“…Recently, metasurfaces have been employed in several novel antenna designs for bandwidth and gain enhancement [12], [13], [14], [15], [16], [17], [18], [19], [20], [21], [22], [23]. These enhancements are directly related to improving the design's physical properties, i.e., reducing surface waves and back radiations.…”

Weight-size optimization is the main challenge of high-power antenna design. This letter presents a low-profile, metasurface-based wideband antenna. The proposed antenna comprises an N-type-to-waveguide transition to excite the metasurfaces and handle high-power excitations. A metasurface array of 4×4-unit cells is integrated into the waveguide. The proposed waveguide is 3D printed, and its internal faces are covered by copper tape to maintain a low weight (less than 0.5 lb.). The prototype is experimentally tested, and the results confirm the prototype’s functionality from 2.1 GHz to 3.6 GHz with a bandwidth of 52.6 % and a peak gain of 8.5 dBi. Furthermore, the high-power handling capability of the proposed design has been experimentally confirmed by exciting it with a 7 kV pulsed source. These results demonstrate the applicability of the proposed antenna in satellite communication, radar communication, and wireless communication between Unmanned Aerial Vehicles (UAVs).

“…Among these approaches is the utilization of MSs which have shown great efficacy in producing and enhancing CP radiation. As a result, numerous antennas incorporating MSs have been created and successfully demonstrated wideband CP capabilities [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 ]. However, these uniform MS designs are limited in their ability to effectively enhance bandwidth and improve gain, which results in narrow applicability.…”

In this paper, a patch array antenna with wideband circular polarization and high gain is proposed by utilizing a hybrid metasurface (MS). A corner-cut slotted patch antenna was chosen as the source due to the possible generation of CP mode. The hybrid MS (HMS), consisting of a receiver MS (RMS) arranged in a 2 × 2 array of squared patches and a linear-to-circular polarization conversion (LCPC) MS surrounding it was then utilized as the superstrate driven by the source. The LCPC MS cell is a squared-corner-cut patch with a 45° oblique slot etched, which has the capability for wideband LCPC. The LCPC unit cell possesses wideband PC capabilities, as demonstrated by the surface current analysis and S-parameter simulations conducted using a Floquet–port setup. The LP EM wave radiated by the source antenna was initially received by the RMS, then converted to a CP wave as it passed through the LCPC MS, and ultimately propagated into space. To further enhance the LCPC properties, an improved HMS (IHMS) was then proposed with four cells cut at the corners, based on the original HMS design. To verify this design, both CMA and E-field were utilized to analyze the three MSs, indicating that the IHMS possessed a wideband LCPC capability compared to the other two MSs. The proposed antenna was then arranged in a 2 × 2 array with sequential rotation to further enhance its properties. As demonstrated by the measurements, the array antenna achieved an S11 bandwidth of 60.5%, a 3 dB AR bandwidth of 2.85 GHz, and a peak gain of 15.1 dBic, all while maintaining a low profile of only 0.09λ0.

“…In [14], a quadri-cluster CP sequentially-rotated MTS-based antenna array achieves an IBW of 84.74% (4 -9 GHz) and 3-dB ARBW of 57.6% (4.2 -7.6 GHz). In [15], a Z-shaped MTS-based CP fabrypérot antenna achieves an IBW of 64% (4.4 -7.6 GHz) and 3-dB ARBW of 18% (4.4 -5.3 GHz). In [16], a staircaseshaped MTS-based CP antenna achieves an IBW of 67.3% (4.1 -7.6 GHz) and 3-dB ARBW of 15.9% (4.8 -5.7 GHz).…”

This research proposes a quadruple-cluster leaf-shaped metasurface (MTS)-based circularlypolarized (CP) stacked-patch antenna array with hybrid coupler feed network for sub-6 GHz 5G applications. In the study, the leaf-shaped MTS-based CP stacked-patch antenna is characterized by characteristic mode analysis (CMA). In the antenna design, one cluster of the quadruple-cluster leaf-shaped MTS-based antenna array consists of 4 × 4 leaf-shaped MTS elements; and the hybrid coupler feed network is used to enhance impedance bandwidth (IBW), axial ratio bandwidth (ARBW), and antenna gain. Simulations are carried out and an antenna prototype is fabricated and experiments undertaken. The measured IBW, ARBW, and maximum gain at the center frequency (4 GHz) are 62.5% (3.4 -5.9 GHz), 21% (3.8 -4.54 GHz), and 9.04 dBic at 3.9 GHz. The novelty of this research lies in the use of: (i) the CMA concept to design and develop the leaf-shaped wideband MTS-based stacked-patch antenna with CP radiation pattern; and (ii) a low-complexity hybrid coupler feed network to enhance the IBW, ARBW and gain.INDEX TERMS Antenna arrays, characteristic mode analysis, couplers, metasurfaces, wideband.
