β¦ Synopsis
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 single DRA. Howeuer, the impedance bandwidth has been redued by a factor of 2.3 with respect to the bandwidth of a single DRA. Good agreement exists between the theoretical and experimental results.

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
A circularly polarized dielectric resonator DR antenna array composed of two linearly polarized cylindrical DR antennas with ¨ery high permitti¨ity is demonstrated. The cylindrical DR antennas are excited through an annular slot cut in the ground plane of the microstrip feed line. The present design
The stacked structure of an aperture-coupled cylindrical ( ) dielectric resonator DR antenna is studied experimentally. The effects of the offset and the air gap between the dri¨en and parasitic DR elements are in¨estigated. It is found that the bandwidth of the stacked structure can increase from t
