Abstract

AbstractThis letter presents a new thin substrate‐integrated waveguide with twisted integrated–digitated capacitor‐based corrugations that offers a transmission loss < 0.55 dB. The presented waveguide operates at TE10 mode and is used to present a wideband beam‐scanning leaky‐wave antenna with an array of dumbbell‐shaped slots. The antenna is shown to operate at a frequency band of 25–37 GHz and offers a gain > 13 dBi throughout the frequency band. It has a frequency‐dependent beam‐scanning capability of 6 deg/GHz. The proposed antenna being thin is extremely conformal and is suitable for applications in millimetre‐wave off‐body communication.
