Microwave antennas using microstrip line with orthogonally placed dielectric resonator

Microwave dielectric resonator antennas using orthogonal orientation of the resonator relative to a microstrip line have been studied. The mathematical expressions characterizing interrelations between key parameters of a single-element antenna were obtained. The analytical relation for antenna return loss versus stub length and coupling coefficients of dielectric resonator with the feeding line and open space is derived. The assessment of the potential possibility and conditions of perfect antenna matching with feeding line is carried out. The numerical analysis of different antenna parameters proving the obtained analytical expressions is performed. A 4-element antenna array using the introduced excitation scheme is proposed.
