  • Patent number: 11626659
    Abstract: An embodiment an antenna unit of an antenna array includes a signal coupler, a phase-shifting modulator, and an antenna element. The signal coupler has a first input-output port, a second input-output port, and a coupled port. The phase-shifting modulator is coupled to the coupled port of the signal coupler, and the antenna element is coupled to the phase-shifting modulator via a connection remote from the signal coupler, or via an isolated port of the signal coupler. The phase-shifting modulator is configured for both relatively low signal loss and relatively low power consumption such that the antenna array can have significantly lower C-SWAP metrics than a conventional phased array while retaining the higher performance metrics of a conventional phased array.

  • Patent number: 11211716
    Abstract: An embodiment of an antenna includes first and second transmission lines, first antenna elements, and second antenna elements. The first transmission line is configured to guide a first signal such that the first signal has a characteristic of a first value, and the second transmission line is configured to guide a second signal such that the second signal has the same characteristic but of a second value that is different than the first value. The first antenna elements are each disposed adjacent to the first transmission line and are each configured to radiate the first signal in response to a respective first control signal, and the second antenna elements are each disposed adjacent to the second transmission line and are each configured to radiate the second signal in response to a respective second control signal. Such an antenna can have better main-beam and side-lobe characteristics, and a better SIR, than prior antennas.

  • Patent number: 11128035
    Abstract: In an embodiment, an antenna unit for an antenna array allows shifting the phase of a radiated or received signal without the need for a phase shifter, and includes an antenna element, switching devices, and signal couplers. The antenna element includes at least one section and signal ports each electrically isolated from each other and from each of the at least one section. The switching devices are each configured to couple a respective one of the signal ports to one of the at least one section in response to a respective control signal, and the signal couplers are each configured to couple a respective one of the signal ports to a respective location of a respective transmission medium.
