Electronic Devices with Dynamic Antenna Switching - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240097324 titled 'Electronic Devices with Dynamic Antenna Switching

Simplified Explanation

The abstract describes an electronic device with two antennas, a first antenna transmitting signals in a low band and a second antenna receiving signals from the first antenna through a feedback path. The device includes couplers, a low-pass filter, and control circuitry to switch between antennas based on a scattering parameter value.

• The device has a first antenna for transmitting signals in a low band and a second antenna for receiving signals from the first antenna.
• Couplers are used to couple signals from the first antenna to the second antenna, with a feedback path to a receiver.
• A low-pass filter is included on the second path to filter out unwanted signals.
• Control circuitry generates a scattering parameter value to determine when to switch between antennas for optimal coverage.

Original Abstract Submitted

an electronic device may be provided with a first antenna fed by a first path and a second antenna fed by a second path. a first coupler may be disposed on the first path, a second coupler may be disposed on the second path, and a feedback path may couple the couplers to a receiver. a low-pass filter may be disposed on the second path. the first antenna may transmit signals in a low band. some of the signals may couple onto the second antenna. the second coupler may pass the coupled signals to the receiver. control circuitry may generate a scattering parameter value characterizing the coupling of the signals from the first antenna onto the second antenna. the scattering parameter value may be used to determine when to switch the first antenna out of use and the second antenna into use for covering the low band.
