Note
1.
The antenna has built-in circuitry to the ground termination. Connecting
the antenna’s ground point to the system’s RF ground plane is optional. If
good matching is achieved, the ground termination is then used as a
solder joint (like S1, S2, S3, and S4) to fix the antenna to the substrate
only.
