“…By varying the length to width ratio and with suitable excitation, two degenerate modes with 90 • phase differences can be excited in the DRA, resulting in circular polarization [7,8]. If a rectangular DRA excited by a narrow rectangular slot positioning 45 • with respect to the sides produces circular polarization.…”

Abstract-This paper presents a design of circularly polarized dielectric resonator antenna (DRA) array. The dielectric resonators (DRs) were excited by rectangular aperture coupling slots feed with a linear microstrip. The slot positions were determined based on the characteristic of standing wave ratio over a short ended microstrip to deliver the maximum amount of coupling power to the DRs, in order to improve the array gain Each DR element was rotated 45 • with respect to the sides of the exciting slot to generate circular polarization pattern. The DRA array was modeled and simulated as a parallel RLC input impedance component using Agilent (ADS) software, since that will ensure the resonant frequency of the antenna as primary design step before simulating in (CST) software and doing the measurements. The results of the return loss, gain radiation and pattern axial ratio are shown. The gain of the proposed array in X band was about 8.5 dBi, while the 3 dB axial ratio bandwidth started from 8.14 to 8.24 GHz. The impedance bandwidths started from 8.14 GHz to 8.26 GHz. The proposed DRA exhibited an enhancement of the gain in comparison to a single pellet DRA. The size of the whole antenna structure is about 40 mm × 50 mm and can potentially be used in wireless systems.

“…For instance, a CP rectangular DRA using a single-slot feed has been reported [4], where an axial ratio (AR) bandwidth of 1.8% has been achieved. An elliptical DRA with a circular polarization bandwidth of 3.5% has been investigated using a single-probe feeding [5].…”

“…With a single feed, orthogonal modes can be excited in the DRA by applying parasitic patches [10] or by exciting the DRA asymmetrically [11]. These methods, however, are generally very narrow-band with respect to the axial ratio, and therefore practical designs often make use of multiple feeds excited in phase quadrature, e.g., [12].…”
