Abstract :
As the future of wireless communication steers toward broadband and dual band applications the use of a basic monopole antenna is becoming less suitable. To meet the emerging broadband services a monopole antenna must improve its bandwidth characteristic and provide the same level of simplicity while maintaining its omnidirectional pattern. A proposed new design involves the use of a monopole antenna loaded with an annular ring dielectric resonator antenna operating in the TM/sub 01/spl delta// mode. In this arrangement both antennas produce a uniform horizontal coverage pattern.
