Simplified design of 6∶1 PUMA arrays

Advances in Planar Ultra-wideband Modular Antenna (PUMA) array architecture which have culminated into a 6:1 bandwidth design without the use of an external backplane matching network are presented. This paper will examine the additional bandwidth-enhancing operational principles of the proposed dual-polarized 6:1 PUMA array. A design and its respective full-wave simulations will then be presented, with results yielding a 6:1 bandwidth with VSWR <; 2 at broadside, VSWR <; 2.6 scanning out to θ = 45°, and a diagonal plane cross-polarization greater than 15 dB at θ = 45° for the majority of the band.
