Experimental Results of Spherical Arrays of Circular Waveguide and Microstrip Antennas

Arrays of circular waveguide and microstrip antennas on spherical surface are measured. The radiation pattern of a two experimental models of antenna arrays on spherical surface is obtained experimentally and is compared with theoretical patterns in order to verify theoretical results, without intention to improving the best radiation characteristics of a developed laboratory models. Arrays are analyzed using the spectral-domain approach and moment method. Measurements were not performed in a well-defined anechoic environment.
