Electronic devices having communications and ranging capabilities

This electronic device uses multiple antennas to both communicate and measure distances to objects. It has a specific physical design with antennas built into layers of a circuit board. Specifically, it uses a four-layer substrate with ground traces and patch elements on the second layer to create antennas for communication and ranging, where some antennas transmit very high-frequency signals that reflect off objects, allowing the device to measure distances.

Why it matters: Filed before widespread mmWave 5G deployment. The integration of high-frequency antennas into compact devices has matured, making this specific layered antenna design more feasible for consumer electronics.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedCustom multi-layer PCB, antenna design, control circuitry
