The 2108991-1 is a global LPWAN/ISM band helical antenna designed for surface-mount applications. It operates across a frequency range of 698-960 MHz with an omni-directional beamwidth, a VSWR of less than 3.5:1, and a feed point impedance of 50 ohms. This antenna handles up to 10 watts of continuous wave power and features easy tuning with four selectable frequency bands determined by the PCB pad layout. The compact component measures 18.00mm x 9.00mm x 1.57mm and is available in Tape & Reel packaging. Its design requires minimal matching circuits, making it ideal for various IoT, LPWAN, and ISM devices where a compact, globally-compatible antenna solution is needed.
