A coupled-fed microstrip antenna for 4G mobile system is presented. The PIFA antenna operates at 704-960 MHz and 1710-2170 to cover frequency bands of LTE 700/850/900/1800/1900/2100(Tx/Rx). An L-shaped coupled-fed structure, an inductor and a shorting line to ground are compactly designed together to create dual resonances at both loW and high bands to achieve wide bandwidth and better impedance matching. The overall dimension of mobile system is 58X119X1.2mm3 and the antenna size occupies area of 58X16mm2.
