  • Publication number: 20250030157
    Abstract: A radio frequency device comprises: a substrate; a conductive circuit that is configured to transmit a signal and comprises a plurality of transmission line segments on the substrate; and a decoupling element on the substrate positioned between adjacent first and second transmission line segments, the decoupling element comprising a first arm adjacent to the first segment of transmission line, a second arm adjacent to the second segment of transmission line, and a connecting portion connecting the first and second arms. The decoupling element is configured to reduce coupling between the first and second transmission line segments.

  • Patent number: 11342668
    Abstract: Antenna arrays include a first plurality of radiating elements in a first column thereof, which are responsive to a first plurality of RF feed signals derived from a first radio, and a second plurality of radiating elements in a second column thereof, which are responsive to a second plurality of RF feed signals derived from a second radio. A power divider circuit is provided, which is configured to drive a first one of the radiating elements at a first end of the second column of radiating elements with a majority of the energy associated with a first one of the first plurality of RF feed signals, and drive a first one of the radiating elements at a first end of the first column of radiating elements with a non-zero minority of the energy associated with the first one of the first plurality of RF feed signals.

  • Patent number: 10840607
    Abstract: Antenna arrays include first and second radiating elements, which are responsive to respective first and second hybrid radio frequency (RF) signals, and a power divider circuit. The power divider circuit is configured to generate the first and second hybrid RF signals as power-reduced combinations of first and second RF input signals received at input terminals thereof. For example, the first hybrid RF signal may be generated as a combination of a 70-90 percent energy contribution of the first RF input signal with a 0.26-2.7 percent energy contribution of the second RF input signal. Similarly, the second hybrid RF signal may be generated as a 70-90 percent energy contribution of the second RF input signal with a 0.26-2.7 percent energy contribution of the first RF input signal.
