Abstract

Ground radiation antenna in mobile devices is becoming an issue for satisfying both miniaturization and high performance. Ground radiation antenna controls the characteristic mode of the ground plane and couples this mode with the ground radiation antenna, thereby having good radiation performance. In this paper, the characteristic mode theory and applications of ground radiation antenna will be introduced. The operating mechanism of single band, wideband and dual-band ground radiation antennas are studied.

최근 휴대 단말기 안테나의 소형화와 고성능화에 대한 요구가 증대되고 있다. 단말기의 그라운드는 좋은 방사체로, 이를 활용한 휴대 단말기 그라운드 방사 안테나는 안테나의 소형화 및 고성능화를 동시에 만족시킬 수 있기 때문에, 많은 관심을 받고 있다. 그라운드 방사 안테나는 단말기 그라운드의 특성 모드를 제어하고, 이를 안테나와 결합하여 그라운드를 방사체로 활용하기 때문에 그 방사 성능이 우수하다. 본 논문에서는 그라운드의 특성 모드 이론에 대해 설명하고, 이를 활용한 그라운드 방사 안테나의 다양한 적용 예시를 단일 대역, 광대역 및 이중 대역 그라운드 방사 안테나로 나누어 소개하고자 한다.
