Abstract

In this paper, we propose the structure of a dual polarized system for a wireless communication. The proposed dual polarized antenna is formed by one vertical antenna and two horizontal antennas that are orthogonal to each other. Vertical and horizontal polarized antennas transmit different signals, but two orthogonal horizontal polarized antennas transmit the same data signals. So, the signals of the proposed dual polarized system construct two dual-polarization planes. And, only one dual-polarization plane with a large signal power is selected at the side of a receiver. The simulation results show that the proposed dual polarized system could obtain a higher capacity compared to an ordinary $2{\times}2$ MIMO (Multi-input Multi-output) system.

본 논문에서는 고용량 전송을 위한 무선통신시스템의 이중 편파 송수신 안테나 구조를 제안한다. 제안된 이중편파 시스템은 송수신기 모두 서로 직교하는 하나의 수직 편파 안테나와 두 개의 수평 안테나로 구성 된다. 제안된 시스템의 수직 편파 안테나와 수평 편파 안테나는 서로 다른 데이터 신호를 전송하지만, 서로 직교하는 두 수평 편파 안테나는 동일한 데이터 신호를 전송한다. 이에, 제안된 이중 편파 신호는 두 개의 이중 편파 평면을 구성한다. 그리고 수신측에서 수신 신호전력이 큰 이중 편파 평면이 선택된다. 모의실험을 통해 제안된 이중 편파 시스템이 단일 편파를 사용하는 $2{\times}2$ MIMO 시스템 보다 채널 용량 이득을 얻을 수 있음을 확인하였다.
