Abstract :
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 of the antenna are analysis using CST Microwave Studio™ in terms of reflection coefficient, gain and impedance bandwidth and are compared with the computational value. It is observed that the new proposed configuration reduces the DRA volume by 25% and at the same time enhances the gain up to 7.2dB and bandwidth significantly up to 31% with slot cut in DR. The proposed antenna is considered as a good candidate for wideband wireless communication systems.
