Design methodology for the multi-beam phased array of antennas with relatively arbitrary coverage sector

This paper presents the design methodology of multi-beam phased array of antennas that may provide high gain and narrow beam radiation patterns within a desired coverage range. The advantages of high energy efficiency in the coverage area provide the flexibility of applications in various area such as wireless power transmission and mobile communications. The relatively flexible mechanism to determine the number of beams, beamwidth and beam directions makes the proposed method very useful in the practical implementation of multi-beam antennas. The methodology is summarized with an example to demonstrate the feasibility.
