Horn Image-Guide Leaky-Wave Antenna
IEEE Transactions on Microwave Theory and Techniques, 1981A novel approach for designing a frequency-scanning millimeter-wave antenna is described. The antenna is constructed by using an image wide leaky-wave antenna embedded in a long trough with metal flares along both sides. The optimum flare angle for achieving maximum gain is theoretically predicted.
