Design of High Gain Cosecant Beam-Forming Array Antenna

Abstract

A cosecant shaped-beam array antenna with extremely high gain is proposed. This article utilizes an effective synthesis method to design a high gain cosecant beam-forming array antenna. A program for Synthesis of cosecant beam-forming is compiled, using Perturbation alternating projections method for Pattern Synthesis. By employing this method, a huge cosecant beam-forming antenna array of $128 \times 16$ units is proposed, which provides an extremely high gain of 42.1dB. This design of given both shaped amplitude and phase of each antenna unit, can be controlled to produce a squared cosecant beam. Absence of amplitude and phase shift distribution graphs, processes of design is illustrated in detail, which generates the shaped pattern. A proposed antenna is designed at the frequency band of 1.44-1.74GHz, and simulated by full-wave analyzer HFSS software to validate the proposed method.
