β¦ Synopsis
Two four-element linear aperture-coupled cylindrical dielectric resonator antenna arrays ha¨e been theoretically modeled and experimentally implemented. The arrays produced broadside radiation shaping the E-and H-plane, respecti¨ely. The resonant frequency, return loss, radiation pattern, gain, unloaded Q-factor, and impedance bandwidth of the arrays ha¨e been measured. O¨erall, good agreement was obtained between theory and experiment.

In this study, we report two four-element linear broadside arrays shaping the E and E field components. The radiating elements are probe-fed cylindrical dielectric resonator antennas. The arrays are analytically formulated, numerically simulated, and experimentally tested. The resonant frequency, ra
## The radiation from two different broadside dielectric resonator antenna arrays, shaping the E, and E+ field components, has been theoretically modeled and experimentally verified. The gains of the two arrays hace been incieased by factors of 2.6 and 1.6, respectively, compared with the gain of a
