Antena tatasusunan 16×16 slot suapan korporat W dengan aras sidelobe rendah direka dan direka. Unit asas tatasusunan ialah subarray 2×2-slot bulatan dengan rongga persegi langkah dan menggunakan pandu gelombang E-satah sebagai garis suapan. Kaedah yang cekap untuk mereka bentuk nisbah pemisahan kuasa yang tidak sama rata tetapi fasa yang sama (UPEP) E-plane waveguide T-junction (ET) dicadangkan untuk membina rangkaian suapan tirus kuasa 1 hingga 64, yang merupakan bahagian penting untuk direalisasikan tahap sidelobe rendah. Seluruh tatasusunan dibuat dengan aluminium melalui pengilangan dan diikat oleh proses pematerian vakum. Keputusan yang diukur menunjukkan bahawa tatasusunan boleh mencapai lebar jalur 7.2% dengan VSWR<1.5 dan tahap sidelobe holistik lebih rendah daripada -23.5dB dalam satah E dan satah H daripada 89GHz ~ 95.8GHz. Keuntungan yang diukur adalah lebih tinggi daripada 31.7dBi berbanding jalur kerja dengan kecekapan antena lebih baik daripada 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%.
