Abstract

An 8x1 frequency scanning antenna array has been presented for its operation in the 255-330 GHz frequency band. The antenna has been implemented using WR-3 rectangular waveguide structures and power combiner waveguide-structures in brass metal using mechanical micro-milling facilities. The antenna has been measured using a vector network analyzer and two 220-330 GHz frequency extender heads. The obtained steering range while varying the operation frequency in the 255-330 GHz range has exceeded successfully the required steering range of Δθ = 40°.
