This paper presents the utilization of a wideband horn antenna to work in the nondestructive testing system (NDT) operation frequencies. Which used as detection of cracks in different materials, and materials properties. The proposed structure based on a horn antenna works at frequencies of 4.5GHz until 6GHz. The proposed structure designed using microwave equations and simulated using CST (computer simulator technology) using finite element technique. Two samples, one without defect and the other with a defect 10%, 20% and 30%, will investigate for comparing the microwave characteristics of the antenna. The results show that a horn antenna can used to detect the material properties by observing the reflection coefficients and electrical field distribution inside the material.
