摘要：
In this paper a Switched beam 4x1 linear antenna array is presented with a 4x4 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 Simulations are carried out in IE3D software considering a low cost FR4 substrate. The array is designed to cover LTE bands at 2.3 & 2.6GHz as well as the 2.4GHz ISM band. The performance parameters from simulation and measurements are presented and analyzed. A total 1: 1.3 VSWR bandwidth of 400MHz is obtained with gain between 6-7.5dB, directivity of similar to 12dBi and Efficiency greater than 30%. The radiation beam directions in azimuth are obtained at +15, -15, +45 and -45(0) for respective input port.
