새로운 휴대폰용 접이식 루프 안테나 분석과 휴대폰 안테나의 고급 설계 개념을 설명합니다. 본 논문에서 제시된 설계 개념은 (1) 작은 크기이면서 (2) 신체 효과로 인한 안테나 성능 저하를 완화할 수 있는 능력, (3) 안테나에서 SAR 값을 줄이는 능력 등 핸드셋 안테나의 가장 중요한 요구 사항을 충족합니다. (4) 로우 프로파일 및 (5) 경량과 같은 핸드셋 안테나에 대한 필수 요구 사항 외에도 핸드셋 통화 위치에 사람 머리가 있습니다. 적용된 기술은 이 안테나를 (a) 안테나를 작게 만드는 기본 개념을 적용한 대표적인 통합 구조와 (b) 요구 사항을 충족하는 데 매우 효과적인 것으로 입증된 균형 잡힌 구조로 만드는 것입니다(2). 그리고 (3). 안테나는 본질적으로 XNUMX선 전송선으로, 약 XNUMX/XNUMX 파장으로 접혀 반파장 접힌 쌍극자를 형성하지만 XNUMX파장 루프처럼 보입니다. 불균형 라인이 공급되는 것처럼 실제로 균형 잡힌 구조를 가지고 있지 않습니다. 그러나 안테나 구조 자체는 평형 안테나 시스템에서처럼 급전선의 불균형 전류 흐름을 제거할 수 있습니다. 이론적 분석과 실험적 분석이 모두 제시되었으며 안테나의 유용성이 논의되었습니다. 본 논문은 미래를 향한 휴대폰 안테나 개발에 적용될 첨단 기술과 설계 개념을 제시할 수 있다.

Abstract: Analysis of a novel folded loop antenna for handset is described along with the advanced design concept for handset antennas. The design concept shown in this paper meets the foremost requirement for handset antennas such as (1) small size and yet (2) has capability of mitigating degradation of antenna performance due to the body effect, and (3) of reducing SAR value in the human head at the handset talk position, in addition to the indispensable requirements for handset antennas such as (4) low profile, and (5) light weight. The technology applied is to make this antenna (a) an integrated structure, which is a typical application of the fundamental concept of making antennas small and (b) a balanced structure which has been proved to be very effective to satisfy the requirements (2) and (3). The antenna is essentially a two-wire transmission line, folded at about a quarter-wavelength to form a half-wave folded dipole, and yet appears to be a loop of one-wavelength. It does not have really a balanced structure, as is fed with an unbalanced line; however, the antenna structure itself can eliminate the unbalanced current flow on the feed line as in the balanced antenna system. Both theoretical and experimental analyses have been shown and the usefulness of the antenna is discussed. This paper may suggest the advanced technology and design concept that will be applied to the development of handset antennas toward the future.
