초록

본 논문에서는 아이솔레이션 에이드를 사용하여 격리도를 향상시킨 무선랜용 MIMO안테나를 설계하였다. IEEE 802.11.n의 무선랜대역인 2.4GHz대역과 5GHz대역에서 사용이 가능한 PIFA를 안테나 프레임과 접지면을 기준으로 대칭으로 배치하였다. 두 안테나 사이에 아이솔레이션 에이드를 삽입하여 2.4GHz대역의 격리도를 최대 5dB향상시켰고, 5GHz대역의 격리도를 최대 7dB향상 시켰다. 제안된 안테나의 전체효율은 60%이상이며, 계산된 ECC(Envelope Correlation Coefficient)는 0.1이하이다.

In this paper we design MIMO antenna with high isolation between antennas by using an isolation aid for WLAN. Two dual-band PIFAs which operates IEEE 802.11n are arranged symmetrically along the central axis of antenna frame and ground plane. By inserting an isolation aid between two PIFAs the isolation is improved maximum 5dB and 7dB for 2.4GHz band and 5GHz band respectively. Total efficiency is above 60%. ECC is below 0.1.
