Abstract
A linear array of rectangular dielectric resonator antenna (DRA) elements was designed using a dielectric image guide (DIG) feed. The amplitude control of each DRA clement was achieved by varying the distance between the element and the feed line. A 14-element Dolph-Chebyshev distribution was simulated at 30GHz. The simulation results showed a peak gain of 15.3dBi, and cross-polarization levels better than -15dB.
