diamond shaped patch antenna is improved. The coplanar wave guide (CPW) feed structure and a larger groove rectangle etching on the ground and rhombus radiating elements structure are designed to achieve ultra-wide band characteristics. An Lshaped minor radiation patch is added in the antenna ground plate to realize WiMAX and WLAN dual-band notch. An Eshaped groove on the rhombus radiating elements is etched to achieve the ITU 8G single notch. The simulation and experimental results show, the VSWR is less than 2 in 3-12GHz operating frequency band, and this structure antenna has a good notch characteristic in the frequency of 3.2-3.7GHz, 5.1-5.8GHz and 8.2-8.7GHz. In addition to the operating band of ultra-wide band range apart from three resistance bands, the antenna has good radiation characteristics and stability gain.
