Abstract

In this thesis, radiation performance of a ground radiation antenna using magnetic coupling structure is compared with a conventional planar inverted-F antenna (PIFA) in terms of impedance bandwidth and radiation efficiency. The size of the proposed ground radiation antenna is 5 ｘ 10 mm2, reduced up to approximately 50% while the impedance bandwidth is obtained as 560 MHz (2174~2734MHz), improved by approximately 300% compared to the PIFA. The size of the ground plane is 50 ｘ 20 mm2, intended for USB dongle and headset applications.
