摘要： In accordance with one or more embodiments, a dielectric coupler includes a neck portion configured to receive a first electromagnetic wave from a hollow waveguide. A flared portion is configured to generate, responsive to the first electromagnetic wave, a second electromagnetic wave along a surface of a transmission medium, wherein the flared portion at least partially surrounds the transmission medium, wherein the second electromagnetic wave propagates along the surface of the transmission medium without requiring an electrical return path. A tapered portion is configured to interface the neck portion to the flared portion.

摘要： A vehicle having a communication system is disclosed. The system includes two electrical couplings, coupled by way of a rotary joint. Each electrical coupling includes an interface waveguide configured to couple to external signals. Each electrical coupling also includes a waveguide section configured to propagate electromagnetic signals between the interface waveguide and the rotary joint. Additionally, the rotary joint is configured to allow one electrical coupling to rotate with respect to the other electrical coupling. An axis of rotation of the rotary joint is defined by a center of a portion of the waveguides. Yet further, the rotary joint allows electromagnetic energy to propagate between the waveguides of the electrical couplings.

摘要： A polarizer apparatus for RF communications including an in-line waveguide switch having a first port with a rectangular waveguide shape, and a second port having a circular waveguide shape. The waveguide switch includes a plurality of rotatable disks coupled and arranged between the input and output of said waveguide switch, each of the disks having an opening provided therein which defines at least a portion of a signal path configured to allow RF signals to propagate therethrough. The waveguide switch includes an actuating mechanism arranged to rotate the disks to positions relative to each other which modify the polarization of RF signals propagating through the openings. The polarizer apparatus includes a feed coupled to the output of the waveguide switch, the feed including a vane polarizer arranged to circularly polarize signals provided thereto from the output of the waveguide switch.

摘要： A rotary coupling includes a first waveguide, a second waveguide that is coaxial with the first waveguide and supported for rotation relative to the first waveguide, and a collar. The collar is connected to one of the first and second waveguides and extends circumferentially about an end of the other of the first and second waveguides to reduce attenuation of electromagnetic radiation conveyed between the first waveguide and the second waveguide.

摘要： An antenna array assembly is described herein. The assembly includes a housing, a plurality of antennas arranged in an array, an antenna switcher in communication with the array and a tuner. The tuner is in communication with the antenna switcher. The tuner has a memory and a channel look-up table contained therein. The look-up table has a remembered association between an optimal signal associated with each channel of the tuner and one of the plurality of antennas. The tuner is configured to automatically select from the look-up table only one of the plurality of antennas that has detected the optimal signal associated with the channel. When that channel is selected by a user the tuner instructs the antenna switcher to switch to the single antenna that is detecting the optimal signal in accordance with the look-up table.

摘要： A guided wave radar fluid level measurement system can measure the level of product in a tank. A pulse of RF energy sent along a waveguide in the tank can be reflected where the waveguide enters the product. A time of flight measurement can indicate the product level. The product inside the tank can flow and that flow can push the waveguide and thereby torque and possibly bend the waveguide. A streamlined wave guide is torqued less when the streamlining is aligned with the direction of flow. A rotating connector can provide for the waveguide to rotate and a weathervane effect can align the streamlined waveguide with the flow.
