Uma antena de matriz de 16 × 16 slots de alimentação corporativa de banda W com baixo nível de lóbulo lateral é projetada e fabricada. A unidade básica do array é um subarray de slot circular 2 × 2 com cavidades quadradas escalonadas e usa um guia de ondas de plano E como linha de alimentação. Um método eficiente para projetar uma junção T (ET) de guia de ondas de plano E de relação de divisão de potência desigual, mas de fase igual (UPEP) é proposto para a construção de uma rede de alimentação com redução de potência de 1 a 64, que é a parte crítica para realizar baixo nível do lóbulo lateral. Todo o conjunto é fabricado em alumínio por fresagem e colado pelo processo de brasagem a vácuo. Os resultados medidos demonstram que o array pode atingir uma largura de banda de 7.2% com VSWR <1.5 e níveis holísticos de lóbulo lateral inferiores a -23.5dB no plano E e no plano H de 89 GHz a 95.8 GHz. O ganho medido é superior a 31.7dBi na banda de trabalho com eficiência da antena melhor que 67.5%.

Abstract: A W-band corporate-feed 16×16-slot array antenna with low sidelobe level is designed and fabricated. The basic unit of the array is a 2×2-circular-slot subarray with step square cavities and uses an E-plane waveguide as the feeding line. An efficient method to design an unequal power-splitting ratio but equal phase (UPEP) E-plane waveguide T-junction (E-T) is proposed for constructing a 1-to-64 power-tapering feed network, which is the critical part to realize low sidelobe level. The whole array is fabricated with aluminum by milling and bonded by the vacuum brazing process. The measured results demonstrate that the array can achieve a 7.2% bandwidth with VSWR<1.5 and holistic sidelobe levels lower than -23.5dB in E-plane and H-plane from 89GHz ∼ 95.8GHz. The measured gain is higher than 31.7dBi over the working band with the antenna efficiency better than 67.5%.
