Abstract

A conventional CPW‐fed loop‐slot antenna, incorporating a PBG structure in the feeding network, is presented. Experimental results show that the PBG structure with cross‐shaped lattices exhibits a well behaved band‐stop characteristic; furthermore, the impedance bandwidth of the proposed antennas also becomes wider than that of the conventional CPW‐fed slot antenna. In this design, the impedance bandwidth can reach 1320 MHz, which is about 60% with respect to the central frequency of 2200 MHz. © 2004 Wiley Periodicals, Inc.
