Abstract

A Concentric 3-Layer half-split cylindrical dielectric resonator antenna (CDRA) for wideband application has been designed and developed. The effect of antenna parameters such as layer arrangement, geometrical parameters and probe length are investigated. The fabrication is performed with commercially available microwave laminates. The proposed antenna has measured impedance bandwidth of 84.72% (S₁₁ ≤ -10 dB) at 5.50 GHz, which is from 4.51 GHz - 9.17 GHz. The proposed antenna has good radiation characteristics, with an average gain of 9.15 dB in the operating band, which is very suitable for wideband wireless system applications.
