Self-Adhesive Flexible PCB Antennas

FPC Antennas (Flexible PCB) for Compact Wireless Integration

Self-adhesive flexible PCB antennas, also known as FPC antennas, provide a thin and adaptable solution for integrating wireless connectivity inside compact electronic devices. Their flexible construction enables the antenna to conform to suitable surfaces within the product enclosure, while self-adhesive mounting simplifies mechanical installation. As part of Antenova’s Internal Antennas portfolio, flexible PCB antennas give engineers greater freedom to position the antenna around the mechanical constraints of the finished device.

When should I choose a flexible PCB antenna?

FPC antennas are particularly suitable for devices where available internal space is limited or where a rigid antenna format would restrict mechanical design. Their thin, flexible construction enables installation on suitable flat or curved internal surfaces and allows the antenna to be positioned away from the main PCB when this benefits the overall product architecture.

Self-adhesive attachment simplifies assembly without requiring additional antenna mounting hardware. Antenova flexible PCB antenna solutions support wireless technologies including 5G, 4G LTE / NB-IoT, Wi-Fi and Bluetooth® and other frequencies depending on the selected antenna.

What influences flexible PCB antenna performance?

The antenna's position within the finished device remains critical to RF performance. Batteries, displays, metal components, PCB assemblies and enclosure materials located close to the antenna can influence impedance matching, efficiency and radiation characteristics.

Engineers should therefore consider antenna position, orientation, cable routing and the intended adhesive mounting surface early in the product design. Maintaining a controlled antenna location during production also helps achieve consistent RF performance between manufactured devices.

Typical applications

FPC antennas are well suited to asset trackers, healthcare devices, industrial IoT equipment, gateways, smart meters, monitoring systems, consumer electronics and other space-constrained connected products requiring low-profile internal wireless connectivity.
