摘要: In this paper, a dual-band microstrip slot antenna over suspended substrate with an antipodal parasitic element is proposed for wireless local area network systems operating at 2.4, 5.2, and 5.8 GHz. The composed of multi layers flame retardant-4 (FR4) air/foam substrates. foam/air included coaxial single-feed pin the FR4 comprised modified T-shaped patch U-shaped around it. configuration improves compactness, impedance bandwidth, radiation pattern. realized proportionately small in size (17 × 20 mm2) experimental result shows that covers 2.39---2.5 5.1---6.05 GHz 10-dB return loss bandwidth. Furthermore, has good patterns both x---z y---z planes desired frequency ranges.
