본 논문에서는 28GHz 대역의 5G 이동 통신 중계용 혼 안테나의 방사 패턴, 반사손실 등의 성능을 고려하여 중계용 안테나를 설계하였다. 안테나 소자를 위상 배열하여 5G 이동통신 중계기용 혼 Array를 설계하고 성능을 분석하였다. 밀리미터파 대역 통신에서는 기존의 WCDMA(3G), LTE(4G)와 달리 송수신 간의 높은 경로 손실이 발생한다. 5G 밀리미터파 혼 안테나 설계에서는 안테나의 이득, 대역폭뿐만 아니라, 안테나 소자 간 격리도, 이득 등의 안테나 성능을 추가로 고려해야 한다. 28GHz 대역의 단일 혼 안테나(1×1)와 배열 혼 안테나(2×4)의 안테나 이득은 각각 약 10.44dBi와 19.58dBi, 반사손실도 -18dB 이하의 특성을 되도록 설계하여 측정 결과로부터 구현의 타당함을 입증하였고, 5G 이동 통신 중계 시스템에 응용에 적합함을 보였다.

In this paper, the relay antenna was designed in consideration of the performance of the 28GHz band 5G mobile communication relay horn antenna, such as radiation pattern and return loss. A horn array for 5G mobile communication repeater was designed by arranging the antenna elements in phase, and the performance was analyzed. Unlike conventional WCDMA (3G) and LTE (4G), in millimeter wave band communication, high path loss occurs between transmission and reception. In the design of a 5G millimeter wave horn antenna, antenna performance such as isolation and gain between antenna elements as well as gain and bandwidth of the antenna must be additionally considered. The antenna gain of the single horn antenna (1×1) and the array horn antenna (2×4) in the 28GHz band is about 10.44d Bi and 19.58dBi, respectively, and the return loss is designed to be less than -18dB. It has proven its validity and has been shown to be suitable for application to 5G mobile communication relay system.
