Abstract :
A planar inverted-F antenna (PIFA) is presented, which has a dual-resonance feed structure that enhances impedance bandwidth considerably. The proposed antenna fully covers LTE13/GSM850/GSM900 without significant modification of the antenna element fabricated in a small ground clearance. The antenna´s impedance bandwidth under VSWR = 3:1 is 733-974 MHz, with a good realised efficiency.
