Design of a Dualband Mono-DRA for Marineship Applications

The combination of monople and circular dielectric resonating antenna (DRA) was first proposed by the researchers from Canada for wideband applications [1]. In 2006, D. Guha and Y. M. M. Antar investigated the different shapes of the antenna topology to obtain a wide working band [2]. Then, D. Guha and B. Gupta concluded the design rules of hemispherical and conical resonator on influencing the antenna performance [3]. At the same time, some researchers also explored the methods of the stacked layers and hybrid structures for an improved bandwidth design [4] –[6]. In general, the DRA loaded monople antenna offers a great potential for the wideband applications with the advantages of simple structures and easy for installations.
