Abstract

A new design of a dual‐band planar inverted‐L patch antenna suitable for applications in WLAN (2400–2484 MHz) and HIPERLAN (5150–5350 MHz) systems is proposed. By using an inverted‐L radiating patch, in which two additional narrow slits are inserted at the radiating edge to effectively control the excited patch surface current distributions, the proposed antenna can generate two operating frequencies at 2.4 and 5.2 GHz. In addition, wide impedance bandwidths are obtained. The proposed antenna has 10 dB return‐loss bandwidths of 7.5 and 8.1% in the 2.4 and 5.2 GHz bands, respectively, and the obtained peak antenna gain also reaches 5.7 and 6.4 dBi for operating frequencies within the 2.4 and 5.2 GHz bands, respectively. © 2001 John Wiley & Sons, Inc.
