Previously developed MATLAB code for designing planar (2D) metamaterial broadband ground planes is extended to design volumetric (3D) metamaterial structures. A 3D ground plane designed to operate as an artificial magnetic conductor (AMC) in the 225–450 MHz frequency range is presented. Its performance when used as the ground plane of the planar long slot array (PLSA) antenna and cylindrical long...
On many military tactical platforms, multiple wire-like narrowband antennas are employed, with each antenna covering a specific communication band. This approach enables the adversaries to distinguish the communication center and renders it a high priority target. The cylindrical long-slot antenna architecture can be used as an alternative ultra-wideband antenna to replace the multiple wire structures...
