Monopole Slot Coupling-FED Dielectric Resonator Antenna for Mobile Terminals

This paper presents a novel dielectric resonator antenna (DRA) for multiband mobile terminal communication applications. A variation of circular sector dielectric resonator antenna partially coated with metal on its surface is used as the main radiating element. The DRA is fed by a monopole slot-coupled 50-Ω microstrip feed line, which can also provide another radiation mode. By thorough design, the antenna achieves the desired 470-960 MHz band for DVB-H/GSM850/900 operation and 1710-1990 MHz band for DCS/PCS operation. The dimensions of the antenna presented are /17 x /9 x /35 at 470 MHz with appropriate dielectric permittivity .
