“…A multi-beam antenna based on spoof SPPs mode coupling has been reported in Ref. [85], where the antenna structure consists http://engine.scichina.com/doi/10.1016/j.scib.2019.01.022 of a feed monopole and N double-side corrugated metallic strips circling around the feed. The feed fields are coupled into spoof SPP waves propagating along the strips and radiating at the end, which divides the omnidirectional radiation pattern into several beams.…”

“…However, SPPs cannot be excited effectively on flat metallic plate at lower frequencies. To overcome this obstacle, artificial structured surfaces decorated by periodic grooves, slits, or holes have been studied to support and propagate spoof SPPs (SSPPs), which have similar properties of SPPs at optical frequencies [6][7][8][9]. Recently, the ultra-thin corrugated metallic strip (CMS) fed by a coplanar waveguide has been investigated by both simulation and experiment, which can realize broadband and high-efficiency conversion from the guided wave to SSPPs [10][11].…”

We propose novel wide-angle frequency scanning metasurface antenna and antenna array fed by spoof plasmonic waveguide. The spoof plasmonic waveguide adopts the ultra-thin corrugated metallic strip which can support and propagate spoof surface plasmon polariton (SSPP) with high efficiency. By compensating the momentum difference between SSPP and free-space propagation modes via constant phase gradient, metasurface antenna can exhibit wide-angle and continuous radiation property according to the Generalized Snell's law. A prototype is designed, fabricated and measured, which consists of a wideband polarization rotating transmissive phase gradient metasurface (TPGM) placed a certain distance above spoof plasmonic waveguide. Such antenna works in a wideband range from 6.8 to 14.0 GHz, and the main beam can continuously scan from the forward direction to the backward direction with high efficiency. The measured results show that the scanning angle can reach 55°, which agree well with the simulated and theoretically calculated results. Furthermore, the proposed metasurface antenna can be combined easily as an antenna array with a simple feed network. Compared to single metasurface antenna, the antenna array exhibits the pencil-shaped directional radiation property, and the average gain of antenna array is obviously enhanced. The proposed frequency scanning metasurface antenna is of great value in the design of conformal antenna and the large aperture antenna array, especially on curved faces.

This article presents and validates a leaky‐wave antenna by using the spoof surface plasmon polariton (SSPP) technique. By properly designing the proposed SSPP unit, the SSPP wave can be switched between the confinement and radiation modes. A large radiation efficiency can be achieved by properly designing the modulation depth, which ensures that a compact SSPP leaky‐wave array can be realized by using a small number of SSPP radiation units. To verify the design, a prototype which consists of a SSPP feeding network and a 4 by 4 SSPP radiation units has been fabricated by using a low cost FR‐4 substrate. A good agreement between simulated and measured results has been obtained. The proposed array antenna shows the promising capability of the SSPP technique for leaky‐wave antenna applications.
