Abstract :
Experimental investigations carried out at 20 GHz on various linear arrays of dielectric resonator antennas with different feeding mechanisms are reported. Linear arrays with microstrip feed, dielectric image guide feed, and slot aperture feed were fabricated and their performance was evaluated. A discussion of the practicality of each array is included.
