Heart shaped monopole antenna with defected ground plane for UWB applications

摘要

In this paper a monopole antenna with shape of heart for Ultra Wide Band (UWB) applications is proposed. The structure is a simple patch with shape of heart designed on FR-4 substrate and fed by a 50 Ohms microstrip line. The ground plane of the antenna has been modified including several defects to improve its behavior in matching and wideband. A parametric study has been performed to the semicircular slots located in the ground plane area. The frequency range measured for S11<;-10dB was from 2.7-26 GHz. The total dimensions of the antenna are 48×40mm (W × L).
