Abstract

A compact circular monopole shaped antenna is designed to operate at the dual band, and it is modified as half circle strip loaded circular monopole antenna with defected ground structure (DGS). The proposed antenna consisting of the combination of circular radiating element and half circle strip on the top side of the FR4 substrate material with permittivity 4.4. The bottom side a dumbbell-shaped DGS is incorporated to enhance the antenna bandwidth parameter. The proposed antenna is providing a bandwidth of 8 GHz and covering the UWB range. A peak realized a gain of more than 3 dB and directivity of 3.6 dB is achieved from the current design. The proposed antenna is providing excellent impedance and radiation characteristics in the operating band.
