Electronic Device with Charging-Coil Independent Rear-Facing Antenna - A simplified explanation of the abstract

This abstract first appeared for US patent application 18324835 titled 'Electronic Device with Charging-Coil Independent Rear-Facing Antenna

Simplified Explanation

The patent application describes an electronic device with conductive sidewalls and a rear wall, which has a cavity for housing a sensor board and a coil structure. The device also includes an antenna with an antenna ground and a patch element separated by an antenna volume. The patch element consists of conductive traces on the rear wall and the sensor board, connected by a conductive interconnect structure. The coil structure is positioned outside of the antenna to minimize any negative impact on antenna performance.

• The electronic device has conductive sidewalls and a rear wall.
• The rear wall is divided into a first portion and a second portion, creating a cavity.
• A sensor board is mounted within the cavity.
• A coil structure is also mounted within the cavity, surrounding the sensor board.
• The antenna has an antenna ground and a patch element, separated by an antenna volume.
• The patch element includes conductive traces on the rear wall and the sensor board.
• A conductive interconnect structure connects the conductive traces on the rear wall and the sensor board.
• The coil structure is positioned outside of the antenna to minimize any negative impact on antenna performance.

Potential Applications

This technology can be applied in various electronic devices that require both a sensor board and an antenna, such as smartphones, tablets, wearables, and IoT devices.

Problems Solved

1. Minimizes the impact of the coil structure on the performance of the antenna, ensuring optimal wireless communication. 2. Provides a compact design by utilizing the rear wall for both the antenna patch element and the cavity for the sensor board and coil structure.

Benefits

1. Improved wireless communication performance due to the separation of the coil structure from the antenna. 2. Space-efficient design, allowing for the integration of a sensor board and coil structure within the device. 3. Enhanced functionality and versatility of electronic devices by combining sensor capabilities with wireless communication.

Original Abstract Submitted

An electronic device may have conductive sidewalls and a rear wall. The rear wall may have a first portion mounted to the sidewalls and a second portion protruding away from the first portion to define a cavity. A sensor board may be mounted within the cavity. A coil structure may be mounted within the cavity and surrounding the sensor board. An antenna may have an antenna ground separated from a patch element by an antenna volume. The patch element may include a first conductive trace on the first portion of the rear wall, a second conductive trace on the sensor board, and a conductive interconnect structure that couples the first conductive trace to the second conductive trace. The coil structure may be disposed outside of the antenna to minimize impact of the coil structure on performance of the antenna.
