Abstract :
A new class of Planar Ultrawideband Modular Antenna (PUMA) arrays, the PUMAv3, is introduced. PUMAv3 is scalable to mm-wave frequencies (≈50 GHz) and improves bandwidth by 50% without the use of a matching network or external baluns. The enabling technical innovations include a new feeding mechanism that relies on capacitively loaded shorting vias and an alteration on the superstrate loading scheme. Infinite array full-wave simulations of a dual-polarized PUMAv3 suggest 10.6-47.6 GHz (4.5:1) operation with good VSWR levels out to θ = 45°, high port isolation and low cross-polarization.
