The 2118900-1 is a compact surface-mount GNSS antenna designed for global navigation satellite system applications within the 1560–1602 MHz frequency band. It features a linear polarization with omnidirectional azimuth beam width, a VSWR of less than 2.0:1, and a 50 ohm feed point impedance, ensuring efficient signal reception across the operating frequency range. The antenna measures 10 mm × 10 mm × 1 mm and weighs less than 0.5 g, making it ideal for space-constrained applications. With a power handling capability of 3 watts continuous wave and an operating temperature range of -40°C to +85°C, this antenna is well-suited for portable navigation devices, IoT applications, and embedded GNSS receivers where compact form factor and reliable performance are essential.
