Design and development of an I-slot antenna for dual-band applications

Abstract

In the present work, a dual band Microstrip patch antenna is designed, fabricated and tested. The proposed antenna consists of an I-slot in a rectangular patch over a partial ground which operates at higher order TM02 mode. The presented design is suitable for 3G and WLAN applications as it produces dual beams at 1.9GHz and 5.7GHz respectively. Return loss, VSWR and radiation pattern are obtained and analyzed using HFSS. Antenna is tested and measured results are also analyzed.
