“…Therefore, an alternative explanation was put in terms of the leaky-wave theory [29], [30], complementing the plasmonic interpretation. These antennas have been demonstrated at millimeter-waves for automobile radar [31] and space research applications [7] as well as in the terahertz [32] and mid-infrared band for quantum-cascade lasers [33].…”

Abstract-Reducing the profile, footprint and weight of antennas embarked on aircrafts, drones or satellites has been a long pursued objective. Here we tackle this issue by developing a millimeter-wave 96 GHz elliptical Bull's-Eye antenna with offaxis radiation at 16.5º that has been fabricated by low cost 3D printing stereolithography, followed by metal coating. The theoretical basis for optimum off-axis operations is explained. Measurement results show an overall good agreement with simulations, displaying a gain of 17 dB and a 3.5º beamwidth (Eplane) at the operational frequency. The off-axis beaming enlarges the potential applicability of this technology with respect to the broadside beam solution.

“…central slot surrounded by annular corrugation), which was first presented in [15] and, soon after, in [6], by introducing a sinusoidal corrugation profile instead of the typical square corrugations or the recently investigated triangular corrugations [16]. A similar idea was also studied in [17], but there the surface was modulated by a sinusoidal spiral function, achieving a circularly polarized leaky wave antenna.…”

“…For comparison, the green dashed curve gives the simulation result of the flat metal structure without corrugation. It could be observed that the maximum radiation enhancement for the corrugated structures in the E-plane is about 12.52 dB compared to the flat metal structure, which means the subwavelength corrugated metal structure shaped the beams from the slit to broadside radiation 12 13 14 15 16 17 18 38 . The simulated gain of the corrugated structure at 17 GHz is about 17.6 dB, while the simulated gain of the flat structure is about 5.08 dB.…”

One-dimensional (1D) subwavelength corrugated metal structures has been described to support spoof surface plasmon polaritons (SPPs). Here we demonstrate that a periodically modulated 1D subwavelength corrugated metal structure can convert spoof SPPs to propagating waves. The structure is fed at the center through a slit with a connected waveguide on the input side. The subwavelength corrugated metal structure on the output surface is regarded as metasurface and modulated periodically to realize the leaky-wave radiation at the broadside. The surface impedance of the corrugated metal structure is modulated by using cosine function and triangle-wave function, respectively, to reach the radiation effect. Full wave simulations and measuremental results are presented to validate the proposed design.
