A 2-D frequency scanning array operating in the 220-320-GHz frequency band is presented.
The array is composed of 64 open-ended rectangular waveguides arranged in an 8× 8
configuration. The feeding circuit comprises two waveguidebased phase shifting networks,
which provides the required phase shift between adjacent radiating elements when the
working frequency is modified. The array was manufactured over brass sheets through a
mechanical procedure and experimentally characterized, providing beam steering along a …

A 2-D frequency scanning array operating in the 220-320-GHz frequency band is presented. The array is composed of 64 open-ended rectangular waveguides arranged in an 8 × 8 configuration. The feeding circuit comprises two waveguidebased phase shifting networks, which provides the required phase shift between adjacent radiating elements when the working frequency is modified. The array was manufactured over brass sheets through a mechanical procedure and experimentally characterized, providing beam steering along a 50° × 45° space region while the working frequency is swept between 220 and 320 GHz, with a maximum -10-dB secondary lobe level and a measured 17-dBi gain at 275 GHz.
