The APARM2508S-SG3L5 is a multiband stacked patch antenna engineered for receiving signals from GPS (L1 and L5 bands), GLONASS, GALILEO, and BEIDOU systems. It features a dual stacked patch design with Right-Hand Circular Polarization (RHCP), a low maximum VSWR of 1.8, and a nominal impedance of 50 Ω. The antenna provides specific zenith gains, including 0.6 dBi for GPS L1, 0.5 dBi for GPS L5, 3.4 dBi for GLONASS, and 2.4 dBi for BEIDOU. Designed to operate over a wide temperature range from -40°C to +105°C, it is suitable for a variety of applications such as IoT, M2M, navigation, surveying, logistics, and precision transportation.
