Abstract :
Here, we design and analyze several dual polarized dielectric resonator antennas (DRA) excitation techniques and compare their advantages and disadvantages. A simple cylindrical disk DRA is used. It is designed to resonate around 10 GHz. The feeding mechanisms include probe excitation, aperture couple excitation and co-planar waveguide (CPW) feed. In addition, we also discuss combinations of different feeding mechanisms, such as probe/aperture or aperture/CPW. The comparisons are based on resonant frequency, common matching bandwidth (S11 < -10 dB), isolation and radiation pattern symmetry
