The present disclosure is directed to a
signal hub configured to provide
signal isolation for various components within a compact electronic device. In some embodiments, the
signal hub includes a top shell, an antenna carrier, a top cooling plate, a
radio frequency (RF) board, and a middle cooling plate. The antenna carrier supports multiple antennas electrically coupled to the top cooling plate, creating RF shielding through a ground connection that isolates antennas from other RF board components. The top cooling plate includes RF decouplers to reduce over-the-air and current
coupling, enhancing signal isolation. The middle cooling plate features a side plate that electrically isolates power-delivering wires, reducing
noise. The top and bottom cooling plates also interacts with respective grounding tracks on the RF board, which provide a grounding path for
electrical isolation. The
system dissipates electromagnetic energy and minimizing
crosstalk to maintain stable communication between boards and antennas.
