Abstract

In this paper, the experimental study on cylindrical dielectric resonator antenna (CDRA) with an aperture coupled dielectric image line (DIL) is presented using a CCTO material. The CDRA is fed by a 50Ω dielectric image line at a frequency around 2.45 GHz. High permittivity (ε_r = 55) DIL samples with different heights are employed. The CST microwave studio is used to analyze the different results in term of return loss, bandwidth and radiation pattern. The DIL feeding technique has shown a better directivity for CDRA as compared to microstrip line coupling.
