Abstract: Antennas such as flat panel, leaky wave antennas with directional coupler feeds and waveguides are disclosed. In one example, an antenna includes a surface having antenna elements, a guided wave transmission line, and a coupling surface. The guided wave transmission line provides a guided feed wave. The coupling surface is between and separates the guided wave transmission line and the surface having antenna elements. The coupling surface controls coupling of the guided feed wave to the antenna elements. The coupling surface can also spatially filter the guided feed wave to provide a more uniform power density for the antenna elements. The guided feed wave can be a high power density electromagnetic wave or a density radially decaying electromagnetic wave.

Abstract: A device containing a radio-frequency (RF) liquid crystal (RFLC) mixture with improved performance is disclosed. In one embodiment, the improved performance includes high RF tuning, broad thermal operating ranges and low viscosity. In one embodiment, the device comprises an antenna comprising: an antenna element array having a plurality of antenna elements and each antenna element having a liquid crystal (LC) structure, wherein the LC structure comprises a mixture of one or more of the following: laterally functionalized with one or more of at least a proton, a hydrogen (H), or a heteroatom.
