Abstract

We design and fabricate a double-layer hollow-waveguide slot array antenna with wide bandwidth and high antenna efficiency for the 120GHz band. The antenna is fabricated by diffusion bonding of laminated thin metal plates for high precision and perfect electrical contact. The 16×16-element antenna shows more than 70% antenna efficiency over a 13GHz bandwidth. Furthermore, it realizes error-free data transmission in 2.5m distance at up to 10Gbit/s. To our knowledge, this is the first report of the design and fabrication of a high-efficiency wideband planar antenna for the 120GHz band.
