Abstract
A miniaturized Planar Inverted Antenna F-Antenna for LTE700M service band is presented. The main radiator of PIFA antenna is been folded into three radiating arm which provide optimized dimensions. Then, stair-shaped geometry have been used in order enhance impedance bandwidth for both lower band and higher band. Finally, the size of the finite ground is gradually reduced to achieve optimum size reductions. In the experimental results, the antenna achieves lower band impedance bandwidth between 725 MHz and 1.18 GHz at 6 dB return loss. At upper band, the antenna covers bandwidth between 2.33 and 3.82 GHz at 10 dB return loss. The final antenna #2 achieved reduction in overall dimension by 46.6 % in length, 33.7 % in width, and 5.19 % in height as compared to its reference antenna. Hence, this miniaturized size of proposed PIFA antenna is a promising candidate for several wireless services such as LTE700, GSM850/900, WLAN2.45G and WiMAX3.5G.
