“…Compact triband cylindrical DRA was represented by Sharma et al in 2.35 to 2.52 GHz, 3.35 to 3.65 GHz, and 5.1 to 5.42 GHz frequency ranges with ground plane area of 50 × 50 mm 2 . Moreover, a compact wideband 4‐port circularly polarized dielectric resonator antenna (CPDRA) is proposed for global navigation satellite system applications in the frequency band 1.150 to 1.620 GHz with a circular ground plane diameter of 90 mm . Conical DRA has been developed in 7.85 to 12.99 GHz range by Kishk et al which is aperture coupled and flipped staired with broadside radiation patterns …”

In this paper, compact circularly polarized triband (L5‐, L1‐, and S‐bands) staired rectangular dielectric resonator antenna (RDRA) is designed, analyzed, fabricated, and tested for navigation satellite applications. For triband RDRA, circular polarization is generated in L5‐band (1.164‐1.188 GHz) and L1‐band (1.565‐1.585 GHz) using dual section Wilkinson power divider (WPD) with wideband 90° phase shifter. For S‐band (2.48‐2.5 GHz), circular polarization is obtained by single section WPD with wideband 90° phase shifter. Ground plane footprint area of triband staired RDRA is miniaturized to 0.16λ0 × 0.16λ0 (40 mm × 40 mm) at lowest resonance frequency f1 of 1.176 GHz using high dielectric constant (εr = 38.67) dielectric resonator material and high dielectric constant (εr = 10.2) dielectric substrate (Rogers RO3210). Broadside radiation patterns of triband RDRA are generated for L5‐, L1‐, and S‐bands using TE111y, TE113y, and TE112y modes, respectively. Simulated and measured return loss at port‐1 of RDRA for L5‐, L1‐bands and port‐2 of RDRA for S‐band are better than 10 dB. Simulated and measured isolation between port‐1 and port‐2 of triband RDRA are found to be better than 13 dB for all bands. Peak right hand circular polarization gain is in the range of 0.6 to 4.5 dB over all bands for simulated and measured values. Simulated axial ratio is found to be better than 3 dB of triband RDRA. While measured values it is in the range of 0.91 to 7.02 dB.

“…Due to intrinsic characteristics such as small size, high radiation efficiency, small conductive losses and easy fabrication, dielectric resonator antennas (DRAs) have been studied for satellite communication applications. [1][2][3][4][5][6] DRAs are typically implemented in cylindrical or rectangular shapes. The cylindrical version is normally composed of a dielectric cylinder with height h, radius a and dielectric constant ε r glued on a ground plane (GND).…”

In this letter, a study of a feeding technique applicable to cylindrical dielectric resonator antennas is presented. The feeding technique analyzed is based on vias glued at the lateral wall of the cylindrical resonator. A series of parametric studies, in terms of the orientation, position and dimensions of the vias, has been carried out to assess the sensitivity to imperfections of the fabrication process on the antenna parameters. In order to validate the computational results, a prototype has been manufactured and measured with a spherical near-field test facility. The results in terms of S-parameters and radiation pattern are presented and good agreement between simulations and measurements has been obtained.
