본 논문에서는 실내 무선랜 환경에서 인접한 동작 주파수 스펙트럼을 가진 외부 간섭신호를 차단하기 위해 Wi-Fi 6E 시스템에적용할 수 있는 이중대역 차단 주파수 선택표면을 설계하였다. 제안한 주파수 선택적 표면 구조는 2.4GHz 대역과 6GHz 대역에서주파수 차단 특성을 가지며, 변형된 교차 쌍극자 구조와 단위 구조간 서로 맞물린 퍼즐 형태를 통해 구현되었다. 제안한 구조는 입사각과 편파에 대해 안정적인 주파수 응답 특성을 갖도록 설계되었으며, 제작 및 실험으로부터 0°~45°의 입사파에 대해 시뮬레이션에서 얻은 결과와 잘 일치하는 것을 확인하였다.
Abstract
In this paper, a dual-band stopband frequency selective surface that can be applied to Wi-Fi 6E systems isdesigned to block external interfering signals with adjacent operating frequency spectrum in indoor wireless LANenvironments. The proposed frequency selective surface structure has frequency blocking characteristics in the2.4GHz and 6GHz bands, and is realized through a modified crossed dipole structure and an interlocking puzzleform between unit structures. The proposed structure is designed to have stable frequency response characteristicswith respect to incident angle and polarization, and the experimental results show good agreement with thesimulation results for incident waves from 0° to 45°.
