Various Slotted UWB Antenna for IEEE 802.15.3a Application
The basic circular monopole antenna exhibits a 10dB return loss bandwidth over the entire frequency band, the paper proposed a modified version of simple circular monopole antenna for WPAN application. The antenna offers excellent performance in the range of 2-12GHz. The antenna is designed on FR4 substrate and fed with 50ohms micro strip feed line. The antenna is suitable for operating frequency of 7GHz. It is shown that return loss of the antennas at 7GHz is better than -10dB and VSWR obtained is less than 2.
