Abstract :
In this paper, a dualband antenna that consists of two radiating slots is studied. The slots are cut onto an L-probe-fed hollow rectangular conducting cavity, which is covered by a protective dielectric layer. Dualband operation can be obtained by exciting the two resonant modes of the two slots. It is found that the frequencies of the two resonant modes can be adjusted independently, which greatly facilitates the antenna design. To demonstrate the idea, a dualband antenna for 2.4/5.2-GHz IEEE802.11a/b WLAN applications is designed. The return loss,radiation pattern, gain the antenna are studied. Reasonable agreement between simulation and experiment is obtained.
