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

This abstract first appeared for US patent application 17947006 titled 'Electronic Devices with Dynamic Antenna Switching

Simplified Explanation

The patent application describes an electronic device with two antennas, a first antenna for transmitting signals in a low band, and a second antenna for receiving signals. The device includes couplers, a feedback path, and a low-pass filter to manage the signals between the antennas and the receiver. Control circuitry uses a scattering parameter value to determine when to switch between the antennas for optimal coverage of the low band.

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.
