초록

본 논문은 LTE Band 5(824~894 MHz)에서 모노폴 타입과 슬롯 타입을 적용하여 저상관도를 갖는 MIMO(Multiple-Input Multiple-Output) 안테나 설계를 제안한다. 두 안테나 사이의 상관도 성능을 향상시키기 위하여 설치되는 그라운드의 특성 모드 이론에 기초하여 안테나의 형태를 서로 다르게 제작하였다. 논문에서 제안하는 MIMO 안테나는 각각 PIFA와 슬롯 안테나로 구성되어 있고, 두 개 모두 PIFA(Planar Inverted F Antenna)로 제작한 경우와 상관도 성능을 비교하였다. 서로 다른 구조의 두 개의 PIFA 타입으로 제작된 MIMO 안테나의 평균 상관 계수는 0.71로 매우 높았으나, 본 논문에서 제안된 MIMO 안테나는 0.17로 상관도 특성이 매우 낮아짐을 확인할 수 있었다.

In this paper, MIMO antenna with low correlation for LTE band 5(824~894 MHz) was designed by adopting monopole antenna and slot antenna. Based on ground characteristic mode theory, MIMO antenna was designed using different types of antennas for enhancement of correlation. MIMO antenna using PIFA and slot type antennas is proposed and correlation coefficient was compared with MIMO antenna using two PIFAs. Average correlation coefficient of MIMO antenna using two PIFAs was 0.71 but the proposed MIMO antenna had very low correlation coefficient of 0.17.
