Benefits of technology
The patent is for a device that has two antennas (a transmit and a receive) on a substrate. The device also has circuitry that processes RF signals. The substrate is made of a material that reduces interference between the two antennas, improving the quality of the signals. The technical effect of this design is 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.

Embodiment Construction
[0070]Determining the location of an object or target (also referred to herein as localization) has an array of applications in a number of fields. For example, the ability to locate and / or track an object at very small scales (i.e., at high resolutions) facilitates advancement of numerous applications, and has wide spread applicability to a number of different fields. For example, the ability to accurately and precisely track an object or target in real-time has numerous benefits in the gaming industry and, in particular, for interactive video games. Object localization also has many applications in autonomous systems, such as autonomous vehicle navigation, exploration, robotics and human machine interaction. Virtual reality, motion tracking and capture and the like also benefit from the ability to locate and / or track object(s) accurately, robustly and in real-time or near real-time. Details of using localization techniques in a variety of applications are described in U.S. patent ...
