摘要：
This 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.
