“…[1] The PUMA antenna proposed by Vouvakis in 2010 is a novel form of tightly coupled antenna. [2] Compared with the TCDA antenna originally proposed by Professor Munk's team, this antenna does not apply any external baluns, and has a simple feed structure. It suppresses the common-mode phenomena caused by the unbalanced feed out of the pass band by connecting a short-circuit probe to the dipole arm.…”

In this paper, a dual-polarized planar ultra-wideband modular antenna (PUMA) with wide-scanning angle matching layers is proposed. The multiple dielectric layers and frequency selective surfaces (FSS) are loaded on the dipoles. Each frequency selective surface is etched on the dielectric plate as one wide-angle -matching layer. By applying three wide-angle-matching layers, the wide-scanning angle performance is guaranteed. As for the ultra-wideband performance, a metal cylinder is added to the lower space between adjacent dipoles, and the upper end of the cylinder has a certain distance from the dipole. This forms a “ridge” structure which shift problematic common-mode resonances caused by circulating current out of band. A dual-polarized 256-port array (16×16) is set and simulated. The simulation result indicates that the proposed antenna operating over 4.79GHz -20.15GHz (4.20:1) achieves VSWR<3 while scanning to 60° in E-plane and D-plane, and to 45° in H-plane respectively.
