반사 위상을 제어하기 위해 버섯형 메타표면 반사판을 위한 인터디지털 및 다중 비아 구조를 갖춘 새로운 패치 요소 모양이 제안되었습니다. 인터디지털 구조는 인터디지털 핑거의 깊이를 변경하여 넓은 반사 위상 범위를 제공합니다. 또한 멀티 비아 구조는 +180° 부근과 같은 더 높은 포지티브 반사 위상을 제공합니다. 360°의 충분한 반사 위상 범위와 낮은 편광 의존 특성은 전자기장 시뮬레이션을 통해 확인할 수 있습니다. 수직 입사 평면파에 대한 메타표면 반사기를 설계했습니다. 원하는 반사 각도와 반사된 빔의 날카로운 원거리장 패턴을 시뮬레이션 결과에서 확인할 수 있었습니다. 실험을 위한 프로토타입 반사경은 반사경 안테나의 XNUMX차 반사경 설계와 동일한 방식으로 설계되어야 합니다. 구체적으로, 입사파 위상을 이용한 광선 추적 방법을 기반으로 한 반사경 설계 방법이 프로토타입에 제안되었다. 송신 안테나(TX)와 프로토타입 메타표면 반사기로 구성된 반사기 안테나에 대한 실험적 방사 패턴은 시뮬레이션된 방사 패턴과 유사했습니다. 제안된 구조와 설계방법의 유효성은 이러한 시뮬레이션과 실험 결과를 통해 확인할 수 있었다.

Abstract: The novel patch element shapes with the interdigital and multi-via structures for mushroom-type metasurface reflectors are proposed for controlling the reflection phases. The interdigital structure provides a wide reflection phase range by changing the depth of the interdigital fingers. In addition, the multi-via structure provides the higher positive reflection phases such as near +180°. The sufficient reflection phase range of 360° and the low polarization dependent properties could be confirmed by the electromagnetic field simulation. The metasurface reflector for the normal incident plane wave was designed. The desired reflection angles and sharp far field patterns of the reflected beams could be confirmed in the simulation results. The prototype reflectors for the experiments should be designed in the same way as the primary reflector design of the reflector antenna. Specifically, the reflector design method based on the ray tracing method using the incident wave phase was proposed for the prototype. The experimental radiation pattern for the reflector antenna composed of the transmitting antenna (TX) and the prototype metasurface reflector was similar to the simulated radiation pattern. The effectiveness of the proposed structures and their design methods could be confirmed by these simulation and experiment results.
