LOW POWER PASSIVE MIMO SURFACE USING APERTURE TYPE RADIATORS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240106500 titled 'LOW POWER PASSIVE MIMO SURFACE USING APERTURE TYPE RADIATORS
Simplified Explanation
The patent application describes designs and control techniques for passive multiple-input multiple-output (PMIMO) surfaces, including an array of reconfigurable reflective elements with varactor diodes for controlling polarization.
- Each unit cell in the array consists of a cross-slot radiating element, a first varactor diode for controlling polarization in one plane, and a second varactor diode for controlling polarization in another plane.
- A controller is connected to the varactor diodes to provide control signals for varying the direction of a reflected signal.
Potential Applications
The technology could be used in smart antennas, wireless communication systems, radar systems, and satellite communication systems.
Problems Solved
The technology allows for dynamic control of the direction of reflected signals, enabling improved signal reception and transmission in various applications.
Benefits
