Design of Compact-Circular Monopole UWB Antenna with Dual Notch Bands

A current UWB antenna with compact-circular monopole UWB antenna support by a microstrip line with a semi-rectangular ground plane is given in this paper to realize an operating bandwidth from 3.3GHz to 12GHz. Low-cost FR4-lossy material with a dimension of 12mm×18mm×1.6mm has taken place used to design the antenna. The proposed antenna is incorporated with L-shape complimentary slots with discontinuities. The I-shape slots are placed in such that the discontinuities face in the feed line and it will generate a static resonance which is the reason for the dual notch bands covering the frequency ranges of WiMAX and WLAN.
