Improved H-shaped Multiband MSA for DCS, WiMAX and WLAN Application with Enhanced Antenna Parameters

摘要

Multi band H shaped MSA is presented here. This antenna is suitable for DCS, WiMAX and WLAN application. FR-4 epoxy substrate is used on which H shaped slot is cut by etching technique. This structure radiates for DCS (1.71-1.88) GHz, low band WiMAX (2.50-2.69) GHz and WLAN (5.15-5.35) GHz. The return loss obtained at 1.8268 GHz, 2.6352 GHz and 5.2840 GHz are -38.62 dB, -50.62 dB and -19.48 dB respectively. It is obtained that the designed antenna offers enhanced value of S_(11)and VSWR less than 1.24. Ansoft HFSS v11 is used for simulation of this patch antenna.
