Abstract

In this paper, a circular slot antenna fed by an offset microstrip-fed line is proposed. The antenna exhibit dual-band characteristics. The two operating frequency bands are: 1.83--2.73 GHz and 5.36--7.63 GHz, which are of impedance bandwidth 39.5% and 34.9% respectively. The bands are suitable for PCS, UMTS, IMT-2000, ISM, Bluetooth, RFID and WLAN applications. A parametric study has been carried out by varying the location of the feedline to investigate its effect on the resonant frequency. Impedance, radiation and gain characteristics of the proposed antenna are also presented and discussed.
