AbstractIntegrating dual antennae into a single rigid assembly guarantees parallel alignment between the antennae and provides higher isolation with lower insertion loss than duplexing methods can achieve through a single antenna. The resulting higher performance at lower cost can benefit two-way communication systems using time division duplexing, frequency division duplexing, or polarization division duplexing; or combinations of these methods.
RLN's patent was granted unusually quickly, only 15 months from the final application to the Notice of Allowance. Moreover, all 20 claims were granted without a single office action.
The highly directional antennas used by a point-to-point link span distances orders of magnitude farther than can be acheived by omnidirectional antennas with the same transmitter power at the same frequencies. Adding redundant point-to-point connections requires additional directional antennas and equipment at both nodes; it is sometimes done, but is usually not cost effective.
