The 3DBI GSM/GPRS/3G PCB Antenna is a flat printed circuit board antenna that covers frequencies from 900 to 1500 MHz. PCB antenna means the radiating element is printed directly on a thin board — no coil, no metal rod. The 3dbi pcb antenna delivers a gain (signal amplification over a reference point) of 3 dBi, which gives noticeably better reception than the tiny chip antennas soldered directly onto GSM modules. It connects through an IPX13 (a small snap-on RF connector) and has a total length of 15cm, keeping it easy to fit inside enclosures.
The 3dbi gsm antenna works at 50 ohm impedance, which is the standard RF impedance for most GSM and GPRS modules. One non-obvious detail — PCB antennas are sensitive to nearby metal and ground planes. Placing this antenna flat against a metallic surface or right next to a battery will detune it and reduce gain noticeably. Keep at least 5mm clearance around the antenna edges. The operating temperature goes from -30°C up to +85°C, so field deployments in warm Indian summers are not a concern. One limitation to keep in mind — at 900 to 1500 MHz, it does not cover 1800 or 1900 MHz bands used by some 4G networks.
The 3dbi 3G PCB Antenna pairs with SIM800L, SIM900A, SIM800C, and similar GSM modules through the IPX connector. building SMS alert systems and engineers prototyping IoT field devices both use it regularly. To start, snap the IPX13 connector firmly onto your module’s U.FL port — it clicks into place. StemVolt provide this antenna tested and ready for direct use.
