In this article, a single-layer circularly polarized reflectarray antenna (RA) with a linearly polarized feed is proposed for microwave power transmission. The unit cell of the reflectarray is composed of a rectangular patch surrounded by four groups of E-shaped structures, which feature a very low level of cross-polarization. Simulation results demonstrate that the phase of its reflection coefficient can be tuned continuously in a range of 500° by adjusting the lengths of the E-shaped structures. In response to a normally incident plane wave, the phase values of the reflection coefficient associated with two orthogonal linear polarization directions of the reflected wave can be tuned independently, which makes it possible to convert a linearly polarized incident wave to a circularly polarized beam. A reflectarray with 15 × 15 unit cells is fabricated and tested. The measurement results demonstrate a 3-dB axial ratio bandwidth of more than 2 GHz around the center frequency of 5.8 GHz. The measured gain value of the fabricated reflectarray is 25.4 dBi, corresponding to an aperture efficiency of 52.5%.

“…Although the design is compact and has good overall performance, but the drawback is that it is not circularly polarized. For C band satellite communication application, lower Ku band and overall UW dual band CP characteristics are achieved with the help of I-shaped monopole and two rectangular shaped orthogonally placed dielectric radiators, which is presented in [32]. The proposed design has a large size of 63 × 75 × 6.08 mm 3 .…”

This work focuses on a compact circularly polarized wideband rectangular dielectric resonator antenna (RDRA) for X-band wireless applications. The wideband response of the RDRA is initially generated by a coaxial probe, a compact RDR, an air gap in the DR and a slot of rectangular shape in the ground. The circular polarization is achieved via incorporation of a unique feeding mechanism. The edge feeding of the RDRA with a coaxial probe generates the orthogonal modes in RDRA that make the design polarized circularly. The axial ratio performance is improved by adding a copper strip on the top of the DR. To validate the simulated results, the prototype design is fabricated and measured results are noted. For −10 dB reference value, the prototype has 59.74% impedance bandwidth (8.45–14.09 GHz). For 3 dB reference value of the axial ratio, the prototype has 9.24% Circular Polarization (CP) performance (10.084–11.084 GHz). The design has 6.5 dBic peak gain and 95.5% peak efficiency. Results show that simulated results are in close agreement with the measured results.

“…As a result, for these dimensions, such a number of lens blocks demonstrates substantial inhomogeneity during the propagation of the wave. In Chakraborty et al 7 two single‐ended dielectric resonators are proposed. They are used to improve the characteristics of a planar antenna.…”

This article presents a study on the optimal aperture angle for the ultrawideband TEM horn with the dielectric filling. The electromagnetic simulation is performed at a wide range of frequencies and angles. Comparison of the considered parameters, such as radiation pattern and voltage standing wave ratio of the horn with and without dielectric filling allows defining optimal angles of the antenna.
