“…To solve these problems, a good choice is to design a miniaturized circularly polarized (CP) antenna with a wide beamwidth. 4 Metamaterials as a novel artificial electromagnetic media with unusual and useful properties are widely used in various antenna design, [5][6][7][8][9] especially for miniaturized metamaterialbased antennas. [8][9][10] Several small metamaterial-based/inspired antennas were proposed in References 8 and 9 but they suffer from narrow bandwidth and large loss.…”

This paper describes a metamaterial-based miniaturized circularly polarized (CP) antenna with high radiation efficiency and wide beam-width or coverage for 5G indoor application. A novel meta-resonator is first proposed, which is investigated by transmission line and equivalent circuit models. By exploring a split-ring resonator-like metaresonator structure, a high-Q LC resonator tank is formed. Substantial size reduction and a wide beam-width are achieved. Owing to a uniform field on these multiple capacitive gaps incorporated on this meta-resonator surface, enhanced aperture efficiency and gain are obtained. It is partly inspired by the classical metasurface-based antenna. For validation, a miniaturized CP antenna with a size of 0.29 λ 0 × 0.29 λ 0 × 0.04 λ 0 (where, λ 0 is the free-space wavelength at 3.55 GHz) is fabricated and measured. The fabricated antenna achieves a good bandwidth of 3.30-3.80 GHz that well covers 5G-N78 band, a peak radiation gain of 5.4 dBic, a high radiation efficiency of 90% and a wide half-power beam-width of 91 . It exhibits the merits of compact size, good bandwidth and beam-width, high efficiency, and low-cost, demonstrating good potential in miniaturized 5G indoor systems demanding wide-beam coverage.

“…Recently, metamaterial and metasurface‐based structures have received much interest due to their applications for improving the antenna performances 1‐16 . Planar Fabry‐Perot resonator antennas have widely been used for gain enhancement using a single or multilayers of partially reflective surface (PRS) 1‐8 . In addition, combining PRS and holographic (HM) metasurfaces have also been used for RCS reduction and gain enhancement 6 .…”

In this paper, a Fabry-Perot cavity antenna with an improved gain using AMC-reflector and FSS superstrate approaches is proposed. The antenna is designed at 5.8 GHz for IoT applications, it constitutes of I-shaped slot antenna, an artificial magnetic conductor (AMC) reflector and a superstrate of frequency selective surfaces (FSS). Three antenna configurations are provided to improve the gain and reduce the side lobe levels (SLL). First, an I-shaped slot antenna operates at 5.8 GHz, is proposed. The second configuration provide an AMC reflector layer, placed under the antenna, to degrade SLL in the desired band. Finally, three FSS superstrate layers located above the I-shaped slot antenna in order to maximize the level of the main lobe. An experimental prototype is fabricated, tested and presented to demonstrate the proposed antenna design. Simulated and experimental results, in terms of reflection coefficient, radiation pattern and gain, are presented and discussed to assess the proposed antenna design.

“…Although the offset feed can eliminate the effect of feed blockage, the reflectarray antenna still may not be suitable for certain applications because of high profile. Because the feed and array are integrated into the same plane, the profile of the FPRA is low 4‐10 …”

This article presents a novel dual‐band and dual‐polarization Fabry‐Pérot resonator antenna (FPRA). The proposed FPRA consists of a partially reflective surface (PRS), an electromagnetic bandgap (EBG) structure, and a dual‐band and dual‐polarization planar patch antenna. The novel PRS with a large positive reflection phase gradient (PRPG) is etched on a single‐layer superstrate. The EBG structure is adopted as the reflection plane to reduce the profile of FPRA. A rectangular microstrip patch antenna integrated into the center of the EBG structure is used as a dual‐band and dual‐polarization feed for FPRA. A dual‐band and dual‐polarization FPRA is proposed, fabricated and measured. The measurement results demonstrate that the proposed FPRA has peak gains of 14.3 dBi with the horizontal polarization (H‐pol) at 12.4 GHz and 16.8 dBi with vertical polarization (V‐pol) at 14.1 GHz. Moreover, the measured 3‐dB gain bandwidths in the lower and higher bands are 7.3% and 3.6%, respectively, which cover receiving (Rx) and transmitting (Tx) bands of satellite communication in the Ku band.
