Diffraction Research Based on the Small Aperture Antenna Design
With the diffraction of small aperture antennas considered as the background,the general diffraction integral formula of Fraunhofer is derived,and the calculation method of the single fast Fourier transform of Fraunhofer integral is provided.Then,the diffraction field of the basic graph is calculated,and the calculation idea of polygons and polygonal stars is deduced.Finally,the laws of diffraction phenomena and the results are obtained through experiments and Matlab simulation.The diffraction laws can be applied to the study of aperture in the design of small aperture antennas.
