“…There are many studies in the literature concentrated on reconfigurable RCA structures. These studies investigate frequency [108][109][110][111][112], beamwidth [113][114][115], and polarization [116][117][118][119][120][121][122][123][124][125][126][127], and pattern reconfigurability [128][129][130][131][132][133][134][135][136][137][138][139].…”

“…Polarization reconfigurability can be achieved by using either a reconfigurable main radiating element [116][117][118][119][120][121][122] or a dependent polarization PRS [123][124][125][126][127]. In Reference [140], a four-polarizationreconfigurable aperture-coupled patch antenna is designed as the main radiator of a RCA structure, which works with two different linear polarizations.…”

Resonant cavity antennas (RCAs) are suitable candidates to achieve high-directivity with a low-cost and easy fabrication process. The stable functionality of the RCAs over different frequency bands, as well as, their pattern reconfigurability make them an attractive antenna structure for the next generation wireless communication systems, i.e., fifth generation (5G). The variety of designs and analytical techniques regarding the main radiator and partially reflective surface (PRS) configurations allow dramatic progress and advances in the area of RCAs. Adding different functionalities in a single structure by using additional layers is another appealing feature of the RCA structures, which has opened the various fields of studies toward 5G applications. This paper reviews the recent advances on the RCAs along with the analytical methods, and various capabilities that make them suitable to be used in 5G communication systems. To discuss different capabilities of RCA structures, some applicable fields of studies are followed in different sections of this paper. To indicate different techniques in achieving various capabilities, some recent state-of-the-art designs are demonstrated and investigated. Since wideband high-gain antennas with different functionalities are highly required for the next generation of wireless communication, the main focus of this paper is to discuss primarily the antenna gain and bandwidth. Finally, a brief conclusion is drawn to have a quick overview of the content of this paper.

“…In this LTC-PC, the bandwidth has reached 2 octaves in the range of 0.4-2.4 THz [14]. An LTC-PC aperture-coupled antenna with an ultrathin singlelayer metasurface has been proposed in [15] to achieve boresight radiation gain around 10 dBic over 9.5 GHz to 11.5 GHz. The axial ratio bandwidth of the proposed antenna is also 19.23%.…”

Terahertz linear to circular polarization converter based on reflective metasurface

Metasurfaces are two-dimensional artificial structures which have extraordinary electromagnetic properties. They have been used in myriad of devices such as nano-antennas, cloaking coatings, imaging devices, flat lenses, and polarization converters over a wide range of frequency. Due to high dependency of many devices on incident wave polarization, manipulating the polarization of electromagnetic waves would be useful, especially in the THz regime. In this study, we propose a linear to circular polarization converter (LTC-PC) based on a THz reflective metasurface. For a TE linear polarization incident wave, this structure has two distinct bands; the first one lays in a wideband frequency range of 0.5-1.41 THz, in which the reflected wave would be a left-handed circular polarization (LHCP) with minimum efficiency of 89% and maximum efficiency of more than 95% in 80% of the bandwidth. The second band lays in the narrowband frequency range of 1.45-1.55 THz, resulting a right-handed circular polarization (RHCP) wave with a minimum efficiency of 82%. The proposed polarization converter can be used in optical communication and electronic devices.

“…In recent years, metasurface antennas have been applied to CP antenna design by more and more scholars to improve the impedance bandwidth, axial ratio bandwidth (ARBW), and the gain of the antenna [6,7]. In [8], a metasurface unit for polarization conversion was proposed, where the unit consisted of a hexagonal ring enclosed within a rectangular ring and printed on both sides of the dielectric substrate. Although the high gain was achieved, the impedance bandwidth and ARBW were both narrow.…”

In this paper, a low-profile, broadband metasurface antenna for polarization conversion is proposed based on characteristic mode analysis (CMA). A new type of metasurface unit with a partially chamfered symmetrical triangular structure is designed. The inherent physical characteristics of the antenna are analyzed based on CMA, and the expected characteristic modes are selected for excitation at a suitable position. Slot-coupled feeding via microstrip line realizes the performance of wide impedance bandwidth and axial ratio bandwidth (ARBW). The measured -10 dB impedance bandwidth of 36.3% (4.38–6.32 GHz) and the 3 dB ARBW of 20.1% (5.41–6.62 GHz) are achieved. The left-hand circular polarization (LHCP) is realized, and the measured highest gain in the working frequency band is 6.05 dBic. The overall size of the designed and fabricated metasurface antenna is 0.58 λ0 × 0.58 λ0 × 0.07 λ0at 5 GHz. The proposed metasurface antenna can be well used in C-band satellite communications due to its low profile, broadband, and circular polarization.
