Summary:
This paper presents the Uniform Theory of Diffraction ( UTD) analysis of an inclined rectangular aperture antenna mounted on an open-ended cavity excited by a probe. This work is taken into account the uniform theoiy of diffraction to improve the results from the previous works by using the dyadic Green function approach. The geometry of the problem is made up of the rectangular aperture mounted on inclined open-ended cavity. This structure is fed by a probe inside the cavity. The study starts with the consideration of the geometry of the diffraction such as the incident field, the shadow boundaries and the relative parameters. Subsequently, the diffracted fields and the total fields that radiated from the antenna are evaluated to precise the radiation pattern from the aperture antenna. The results in this work are significant to further design the aperture antenna from the open-ended cavity fed by probe in the microwave and the wireless communication applications.
