Wideband dual-band microstrip antenna for WLAN application using organic magnetic substrate

This paper describes a novel microstrip antenna on organic magnetic substrate for WLAN systems. The dual-band operation is obtained by embedding a pair of L-shaped slots. The organic magnetic material is adopted because the substrate can reduce size of the antenna 40%, comparing with a rectangular microstrip antenna on normal dielectric substrate, and have wider bandwidths for both bands. Details of the proposed antenna design are presented and discussed, which can be candidate for the requirement of WLAN, operating in 2.45, 4.9 and 5.25GHz
