PASSIVE MIMO DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240106520 titled 'PASSIVE MIMO DEVICE
Simplified Explanation
The patent application describes an apparatus for passive multiple input multiple output (MIMO) wireless communication, including a first RF transmission line, a first array of antennas, a switch array, and lens elements for signal modification.
