Abstract— This paper describes a pyramidal horn antenna design which it works in a microwave domain. His

operating frequency is 4.7 GHz. The parameters of the antenna were measured through its numerical modeling using HFSS (High Frequency Structure Simulator) electromagnetic simulation software. HFSS has the capability to calculate and

plot a 3D image depicting the real beam of the gain. The obtained results show that an antenna gain of 12.90 dB was obtained at the frequency of 4.7 GHz, which means that the antenna is properly adapted to the transmission systems.

This antenna will be used for non destructive testing (NDT) application, such as detection of cracks in different materials, materials characterization.

Keywords— pyramidal horn antenna, finite element method, HFSS, Radiation pattern, gain, non destructive testing (NDT).
