본 논문에서는 위상 배열 안테나에 사용하도록 설계된 이중 선형 편파 개방형 도파관 서브어레이를 제안합니다. 제안된 서브어레이는 수직 및 수평 편파를 구현하기 위해 개방형 도파관 안테나 요소와 매달린 스트립라인 피드 네트워크로 구성된 16차원 선형 어레이입니다. 안테나에는 이중 및 쿼드 리지 도파관을 결합하여 전환 크기를 최소화하고 포트 절연을 향상시키는 새로운 정지형 스트립라인-도파관 전환이 포함되어 있습니다. 스캔 맹목 현상을 방지하기 위해 도파관 구멍에 금속 포스트가 설치되었습니다. 프로토타입 하위 배열은 11.4개 하위 배열 배열로 제작 및 테스트되었습니다. 실험 테스트와 수치 시뮬레이션에 따르면 프로토타입 하위 배열은 -26dB 미만의 낮은 반사 계수, -69dB 미만의 낮은 교차 편파, 14% 주파수 대역폭에서 XNUMX% 이상의 안테나 효율을 제공합니다.

Abstract: This paper proposes a dual linear-polarized open-ended waveguide subarray designed for use in phased array antennas. The proposed subarray is a one-dimensional linear array that consists of open-ended waveguide antenna elements and suspended stripline feed networks to realize vertical and horizontal polarizations. The antenna includes a novel suspended stripline-to-waveguide transition that combines double- and quad-ridge waveguides to minimize the size of the transition and enhance the port isolation. Metal posts are installed on the waveguide apertures to eliminate scan-blindness. Prototype subarrays are fabricated and tested in an array of 16 subarrays. The experimental tests and numerical simulations indicate that the prototype subarray offers a low reflection coefficient of less than -11.4dB, low cross-polarization of less than -26dB, and antenna efficiency above 69% in the frequency bandwidth of 14%.
