Abstract :
A simple and broadband, microstrip-fed high aspect ratio dielectric resonator antenna is presented and fabricated. The broadband characteristic is achieved by merging the resonances of two appropriate modes of the antenna. The measured antenna bandwidth can exceed 16% with dielectric constant of 25. The approach provides stable radiation patterns as well as low cross-polarisation levels over the entire bandwidth.
