Abstract :
This paper presents the design and testing of a wide-band monopolar wire-patch antenna. The proposed antenna consists of a circular patch that is shorted to the ground plane by four copper wires and is fed by an L-probe at its center. For the patch height and patch radius of 0.092 and 0.179 free space wavelengths at 0.893 GHz, this antenna possesses a 14-dB return loss bandwidth of 27.1%, which is 9 times wider than that of similar type of antenna reported in the literature. Also, it has an average gain of 2.6 dBi and monopole-like radiation patterns over this bandwidth. As this antenna has wide impedance bandwidth and relatively small size, it is very suitable for the indoor mobile communication systems.
