The PRO-IS-212 is a compact board antenna designed for cellular 2G/3G/GSM and LPWA LoRa/SigFox connectivity. It features dual-band operation covering 868–960 MHz and 1710–1990 MHz with linear polarization and a peak gain of up to 2.9 dBi in the lower band and 1.9 dBi in the upper band, delivering radiation efficiency exceeding 37% and 51% respectively. The antenna measures 50 × 8 × 0.8 mm with a 100 mm coaxial cable terminated in an MHF-1 (F) connector, mounted via adhesive for easy integration onto PCBs. Operating reliably from -40°C to +85°C with 50 O impedance and return loss better than -3.5 dB, it is well-suited for IoT, M2M, industrial infrastructure, smart metering, and broadband cellular connectivity applications.
