Improved H-shaped Multiband MSA for DCS, WiMAX and WLAN Application with Enhanced Antenna Parameters
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 1.8268GHz, 2.6352GHz and 5.2840GHz are -38.62dB, -50.62dB and -19.48dB respectively. It is obtained that the designed antenna offers enhanced value of S11 and VSWR less than 1.24. Ansoft HFSS v11 is used for simulation of this patch antenna.
