摘要： The present disclosure relates to an oscillator apparatus comprising a differential transmission line forming a closed loop, a plurality of active core components that are electrically connected to the differential transmission line and that are configured to compensate for loss in the differential transmission line, a plurality of tuning elements that are electrically coupled with the differential transmission line, and a processor configured to control each tuning element of the plurality of tuning elements to activate or deactivate such that an effective electrical length of the differential transmission line is changed.

摘要： Scalable 2D joint phase-time arrays (JPTA) support multiple simultaneous RF beams without sacrificing array gain. A 2D JPTA comprises M antenna groups that each comprise N antennas, each coupled to one of N phase shifters. The array comprises M delay elements configured to: apply a time delay to a first signal to be transmitted by one of the antenna groups while each phase shifter in the group phase shifts the time-delayed first signal and feeds the phase-shifted-and-time-delayed first signal to the corresponding antenna, or apply the time delay to a second signal received from the group while each phase shifter phase shifts a third signal received from the antenna, the second signal being a combination of the phase-shifted third signals. The time delays produce a beam spread in a first dimension of the array such that multiple beams are formed in different directions.
