This paper discusses the on-site flexibility afforded in modifying the radiation parameters of a water Dielectric Resonator Antenna (DRA) by varying the height of its water column. These radiation parameters are Main Lobe Magnitude (MLM), Main Lobe Direction (MLD), Angular Width (AW), and Side Lobe Level (SLL), observed in the frequency range of 0.5 GHz to 8 GHz. Upon varying the height of the water column of the antenna under test (AUT) with FR-4 (Lossy) as the dielectric layer material, we find that different heights of the water column provide different flexibilities along the antenna parameters of MLM, MLD, AW, and SLL, and hence makes such an antenna adaptably suited for C-Band applications.

Keywords- DRA, VSWR, bandwidth, gain, main lobe magnitude (MLM), main lobe direction (MLD), angular width (AW), side lobe level (SLL), Q-factor
