Abstract
A leaky waveguide slotted traveling wave antenna having several elongated nonresonant slots (2) oriented with their long axes substantially orthogonal to the direction of propagation within waveguide (1) filled with a dielectric material having a dielectric constant greater than 1. The length (m) of each slot (2) gradually increases as one traverses the waveguide (1) along the direction of propagation, whereas the width (W) of the wall of the waveguide (1) in which the slots (2) are cut gradually decreases as one traverses the waveguide (1) along the direction of propagation. Any angle of radiation between 0.degree. and 135.degree., including endfire and broadside radiation, can be achieved. The width (w) of each slot (2) and the inter-slot spacing (d) can vary; the increase in slot length (m) can be non-uniform.
