Flexible and PCB patch antennas for cellular applications

12 September 2023

Amphenol RF has launched flexible and PCB patch antennas for use inside connected devices.

The antennas feature either a flexible pad or rigid printed circuit board which can be mounted inside the device. Flexible and PCB patch antennas are commonly terminated to wireless modules featuring the AMC or other industry-standard ultraminiature connectors. These types of internal antennas are often used in wireless applications such as WiFi enabled IoT technology and portable entertainment devices.

Flexible and PCB patch antennas are available in dual-band, multi-band, and wide-band configurations with WiFi 6E supported options with reliable frequency range up to 7.2GHz. These 50ohm antennas have a dipole design which has a relatively low profile and can be mounted in various locations and support standard cellular protocols which makes them well-suited for IoT, WiFi and LTE technology. These antennas use centre-fed micro-coax cables that terminate to an ultraminiature AMC connector. The extremely thin antenna features an adhesive mounting tape on one side for secure placement inside the device.

The antennas are compatible with a wide variety of standard RF interfaces. They are well suited for applications that require a wireless signal such as drones, navigation systems, payment terminals, etc.
