Abstract
A dualband antenna that consists of two radiating slots is investigated in this paper. The slots are cut onto an L-probe-fed hollow rectangular conducting cavity, which is covered by a protective dielectric layer. The two slots give two resonant modes that lead to a dualband operation. It is very favorable that the frequencies of the two resonant modes can be adjusted independently, which greatly facilitates the dualband 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, and radiation efficiency of the antenna are studied. Reasonable agreement between simulation and experiment is obtained. © 2007 IEEE.
