Abstract
This paper presents the optimum design of a 4 × 4 planar Butler matrix array as a key component of a switched beam smart antenna system operating at 10 GHz for X band applications. In 4 × 4 Butler matrix, four input ports are used for the input signal connections and four output ports can be connected to an array of four micro-strip edge feed patch antennas to form the beamforming network. Such a network is capable of production of four orthogonal uniform beams (at −50°, −10°, 10° and 50°) with effective coverage over 120°, when feed with electromagnetic signals. Conception details, and simulation results are also given for the components (hybrid coupler, crossover, phase shifter) used to implement the matrix. Finally, the simulation results using Ansoft HFSS show a great improvement of Gain and HPBW of the four generated orthogonal beams.
