APAKN2504-C2G-T is a GPS/Galileo and GLONASS ceramic patch antenna designed for multi-constellation satellite positioning systems. The antenna operates at 1575.42 MHz (GPS/Galileo) and 1602 MHz (GLONASS) with a peak gain of 3.6 dBi and right-hand circular polarization (RHCP), providing reliable signal reception across both frequency bands. It features a compact 25.0 × 25.0 × 4.0 mm form factor with 50 O impedance and a frequency temperature coefficient of 20 ppm/°C, ensuring stable performance across temperature variations. The antenna is RoHS/RoHS II compliant with MSL = 1 rating, making it suitable for IoT, remote monitoring, M2M applications, and other GNSS-enabled systems requiring miniaturized, high-performance positioning solutions.
