A waveguide slot planar array antenna with terminal gap structure
In order to reduce manufacturing difficulty,and to improve environmental adaptability of waveguide slot planar array antenna,a waveguide slot antenna array with terminal gap structure was provided,and the influence of waveguide terminal gap structure on input impedance of radiated waveguide was analyzed.Basing on those analysis,the design method of waveguide slot antenna array was provided and a Ka band array was simulated with 22×4 elements.Simulation results show that the waveguide slot antenna array with terminal gap structure has equivalent electronic performance to traditional waveguide slot antenna array.Waveguide slot antenna array with terminal gap structure has advantage of production and acclimatization.
