High-Performance PCB Coaxial Antenna

Standard Product

The High-Performance PCB Coaxial Antenna is an omnidirectional Dipole Antenna designed for 800–900 MHz and 2 GHz bands to meet IoT application requirements. A 120 mm radiating element optimizes performance in the 800–900 MHz band, improving signal propagation around obstacles.

The antenna operates independently of the Ground Plane, enabling easy integration by directly connecting to a communication module via an RF connector. It delivers high Radiation Efficiency across all supported bands. When installed in plastic dielectric enclosures, antenna performance remains stable if mounted at least 10 mm away from metal surfaces, with 20 mm recommended for optimal results.

This Embedded Dipole Antenna provides stable signal transmission and extended communication range across supported frequency bands. It supports a wide range of IoT and M2M applications requiring reliable wireless connectivity.

Features

1. Pre-Certified for Integration with Multiple Communication Modules

Certified for use with major communication modules distributed in Japan, enabling immediate prototyping and mass production even under tight development schedules.
Supports Japan’s primary cellular frequency bands, including 800–900 MHz and 1.4–2 GHz. Suitable for 4G LTE, LPWA in the 902–928 MHz ISM band (FCC Part 15 equivalent in Japan), and GPS/GNSS applications.

2. Superior Antenna Performance

Designed to achieve high Radiation Efficiency across a wide frequency range. Operates independently of the Ground Plane and connects directly to communication modules using a coaxial cable and RF connector.
To minimize performance degradation, mount the antenna at least 10 mm away from metal surfaces, with 20 mm or more recommended for optimal performance. Delivers higher performance compared to antennas of similar size available on the market.

3. Comprehensive Engineering Support

Additional engineering support is available for antenna integration evaluation and implementation. For assistance, contact STAF Corporation or your authorized distributor.

Applications

Primarily deployed in smart tracking devices. The PCB Dipole Antenna is integrated into compact GPS/GNSS trackers and pet tracking devices to enable reliable location data transmission, asset tracking, and device status monitoring.
Also ideal for logistics management systems, agriculture and dairy monitoring terminals, LTE routers and gateways, and antennas for rental cars, car-sharing, and bike-sharing systems.
