Antenna & RF Services
From initial requirements to final optimized circuit board design, we help you design and optimize RF and antenna performance until it meets carrier certification standards.
Since 2015, we have been moving forward together with you.

Antenna and RF Services
HJ-Tech offers diversified wireless RF antenna solutions compatible with 4G/3G/2G, GNSS, Wi-Fi, Bluetooth, and other RF systems.
Since its founding, Henggu has focused on the R&D and manufacturing of RF connectors, industrial connectors, microwave antennas, and industrial harnesses. It is an antenna manufacturer that integrates R&D, production, and sales. The company operates internationally advanced fully automated production lines along with stamping and injection-molding workshops, has passed ISO 9001 / ISO 14001 and other system certifications, and serves as a long-term, stable supplier to multiple global leaders in photovoltaic energy storage, wireless video transmission, TV, and related industries.

Our Antenna Technology
We develop and manufacture multiple series of high-performance RF antennas that fully support 2G/3G/4G LTE cellular mobile communications, compatible with both FDD and TDD network modes, enabling long-distance voice, SMS, and high-speed wireless data transmission. They also support multi-system GNSS satellite positioning and timing, compatible with GPS, BeiDou, GLONASS, and Galileo, delivering accurate positioning and time synchronization through high reception sensitivity. Our products also cover Wi-Fi (2.4 GHz / 5 GHz) and Bluetooth BLE short-range wireless connectivity, meeting the needs of high-speed LAN interconnection and low-power sensor data acquisition scenarios.
We offer PCB onboard antennas, FPC flexible embedded antennas, ceramic dielectric antennas, external rubber duck antennas, suction-cup mount antennas, and multi-in-one composite antenna solutions integrating multiple RF functions—all available with customizable dimensions, frequency bands, gain levels, and feeder interfaces, significantly simplifying the host device structural design and saving internal space.
