Application of the Plane Wave Synthesis Technique Based on the Least Square Method in Antenna Measurements
A novel plane wave synthesis technique based on the least square method is presented and its application in antenna measurements is studied by the method of computer simulation. With the linear array made up of the infinitely long current filament as the theoretical model of plane wave synthesis, and with the uniform linear array made up of half-wavelength dipole elements as the antenna under test, the receiving patterns of which under the illumination of the quasi-plane waves synthesized by the presented plane wave synthesis technique and the traditional plane wave synthesis technique respectively are calculated and compared with the theoretical receiving pattern under the illumination of ideal plane wave. The calculation results show that in the case that the corresponding parameters remain unchanged, the receiving pattern obtained by the presented plane wave synthesis technique agrees with the theoretical receiving pattern better than the receiving pattern obtained by the traditional plane wave synthesis technique, which proves the correctness and validity of the application of the presented plane wave synthesis technique in antenna measurements.
