플랫폼에 장착된 소형 안테나는 유전 손실과 전도성 손실을 증가시키고 방사 효율을 감소시킵니다. 본 논문에서는 특성 모드 분석을 통해 플랫폼 탑재형 소형 안테나의 방사 효율을 향상시키는 새로운 안테나 설계 방법을 제안한다. 제안된 방법은 모드 가중치 계수(MWC)와 극소 쌍극자의 매핑을 사용하고 역 F 안테나에 의해 여기되는 플랫폼인 100mm × 55mm × 23mm의 금속 케이스를 평가합니다. 시뮬레이션 및 측정 결과, 단일 안테나의 5%에 비해 전체 시스템에서 2.5%의 방사 효율이 향상되는 것으로 나타났습니다.

Abstract: Platform-mounted small antennas increase dielectric loss and conductive loss and decrease the radiation efficiency. This paper proposes a novel antenna design method to improve radiation efficiency for platform-mounted small antennas by characteristic mode analysis. The proposed method uses mapping of modal weighting coefficient (MWC) and infinitesimal dipole and evaluate the metal casing with 100mm × 55mm × 23mm as a platform excited by an inverted-F antenna. The simulation and measurement results show that the radiation efficiency of 5% is improved with the whole system from 2.5% of the single antenna.
