Antenna Pattern Generation

The utilization of antenna arrays is a common practice in achieving elevated gain and directivity. The manipulation of amplitude coefficients, phase coefficients, and inter-element spacing allows for the regulation of antenna pattern. Various methodologies are employed in the production of contoured beams. This paper presents the necessary amplitude coefficients for a linear array antenna to generate Sector Beam and Stair Step patterns. The method of stationary phase is utilzed for conducting analysis. The process of synthesis is executed within the MATLAB software environment. The findings obtained from the computation of the Sector beam and Stair Step pattern are presented.
