Radiation Pattern Reconstruction Techniques for Antenna Measurement Using Chebyshev Polynomials

A new method of antenna radiation pattern reconstruction using Chebyshev polynomials was presented in this paper. The analysis starts from the data measured in the frequency domain, and it corresponds to a direct propagating between two antennas and reflected propagating waves from the copper plate. The accuracy of this technique is evaluated at the frequency of 3.35㎓ by the anechoic conditions. As a result, the Chebyshev method shows us a good performance in the E-plane in the range of -70 ° ~0 °
