ACAG1204-433-T is a 433 MHz ceramic chip antenna designed for ISM band wireless communication applications. The antenna is manufactured using LTCC (low temperature co-fired ceramic) technology and features a compact profile of 12.0 x 4.0 x 1.6 mm with an omni-directional radiation pattern and linear polarization. Key electrical characteristics include a bandwidth of 10 MHz, return loss of -6.5 dB, VSWR =2.0, 50O impedance, and peak gain of -1.72 dBi, with an efficiency of 35% at the center frequency. The antenna operates reliably across a temperature range of -55°C to +125°C and is RoHS II compliant, making it suitable for RFID, SigFox, LoRa, IoT, medical devices, smart meters, and remote monitoring applications.
