Abstract :
The stub-loaded ridge rectangular leaky waveguide, which consists of a ridge rectangular waveguide with an asymmetrically located stub guide is a candidate for millimetre-wave antennas. We design a leaky-wave antenna with 30 dB sidelobes based on the stub-loaded ridge waveguide and verify its validity numerically and experimentally.
