摘要
Abstract
The traditional transmissive air-fed array suffers from the drawback of low power capacity and cannot be directly applied in the high-power microwave field.The existing high-power air-fed array layouts are not flexible enough and have slow beam scanning speeds,which cannot fully exploit the advantages of phased arrays in system integration.This article proposes and designs a new type of spiral radiation unit using spatial feed,and constructs a transmissive air-fed spiral array antenna.By controlling the rotation of individual spirals,two-dimensional beam scanning can be achieved,making the design more flexible and adaptable to the actual application requirements,in line with the compact and modular development trend of high-power microwave antennas.An array consisting of 324 units was simulated and designed.The numerical simulation results show that the unit S11≤-20 dB,power capacity is 0.35 MW,array aperture efficiency is 0.68,and it can scan within the range of±45°,with a maximum gain reduction of 3 dB.关键词
