Method and Device for Analysis of Circular Patch Antenna fed by Coaxial-Line

摘要

The present invention relates to an analysis method and apparatus of the circular patch antenna is fed by a coaxial line. ; To this end, the present invention is, by using a Fourier transform calculation of the field expression of an open area on the circular patches, circular patches are coaxial lines and have the same center point, map the coaxial cable feeding zone cone foam then, where the graft relative to the cone foam mapped value to calculate the field Sean expression of coaxial cable feeder area using a clean and eigenfunction expansion method. And, through the simultaneous equations to calculate the discrete mode for using the coefficient field expression of an open area of the field expression and coaxial feeding area, by using a circular patch antenna to provide an analysis method for calculating the impedance and the radiation pattern The. ; According to the present invention, according to a strict interpretation of the circular patch antenna that is powered by a coaxial line is off-center becomes possible, a small circular patch antenna analysis method through a physical interpretation method has a computational complexity Using this application you can expect a wide range of possible effects, such as antenna design and production.
