Abstract
Here, a simple cylindrical dielectric resonator is cut into two equal segments and the two segments are used to design a broadband hybrid monopole-dielectric resonator antenna. The impedance bandwidth of the proposed antenna is 100%, whereas that of a cylindrical dielectric ring resonator (with same radius and height) loaded monopole antenna is only 58%. Also, this new proposed antenna cause gain enhancement of 4 dB over that of a CDRR loaded monopole antenna. The width of the air gap between the two segments is varied, the monopole being placed at the center of the gap, and the corresponding results are studied. Another important aspect of this work is the excitation of HEM21ô like mode near 13 GHz in the composite (considering the two segments together) CDR.
