This letter presents the mutual coupling reduction in Fabry-Pérot (FP) cavity antenna array. Partially reflecting surface (PRS) and analogous artificial magnetic conductor reflectarray in the cavity participate in phase and magnitude modulation with spatial decoupling solution. With the proper design for the cells of PRS and reflectarray, along with the distance between them, scattered and surface waves are analyzed independently to achieve the trade-off between mutual coupling reduction and high directivity. With decoupling optimization, S 21 decreases from −20 to −30 dB, and the gain of the decoupling FP cavity antenna array fed by single source drops acceptably from 14.3 to 13.6 dBi simultaneously. The low E-plane coupling coefficient and envelope correlation coefficient are achieved. Besides, the height of the decoupling FP cavity antenna array is lower than 6.3 mm owing to the participation of reflectarray. That the measured results are in good agreements with simulated results verifies the decoupling FP cavity antenna array performances.

“…In order to achieve the desired Φ PRS response for the broadband operation, a variety of different PRS structures have been proposed for the FPA. Examples include multi‐layer frequency selective surfaces, metasurface with tapered near‐zero effective index, multiple dielectric superstrates, thick dielectric superstrate . Most of the previous FPAs, however, essentially focused the gain‐bandwidth enhancement; their improvements in terms of impedance matching bandwidths and axial ratio (AR) characteristics have thus far been neglected.…”

“…Most of the previous FPAs, however, essentially focused the gain‐bandwidth enhancement; their improvements in terms of impedance matching bandwidths and axial ratio (AR) characteristics have thus far been neglected. For demonstrating the broad gain‐bandwidth, the FPAs popularly utilized wideband feed antennas, such as slot waveguide antennas, enlarged‐dipole, crossed bowtie‐dipoles, dual‐feed stacked patch antenna, and Archimedean spiral antenna, and therefore, their operational bandwidths are normally narrower than those of the feeding elements. Narrow‐band antenna types (eg, dipole or conventional patch), which typically yielded only one‐resonance, were also employed as the feed element of the broadband FPAs .…”

In this article, we investigate bandwidth‐enhancement of a circularly‐polarized (CP) Fabry‐Perot antenna (FPA) using single‐layer partially reflective surface (PRS). The FPA is composed of a single‐feed truncated‐corner square patch antenna, which is covered by the PRS formed by a square aperture array. We revealed that the finite‐sized PRS produces extra resonances and CP radiations for the antenna system, which broadened the impedance matching and axial ratio (AR) bandwidths significantly. For verification, a broadband CP FPA prototype operating near 5.8 GHz was realized and tested. The fabricated antenna with overall size of 125 mm × 125 mm × 23.5 mm achieves a |S11| < −10 dB bandwidth of 31.7% (5.23‐7.2 GHz), an AR < 3‐dB bandwidth of 13.7% (5.45‐6.25 GHz), the peak gain of 13.3 dBic, a 3‐dB gain bandwidth of 22.38% (5.0‐6.26 GHz), and a radiation efficiency of >91%.

A microstrip patch antenna working at 2.4 GHz at ISM band is presented in this work by employing an altered anchor‐shaped dual‐layer frequency‐selective surface (DLFSS) on a microstrip substrate. Both the traditional method and the proposed one are shown in order to show the advantage of employing this DLFSS structure. In the new technique, simulations and design optimizations of the antennas and FSS structure are undertaken on a low‐cost FR4 substrate with εr = 4.4, h = 1.58 mm and tanδ = 0.0035 in the given 3D CST MSW setting. The traditional FSS technique of the same configuration is also used in the same setting and the outcome of the antenna performance with and without DLFSS is replicated and compared. The results show that the measurements given by the suggested new model are in synchronization with the theoretical results and prove that they have greater gain and beam width at 2.4 GHz bandwidth; they also show improved return loss.
