A Dual-Band Antenna with AMC Reflector for WLAN Applications

摘要

We present the design of a dual-band slot antenna with high gain for wireless local area network (WLAN) covering the IEEE802.11a/b and IEEE802.116d/e standards. The antenna consists of a feed line with a complementary strip-slot pair and a parasitic slot-element and has a size of 57×40 mm^{2. The antenna is combined with a single-band artificial magnetic conductor (AMC) surface to achieve a unidirectional radiation pattern with an average gain of 9.6 dBi. The size of the antenna with the AMC reflector is 68×53 mm2. The proposed antenna was designed and simulated. The simulation results show that the antenna operates from 2.39 - 2.50 GHz and 4.90 - 5.97 GHz, which covers the 2.4, 5.2 and 5.8 GHz WLAN bands. It has a directional radiation pattern with peak gains of 7.5, 10.3 and 10.9 dBi at 2.4, 5.2 and 5.8 GHz, respectively.}
