Abstract

In this paper, a technique for optimizing the sub-array system structure that can minimize the side lobe level of the phased-array antenna is proposed. Optimization of the proposed array antenna structure is to adjust the spacing between sub-arrays and sub-arrays by using a hexagonal array structure of one sub-array and a hexagonal sub-array for six hexagonal arrays, and thus the entire phased array antenna system of the radiation pattern was optimized. Compared to the 2-dimensional planar antenna system, the proposed technique maintains a gain of 24.3 dBi and a half-power beam-width of 8.46 degrees without change, and only reduces -3.4 dB and -6.5 dB in the x-axis and y-axis directions, respectively.

본 논문에서는 위상배열안테나의 부엽레벨을 최소화할 수 있는 부배열 시스템 구조의 최적화에 관한 기술을 제안하였다. 제안된 배열안테나 구조의 최적화는 6개의 육각배열을 한 개의 부배열과 육각 부배열의 육각형 배열 구조를 이용하여, 부배열의 배열간격과 부배열 사이의 배열 간격을 조절하여, 전체 위상배열안테나 시스템의 방사패턴을 최적화하였다. 제안된 기술은 2차원 평명배열안테나 시스템에 비하여, 24.3 dBi의 이득과 8.46도의 반치각은 변화없이 유지하며, 오직 x축과 y축 방향으로 각각 -3.4 dB와 -6.5 dB를 감소시켰다.
