Differential signaling of antennas on a substrate

Abstract

A device comprising: a substrate; a transmit antenna fabricated on the substrate and configured to transmit radio-frequency (RF) signals; a receive antenna fabricated on the substrate and configured to receive RF signals; and circuitry, disposed on the substrate and differentially coupled to the transmit and receive antennas, and configured to provide to the transmit antenna RF signals to be transmitted by the transmit antenna and to process RF signals received by the receive antenna, wherein the substrate comprises material for reducing harmonic coupling between the transmit antenna and the receive antenna.

AI Technical Summary

Benefits of technology

The patent describes a device that has two antennas for receiving and transmitting RF signals. The device also has circuitry that processes RF signals. The device is made using a substrate that reduces interference between the two antennas. This results in better signal quality and more reliable communication.

Problems solved by technology

Generally, these conventional approaches are limited in application due to one or more deficiencies, including relatively poor or insufficient accuracy and / or precision, computational complexity resulting in relatively long refresh rates, environmental limitations (e.g., operation limited to outdoors, cellular or network access requirements and / or vulnerability to background clutter or noise), cost, size, etc.
