Abstract

We design a displaced-axis Gregorian dual antenna in the form of a metal reflectarray antenna for millimeter wave region, W-band. Unlike a reflectarray composed of printed patch antennas on a dielectric substrate, metallic rectangular waveguide unit-cells are proposed to avoid the loss of substrate and take an advantage of ease of typical metal machining fabrication. In this paper, the radiation characteristics of constructed metal reflectarray antennas show ultra high-gain antenna over 50 dBi at a target frequency in W-band. The experimental measurements are conducted in millimeter-wave compact range antenna measurement system.

밀리미터파 대역인 W-대역에서 초고이득 반사배열안테나를 구현하기 위하여 이중 반사판형태 중 주 반사판으로 향하는 전파가 급전부로 되돌아오지 않도록 하여 안테나의 효율 및 이득 특성을 크게 개선한 축이동 그레고리안 안테나를 금속 반사배열안테나 형태로 구현하였다. 금속 반사배열안테나의 경우, 유전체를 이용한 반사배열의 안테나와 달리 기판에 의한 손실이 없으며, 금속가공만으로 제작될 수 있는 제작의 편의성을 갖고 있다. 본 논문에서는 사각형 금속 개구의 배열을 이용하여 50 dBi 이상의 초고이득 축이동 금속 반사배열안테나를 설계하고, 일반적인 기계 가공을 이용하여 안테나를 제작하였으며, 제작된 안테나는 밀리미터파 컴팩트 레인지 안테나 측정시스템을 이용하여 검증하였다.
