A simple and miniaturized S shaped wide band microstrip patch antenna is presented and measured in this paper. Antenna is developed using a FR4 epoxy (dielectric constant = 4.4) substrate on a Split or partial ground. The proposed antenna has a wide band response and useful in wireless and other applications. The antenna can be used in Digital multimedia broadcasting DMB (frequency range: 2.58 GHz – 2.88 GHz) as well as LTE 2500 MHz. The presented ‘S’ shaped antenna has been designed, simulated and measured using high frequency structural simulator (HFSS) v15 Software and microwave antenna testing unit. The results are attractive with VSWR< 2 for the required frequencies. The wide band can be seen from 3.38 GHz to 7.3 GHz which can be useful for WLAN/WiMAX etc. The Return loss and radiation patterns are observed to be omnidirectional with moderate gain. Reduction in size of the antenna is obtained by taking slots in the patch and split or partial ground concept. The overall reduction in size of the antenna is around 70%. The simulated and measured results show that the antenna is suitable for DMB, LTE, WLAN, WiMax and satellite uplink applications. The dimension of the proposed antenna is 30 mm×34 mm×1.6 mm.
