Abstract
A leaky dielectric travelling wave surface waveguide antenna provides a multiband, low-profile antenna for satellite and other wideband (Ku/K/Ka/Q) communications applications. The antenna structure can be arranged into various types of arrays to yield a cost-effective, wideband/multiband operation with high power. In one implementation, the antenna includes a waveguide having a multi-layer substrate, a top surface, a feed (excitation) end, and a load end. One or more scattering features are disposed on the top surface of the waveguide or within the waveguide, and achieve operation in a leaky propagation mode. A wavelength correction element adds linear delay to incident energy received or transmitted by the antenna. The resulting structure permits a resulting beam direction of the antenna to be independent of the wavelength.
