## **Overview** 

Amphenol RF offers a wide variety of internal FPC and PCB antennas designed for use inside connected devices. The antennas feature either a flexible pad or rigid printed circuit board which can be mounted inside a device. These antennas are commonly terminated to wireless modules featuring AMC or compatible ultraminiature connectors. 

Internal antennas typically have a dipole design but are also available in both monopole and F-Type configurations. Common uses include tablets, autonomous or robotic appliances and portable entertainment devices.
