ACR1504I3

Antennas RF Overview

The ACR1504I3 is a multi-band chip RF antenna manufactured by Abracon LLC, designed for surface mount applications. It operates across three frequency bands within the UHF range (300MHz to 1GHz), specifically targeting 433 MHz, 868 MHz, and 915 MHz ISM frequencies. The component features a maximum height of 0.047 inches (1.20mm) and utilizes solder termination. It exhibits a Voltage Standing Wave Ratio (VSWR) of 2 and an impedance of 50 Ohms. The antenna provides varying gain levels across its bands, including 1.75 dBi at 433 MHz, -4.4 dBi at 868 MHz, and 2.11 dBi at 915 MHz.
