Abstract

This paper presents the diffraction on a rectangular aperture antenna mounted on an open-ended cavity excited by a probe. This research is taken into account the Uniform Theory of Diffraction (UTD) 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 the open-ended cavity with the probe fed 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 related parameters. Subsequently, the diffracted fields and the total field 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 application. © 2006 IEEE.
