A new pawn-shaped dielectric ring resonator (DRR) fed by a simple quarter-wave monopole has been investigated as a new variant of the hybrid monopole-dielectric resonator antenna (DRA). The new geometry, conceived intuitively, significantly improves the impedance bandwidth compared to all earlier versions reported in open literature. S11 < -10 dB occurring over 5.523 GHz has been experimentally...
