摘要
Abstract
In order to realize the beamforming performance of the search radar cosecant squared,a Ω-shaped waveguide slot array beamforming antenna is designed.The antenna adopts a Ω-shaped folding structure and gap offset to achieve phase and amplitude modu-lation,and realizes the cosecant square beamforming of the array.Through electromagnetic simulation calculation,the optimal structural parameters of the antenna are finally determined,and the physical processing and measurement are carried out.Measured results show that in the frequency range of 16.4～16.6 GHz,the voltage standing wave ratio of the array antenna is less than1.25,and the Gain of the array antenna is higher than 15.4 dBi,these measured results have good consistency with the simulation results.The antenna pro-vides the characteristics of high power,high gain and low profile,can be used as a unit for beamforming array antennas.The proposed beamforming method of the waveguide slot array beamforming antenna designed in this paper reduces the difference between the theoret-ical value and the design value in the beamforming range,so that the design of the waveguide slot antenna beamforming is no longer lim-ited by the amplitude and phase control of the slot.So it can be applied to a variety of beamforming occasions.关键词
