Compact PCB Coaxial Antenna

Standard Product

The Compact PCB Coaxial Antenna is a high-performance Omnidirectional Dipole Antenna designed for IoT applications. It supports the 800–900 MHz band and 2 GHz band. The compact form factor enables integration into space-constrained devices. The design does not require a Ground Plane. Simply connect to the communication module via an RF connector for easy embedded installation.

Embedded Dipole Antenna.

Features

1. Pre-Certified as an Additional Antenna for Multiple Communication Modules

Certified with major communication modules in the Japanese market, enabling immediate prototyping and mass production even under tight development schedules.

Supports Japan’s primary cellular frequency bands, 800–900 MHz and 1.4–2.4 GHz. Suitable for 4G/LTE, 902–928 MHz ISM band LPWA applications, short-range wireless systems, and GPS/GNSS.

2. Compact Form Factor

This antenna achieves a compact 77 mm length by partially sacrificing performance in the 800–900 MHz band.

The upper frequency extends to 2690 MHz and supports LTE Band 41. Optimized for applications requiring coverage of specific frequency bands within a compact device design.

3. Comprehensive Technical Support

Additional technical support is available for antenna integration. Please contact STAF Corporation or your authorized distributor for further assistance.

Applications

Primarily used in smart tracking devices. This compact Embedded Dipole Antenna is integrated into small GPS/GNSS trackers and pet tracking devices for position data transmission, asset tracking, and device status monitoring.

Also suitable for logistics management systems, agriculture and livestock monitoring terminals, LTE routers and gateways, and shared mobility platforms including rental cars, car-sharing, and bike-sharing systems.
