In this article, a narrow and a wide band high gain antenna with improved front to back ratio using highly reflecting surface are proposed. A highly reflecting compact ultrathin metasurface (MS) of thickness 0.0134 λ with >90% reflection band of 1.42 GHz from 4.55 to 5.97 GHz is designed. The open air field Fabry-Perot cavity resonator antenna is designed by placing this MS over a microstrip patch antenna radiator first and next on standard wide band C-band wave guide port radiator at an optimum height to get narrow and wide enhanced gain band width, respectively. The proposed antennas are fabricated and measured experimentally. A low profile narrow band FPC antenna with measured broad side gain enhancement of 8.54 dB having maximum measured gain of 16.5 dBi at 5.3 GHz is designed first. Next, a wide band FPC antenna having broad side measured enhanced gain band width of >1 GHz from 4.75 GHz to about 6.00 GHz with maximum gain enhancement of 8.32 dB with maximum measured gain of 17.85 dBi at 5.30 GHz is observed. A wide improved front to back ratio (FBR) band of 1 GHz with maximum FBR of 39.5 dB at 5.30 GHz is presented. This antenna can be used for 5G long range services.

This paper proposes a novel triple-layer partially reflecting surface (PRS) for designing a highly directive antenna. The proposed PRS design has 54% improvement in impedance bandwidth with existing design. The design has multiple cavities, optimized for improved gain and bandwidth performance. The PRS arrays are printed on the dielectric substrate, placed above the ground plane at a height of approximately half wavelength. The reference square microstrip patch antenna operating at a frequency of 5.8 GHz with a gain of 3.77 dBi is enhanced to 13.54 dBi. The measured S11 of the fabricated prototype is −22.12 dB with a VSWR of 1.17 : 1. Measured 3 dB gain bandwidth of the antenna is 390 MHz which is an improvement of 50% compared with the reference antenna. This highly directive antenna is suitable for WiMAX wireless application.

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.
