Computationally Efficient Semi-Analytical Model for Single Feed High Gain Antenna Structure

A semi-analytical model for a high gain antenna structure is presented. The model utilizes the uniform theory of diffraction to predict the gain performance of the antenna structure. The proposed model gives a physical insight about the structure radiation mechanism. The radiation mechanism can be analyzed by the use of edge diffracted fields. The use of edge diffracted fields allows the employment of array theory to further understand the structure behavior.
