Regularities of Frequency Scanning in Slotted Waveguide Antenna excited with slowed-down wave
The work is devoted to the questions of scanning in the antenna of traveling wave having a discrete system of radiators. The main attention is paid to the case when the phase velocity of the traveling wave is less then light velocity. The conditions of one-beam scanning in a sector of real angles are obtained. The scanning process is studied on the example of slotted waveguide with partial dielectric filling.
