This article first antenna, microstrip theory, the circular polarization technology, the theoretical discussion, in this based on the microstrip antenna of circular polarization method - corner square microstrip antenna, and has done a design simulation , and then do the design and further research to improve and eventually get a resonant frequency (S11 reflection coefficient corresponding to the minimum frequency) for the 1.5GHz and 1.43GHz, the frequency of circular polarization for the 1.46GHz, S11 is less than -10dB relative bandwidth, the VSWR is less than 2 is about 8.8% relative bandwidth, axial ratio less than 3dB relative bandwidth of about 2.2% of the right circular polarization microstrip antenna design case, which proved very good the circular polarization microstrip antenna theory, also fully confirmed by a square corner design is a practical program, and select the appropriate regulation of sticks is indeed able to improve the performance of the antenna.

Second, proceeding with the fact thatthe constructing vector wave functions of conventional circular cylindrical and sphericalvector wave functions are linear independent solutions to the electromagnetic field waveequations in biisotropic medium,spectral impedance boundary conditions are proposed forinfinitely long perfectly conducting circular cylinder and sphere coated with biisotropic media,respectively,which generalize the applicable range of planar structures and are suitable toanalyze the electromagnetic problems involving their counterpart structures.
