High performance low profile antennas

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