An Interactive Application for the Design of a Pyramidal Horn Antenna Using Rectangular Waveguide Technology

This article presents an interactive application for the design of a pyramidal horn antenna using rectangular waveguide technology. The application is targeted specifically at students to understand the design process of a pyramidal horn antenna and visualize the 2-dimensional and 3-dimensional radiation patterns. Commercial proprietary software which enables understanding are often expensive and are not easily accessible to students worldwide. The interactive application presented in this paper is available for free of cost and is easy to use without requiring sophisticated computational resources. The results of the application are compared with a commercial electro-magnetic simulator and a good correlation between the results from the application and simulator is seen. The statistical study shows an improvement of 58.8% in the learning scores after using the application among the postgraduate students. The mean of before scores and after scores is 4.66 and 7.4, respectively.
