摘要：

Two types of cavity-backed slot (CBS) antennas fed by a microstrip line and operating at 5.8 GHz are described in this letter. One is a broadband linearly polarized CBS antenna, which can provide 34% bandwidth for a 10-dB return loss. The other is a circularly polarized dual T-shape CBS, which has 4% bandwidth for a 3-dB axial ratio and a 15% bandwidth for a 10-dB return loss. The simulated and measured results of both antennas are in good agreement. (C) 2002 Wiley Periodicals, Inc.
