A transmission line model for co-designed slot-coupled dielectric resonator antennas

• Co-design of monolithically-integrated millimetre-wave front-ends and antennas is alleviated by accurate device models. In this paper, a novel transmission line model for slotcoupled dielectric resonator antennas is proposed and verified. It describes distributed interaction between the coupling-structure and the radiating dielectric body of the antenna. This model thereby provides a simplistic and intuitive description of the main radiation mechanism. It fits with excellently to numerical full-wave simulation results, both in terms of input characteristics and radiation efficiency. Furthermore, the radiated signal fidelity predicted by the model is found in line with experimental results from a co-designed millimetre-wave wavelet transmitter. This antenna model promise further development into a generic scalable model that will reduce the need for iterative simulations.
