Phase-shifting and feeding device for base station antenna miniaturization
A recently granted patent (Publication Number: US12003037B2) discloses a phase-shifting and feeding device designed for use in base station antennas. The device comprises a metal cavity with a U-shaped groove structure and an opening, housing a phase-shifting circuit with signal terminals. A feeding network board includes a substrate with a ground plane and feeding circuit, forming a shielding cavity with the metal cavity. The device features feeding holes with feeding pads, allowing signal terminals to be connected to the feeding circuit through feeding wires. The ground plane can be a monolayer structure or include multiple metal layers connected through a via hole, ensuring efficient signal transmission while being insulated from the feeding circuit.
Furthermore, the patent details the integration of metal cavities to create shielding cavities for phase-shifting circuits, enhancing performance and reliability. The device's design includes pins, metalized slots, and grounding pads for secure connections, along with limit caps for precise alignment. Legs are strategically placed to facilitate the connection between signal terminals and feeding pads through feeding holes. The innovative structure of the phase-shifting and feeding device aims to optimize signal transmission in base station antennas, offering a robust and efficient solution for telecommunications infrastructure.
