Design of Elliptical Shaped Multiband Antenna for Application in Wireless Communication

in this paper, a simple stretched ellipse patch antenna for multiband operation is introduced. An ellipse - shaped slot has been etched at the center of the patch for bandwidth enhancement. The obtained bandwidth has a range of (3.2 - 11.5) GHz with multi resonance frequencies which are useful for various wireless applications. The dimensions of the proposed antenna are (103.4×96.56) mm

using a substrate having a relative permittivity of 4.2 and a thickness of 1.5 mm. The model of the proposed antenna has been designed and simulated using the CST Microwave Studio.
