Sažetak
One of interesting applications of backward-wave propagation deals with leaky-wave radiating structures with back-fire to end-fire scanning capabilities. However, majority of published designs are in planar technology, thus they are unsuitable for high-power applications. In this report, the main problems in design of high-power leakywave antenna are highlighted and the waveguide antenna based on a chain of the resonant-slot coupled cavity chain is proposed. Preliminary numerical and experimental results revealed scanning angle greater than ± 20 degrees from the broadside for the seventeen unit cells long waveguide with a longitudinal slot.
