Abstract
In this paper, we study a circular microstripline‐fed single‐layer single‐slot antenna. In this case, a modified circular microstrip feedline leads to good impedance matching in a wide dual band. The 10‐dB return loss impedance bandwidth is 50.8% for cellular (0.824–0.96 GHz) and GSM (0.86–0.88 GHz) operations, and is 37.1% for DCS (1.71–1.88 GHz), PCS (1.85–1.99 GHz), and IMT‐2000 (1.90–2.20 GHz) operations. We obtain the result for the return loss of exhibited multi‐band characteristics. The peak antenna gain is 4.61 dBi and 3.80 dBi for the lower (cellular and GSM) and upper (DCS, PCS, and IMT‐2000) bands, respectively. © 2003 Wiley Periodicals, Inc.
