A dual-band notched ultra wideband microstrip antenna
2017
A kind of dual-band notched ultra wideband microstrip antenna is presented in this paper. The reflectioncoefficient has goodnotched characteristics at rejection band of 3.3GHz∼3.7GHz and 5.15GHz∼5.85GHz by etching a complementary split ring in semicircular radiating patch. The stop bands cover WIMAX and WLAN frequency band. The designed antenna operates from 2.8GHzto12GHz. The gain is 2.3dB∼6.3dB in operating band, while the gain is less than 0dB in rejection band. And the antenna shows good omnidirectional radiation patterns in H-plane in the working band.
