The increased RF functions and antenna number is the trend of the modern laptop computer design to provide more features and performance. To combine the antenna design with the other component is a way to reduce the placement risk. The application of the combination might induce the antenna performance drop. To combine the antenna with fingerprint sensor as an example the antenna performance drop when user put their finger in the fingerprint sensor. This document will introduce an antenna invention to let fingerprint sensor as a part of the antenna radiation system and provide a secondary antenna performance from the fingerprint sensor when use put their finger on the fingerprint sensor.
