High-Data-Rate and Resilient Wireless Links at W-band Enabled by All-Metal Spline Horns

Résumé

The self-healing property of Bessel beams (BBs) is used to create a robust wireless link at W-band, maintaining high data rates despite metallic obstructions within their nondiffractive range (NDR). This is demonstrated experimentally using a broadband launcher, which comprises a photonic transmitter and a spline-profile horn, by placing a circular metallic obstacle in the beam’s path. Field measurements show the BB profile remains intact after the obstacle over the 75–105 GHz band. Power transmission tests reveal a record broadband efficiency of up to 70% (-1.54 dB) at 99 GHz across distances of 10 to 30 wavelengths. Bit error rate and real-time communication tests confirm the link’s reliability, achieving error-free data transmission at 3 Gb/s using on-off keying modulation.
