새로 제안된 L자형 접이식 모노폴 안테나(LFMA)의 두 요소 어레이로 구성된 2GHz의 다중 입력 다중 출력(MIMO) 시스템을 위한 소형 내장 핸드셋 안테나가 다중 경로 전파 전파 환경에서 평가됩니다. 기본 특성, MEG(평균 유효 이득), 상관 관계 및 채널 용량을 분석하여 실제 사용 조건에서 핸드셋 MIMO 안테나로서의 성능이 크게 향상되었음을 확인했습니다. 또한 제안된 안테나의 유효성을 검증하기 위해 두 개의 PIFA(Planar Inversed-F Antenna) 요소로 구성된 배열 안테나의 성능과 비교했습니다. 결과는 제안된 LFMA 어레이를 PIFA 어레이의 44%에 해당하는 작은 크기로 사용함으로써 동등하거나 향상된 성능을 구현할 수 있음을 보여준다. LFMA 어레이는 PIFA 어레이와 비교하여 거의 동일한 대역폭과 향상된 격리를 제공하며 다중 경로 전파 전파 환경에서 충분히 낮은 상관 관계와 허용 가능한 유효 이득을 얻습니다. 또한, 특히 제안된 LFMA 어레이가 디스플레이 보기 모드로 기울어진 경우 PIFA 어레이보다 더 큰 채널 용량을 얻을 수 있으며, 또한 단일 입력에 비해 MIMO 전송을 사용하면 채널 용량이 거의 두 배 증가합니다. 단일 출력(SISO). 본 연구는 또한 제안된 안테나에 대해 MEG가 상관관계보다는 채널 용량에 더 많은 영향을 미친다는 것을 보여준다.

Abstract: A compact built-in handset antenna for multiple-input multiple-output (MIMO) system at 2 GHz, comprising two elements array of newly proposed L-shaped folded monopole antenna (LFMA), is evaluated under the multipath radio wave propagation environments. By analyzing the fundamental characteristics, mean effective gain (MEG), correlation, and channel capacity, the significant enhancement in the capability, as a handset MIMO antenna under practical use conditions, was confirmed. The performances were also compared to those of an array antenna comprising two planar inversed-F antenna (PIFA) elements in order to verify the effectiveness of the proposed antenna. The results show that the equivalent or improved performances can be realized, by using the proposed LFMA array with a compact size, taking only the volume of 44% of a PIFA array. The LFMA array provides almost the same bandwidth and enhanced isolation compared with a PIFA array, and the sufficiently low correlation and acceptable effective gain are obtained under the multipath radio wave propagation environments. In addition, a greater channel capacity than a PIFA array is achieved especially when the proposed LFMA array is inclined for the display-viewing mode, and moreover, an almost doubled increase in the channel capacity is obtained by using MIMO transmission compared with single-input single-output (SISO). This study also show that the MEG has much effects on the channel capacity, rather than the correlations, for the proposed antenna.
