| Abstract: | The procedures for designing a waveguide aperture antenna are presented.A waveguide aperture antenna working in X-band is designed.The aperture of antenna,number of waveguide,and parameters of aperture including number,width and location are calculated.A wide-arm coupling resonant aperture magic T comparator with half-height waveguide is designed,based on which the design of the antenna is finished.Simulation results indicate that gain of the sum beam is 28.9 dB and the first side lobe is-22.2 dB at 12 GHz.The antenna can attain good parameters such as sum and subtract pattern,voltage stand wave ratio and gain. |
