Abstract

A phased-array antenna design for 5G base station applications in the 3.4–3.8 GHz band is presented. End-fire bow-tie antenna elements are used to maximize the available space for electronics that can be placed closely to the antenna elements in the array. Infinite array simulations of a phased-array bow-tie antenna show that a −10 dB reflection coefficient can be achieved in the whole 3.4–3.8 GHz band for elevation scan angles up to 45° and all azimuth scan angles. Simulation and measurement results of a 4×4 bow-tie phased-array demonstrator antenna show good performance in the 3.4–3.8 GHz band for most elevation scan angles up to 45°.
