In this study, we report two four‐element linear broadside arrays shaping the E θ and E ϕ 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, radiation pattern, gain, unloaded Q ‐factor, and impedance bandwidth of each array configuration are reported, and the experimental results are compared with the theoretical predictions. The gains of the two arrays were greater than the gain of the single element by factors of ∼5 and ∼3, respectively. Overall good agreement was obtained between theoretical and experimental results, with the numerical results being more accurate. © 1998 John Wiley & Sons, Inc.
