Abstract

This paper provides a comparative analysis of cylindrical dielectric resonator antenna with simple micro-strip feed to that of a modified micro-strip feed. The fundamental radiator is having a radius of 5.96 mm and height of 9.82 mm with relative permittivity εr of 10. It is placed over a substrate having dimension 40×40×0.785 mm3 with εr equal to 2.5. The substrate is embedded with an infinite ground plane to reduce the physical height of the antenna according to image theory. Two types of micro-strip feeding mechanisms are being experimented. The simplified micro-strip feed radiator resonates at 5.7 GHz with impedance bandwidth of 14.03%. The modified micro-strip feed with an added stub resonates at 10.65 GHz & 13.5 GHz with impedance bandwidth of 21.596% & 13.33% respectively. Matching profile, directive gain and efficiency can be enhanced by almost 10% by modifying simple micro-strip feed to micro-strip feed with stub structure of proposed antenna.
