A design approach has been explored and successfully demonstrated to achieve an improved gain of a hybrid monopole maintaining its optimum achievable bandwidth. This challenge has been resolved based on the knowledge acquired in earlier investigations. A three-segment composite dielectric ring resonator (DRR) has been designed and fabricated. This, along with a vertical monopole, promises about 137% (5.4:1) matching bandwidth with consistent monopolelike radiation and 6–10-dBi gain over the entire band. Two sets of customized prototypes have been realized and experimentally validated to furnish the predicted characteristics in transmit and receive modes, both in frequency and time domain.
