DISPLAY ANTENNA - A simplified explanation of the abstract

This abstract first appeared for US patent application 18517546 titled 'DISPLAY ANTENNA

Simplified Explanation

The patent application describes a display antenna system that combines a display with an antenna array, allowing for the transmission and reception of signals through the use of light emitters and patch antennas.

• The display antenna includes a grid of light emitters and a grid of patch antennas superimposed on the display.
• A phase shifter is located between the light emitters and is connected to the patch antennas to shift signals for transmission and reception.

Potential Applications

This technology could be used in:

• Smart displays
• Communication devices
• IoT devices

Problems Solved

• Integration of antennas into display systems
• Efficient signal transmission and reception in a compact space

Benefits

• Improved signal quality
• Space-saving design
• Enhanced functionality of display systems

Potential Commercial Applications

• Smartphones with integrated antennas
• Smart home devices
• Wearable technology

Possible Prior Art

Prior art may include:

• Antenna systems integrated into electronic devices
• Display technologies with embedded sensors

Unanswered Questions

How does the phase shifter impact signal transmission?

The phase shifter is mentioned in the abstract, but its specific function and impact on signal transmission are not detailed. Further information on how the phase shifter operates would provide a clearer understanding of its role in the system.

What is the specific wavelength band of the visible region used in this technology?

The abstract mentions that the patch antennas transmit light in a wavelength band of a visible region, but the exact range or specific wavelengths are not specified. Knowing this information would help in understanding the capabilities and limitations of the technology.

Original Abstract Submitted

Provided is a display antenna including a display including a plurality of light emitters arranged in a grid, an antenna array having an antenna assembly in which a plurality of patch antennas through which light in a wavelength band of a visible region is transmitted is disposed in a grid, the antenna array being disposed to be superimposed on the display, and a phase shifter disposed in a gap region sandwiched between the plurality of light emitters, connected to at least one of the plurality of patch antennas, and configured to shift a signal to be transmitted and received.
