The invention describes a portable communication device, like a smartphone, that uses a specialized internal circuit board to connect its wireless communication components to an antenna built into the device's housing. This circuit board has sections with varying flexibility and routes high-frequency signals using a signal line positioned between two ground lines. The claims specifically detail this multi-section PCB and its connection to a conductive side portion of the housing acting as an antenna.
Why it matters: Since 2023, the ongoing push for thinner mobile devices and the integration of more complex high-frequency wireless standards, such as advanced 5G and early 6G research, have intensified the need for compact, high-performance antenna integration and signal routing solutions like this specialized flexible-rigid PCB.
