Abstract :
In this paper a switched beam 4×1 linear antenna array is presented with a 4×4 butler matrix feed. For wideband operation aperture coupled antenna elements are used in the array whereas wideband hybrid couplers and cross couplers are used in the butler matrix feed. Design and simulation was carried out in IE3D® software, considering a Rogers RO3006 substrate. The array is designed to cover LTE bands at 2.3 & 2.6 GHz as well as the 2.4 GHz ISM band. The performance parameters from simulation are presented and analyzed. A total of 1:1.43 VSWR, bandwidth of 520 MHz is obtained with gain of 11 dB, directivity of ~12.5 dBi and efficiency greater than 70%. The radiation beam directions in azimuth are obtained at +15°, -15°, +45° and -45° for respective input port.
