Abstract

In this work, characteristics of an arc-monopole loaded with a DRA is analyzed. It is observed that the arc-monopole can be used to effectively couple to multiple DRA modes and generate dual/triple/wideband topologies. The structure is easy to fabricate with no additional substrate or matching slot/vias required to excite the multiple DRA modes. In addition, both broadside and monopole like patterns are obtained for the dual/triple band configurations which are suitable for communication with satellite or airborne targets and for surface-to-surface communication. The enhanced radiation in the source plane for the monopole like pattern can be effectively used to communicate with preferred targets or enhance the range in the direction of interest. In addition, the arc-monopole can be suitably located to couple the source mode to the DRA modes to generate broadband behavior.
