Two-element endfire dielectric resonator antenna array

The radiation from a two-element endfire dielectric resonator antenna array has been experimentally investigated and compared with theoretical formulations. The measured gain of the array is 4.6, which is 35% higher than the gain of a single element DRA. The measured impedance bandwidth is 11.4%, which is 0.7% lower than the bandwidth of the single element DRA. Good agreement has been observed between the predicted and measured results.
