Design of Ultra-Wide Band Monopole and Multi Annular Ring Dielectric Resonator Antennas for Next Generation Wireless Communication Systems
並列摘要
In antenna design, based on application requirements various criteria such as bandwidth, directivity, radiation efficiency, construction, cost, and fabrication difficulty are used for product evaluation. Among these criteria, design of an antenna with ultra-wide bandwidth has increasingly been demanded for next generation wireless communication systems. Purpose of this research is to developing such a broad band antenna by using a hybrid structure consists of a monopole antenna (with variations) and multi-annular dielectric resonator antennas. From simulation via Ansys HFSS^(TM), one of our designs reaches a high bandwidth ratio beyond 5:1. Further, one variation of the design can obtain an even broader bandwidth ratio beyond 15:1.
