Abstract

This paper presents the designing of base station antenna arrays useful for mobile communications. The whole structure involves three antenna arrays that cover three adjacent cells of the service area. The use of 120° corner reflectors is proposed for minimizing the interference between cells. Initially, the design suggests Chebyshev excitation distribution on each antenna array and equal interelement distances in order to achieve a radiation pattern with low side lobe level. The use of uniform excitation distribution and unequal interelement distances is suggested as an alternative solution for low side lobe level. The distances between the elements are calculated by combining an iterative perturbation process and the orthogonal method. Optimized geometries as well as radiation patterns, which meet the base station requirements, are given.
