PIFA with dual-resonance feed structure for enhancement of impedance bandwidth

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...

Description
Summary: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.
