A Frequency-Scanning Substrate-Integrated-Waveguide Meanderline Antenna for Radar Applications at 60 GHz

A Frequency-Scanning Substrate-Integrated-Waveguide Meanderline Antenna for Radar Applications at 60 GHz

By Marcus C. Walden

Abstract: This paper describes the design and characterization of a frequency-scanning meanderline antenna for operation at 60 GHz. The design incorporates SIW techniques and slot radiating elements. The amplitude profile across the antenna aperture has been weighted to reduce sidelobe levels, which makes the design attractive for radar applications. Measured performance agrees with simulations, and the achieved beam profile and sidelobe levels are better than previously documented frequency-scanning designs at V and W bands.
