Elliptic slot antenna for broadband wireless communications

Abstract

This paper presents the design of a broadband antenna suitable for wireless communications operating over the frequency range of 3.1–10.6GHz. Parametric studies on the effect of stub and elliptic slot have been carried out to arrive at optimum dimensions to achieve enhanced bandwidth of the proposed antenna. An experimental antenna has been designed and tested to validate the proposed design. Measured return loss characteristics have been compared against the simulation results. Simulated radiation patterns at 3.1GHz, 6.85GHz and 10.6GHz have also been presented in this paper.
