A Convex Hexagonal Dielectric Resonator Antenna (DRA) with parasitic plate is proposed and investigated successfully. Parasitic plate mounted on the dielectric resonator increases the bandwidth from 35.2% to 56.01% without affecting the size of antenna. The antenna is coupled with 50Ω microstrip transmission line. The result shows that the DRA with parasitic plate produces a wide band, which is 56...
An approach to improve the bandwidth and gain of Dielectric Resonator Antenna (DRA) using air gap slots are presented. Air gap slots can be used to widen the DRA bandwidth or to tune the DRA frequency. This new structure offers a good impedance bandwidth and wide-band DRA. In addition, the projected antenna has a quite higher and more stable gain than that of reference antenna. The characteristics...
