Bandwidth enhancement of rectangular-dielectric resonator antenna using combined circular and rectangular slots technique

摘要

This work is about improving the properties of antenna with resonant structure modeling, using dielectric resonator antenna (DRA). Simulation is carried out with the use of commercial software HFSS. The proposed circular slot technique applied here as an excitation techniques to improve the characteristics of the antenna and particularly to widen the bandwidth between 1.74 and 2.92 GHz.
