Abstract
In this paper, A planar UWB antenna with notched WLAN band, 802.11a band (5.15 ~ 5.825GHz), by using slot and slit is designed by using CST Microwave Studio. The notched bandwidth can be controlled by the length and width of the slot and slit in the patch and ground plane and it's radiation characteristics are examined through the experiments. The bandwidth based on the -10dB return loss level can be covered the full UWB band (3.1 ~ 10.6GHz) with a notched WLAN band (5.147 ~ 5.83GHz). Also, the experimental radiation pattern is almost omnidirectional in the H-plane.
