Abstract :
A new wideband, very low profile (3 mm), PIFA antenna is proposed. It utilizes two collinear feeds, ground plane slots and modified top radiating plate to reduce the mutual coupling between the feeds and improve the impedance matching. The proposed antenna has a 10-dB impedance bandwidth from 2.25 to 3.2 GHz or a fractional bandwidth of 35 %. It covers several important wireless applications such as 2.4 GHz WLAN, bluetooth, four LTE bands (bands 7, 38, 40 and 41) and S-DMB band 2.63-2.655 GHz. Both simulated and measured results are presented to quantify and validate the antenna performance. It is demonstrated that this new antenna is an excellent candidate for mobile diversity/MIMO applications.
