Abstract :
In this paper, electrical models of single element cylindrical dielectric resonator antenna (CDRA) and two element CDRA array made of Calcium Copper Titanium Oxide (CCTO) material are presented. The 50 Δ microstrip transmission line is used to excite the CDRAs through coupling slots etched on the ground plane. The electric models of single element CDRA and two element CDRA array are designed by using Advanced Design System (ADS). The electrical circuits are used to validate the CST design feasibility. The validity of RLC model is verified by comparing the return loss of the ADS model against those obtained through computer simulation technology (CST) and fabricated prototype. The results obtained through simulated (CST and ADS) designs and fabricated prototype of single element CDRA (0.20 GHz and 0.23 GHz) and two elements CDRA array (0.375 GHz and 0.510 GHz) are in good agreement.
