Abstract :
Probe-fed dielectric resonator antenna (DRA) arrays are studied for operation in a waveguide environment with application to spatial power combining systems. The method of analysis is based on the finite-difference time-domain (FDTD) approach. A traditional Yee cell is used to discretize a rectangular waveguide and the DRA array elements are fed by wire probes through coaxial lines, which are modeled by a thin wire approximation.
