Design Curves for Estimating the Resonant Frequency and Q-factor for Rectangular Dielectric Resonator Antennas

Analysis and design curves for rectangular dielectric resonator antennas (DRA) are presented. The curves, based on the dielectric waveguide model, allow a designer to quickly predict the resonant frequency and Q-factor of a rectangular DRA without the ...
Dielectric resonator antennas (DRA) are a relatively recent addition to antenna technology and have been the focus of increasing research activity over the last two decades. A DRA is a resonant antenna fabricated from low loss microwave dielectric material whose resonant frequency is predominantly a function of size, shape...
