Monopole Antennas Pulse Electronics Monopole Antennas are SMD-compatible and have omni-pattern radiation. These antennas feature 50Ω nominal impedance, linear/horizontal polarization, low profile, high efficiency, and high gain. The monopole antennas are RoHS compliant and MSL-Level 1 rated. Typical applications include 2G/3G, WLAN, BLUETOOTH®, remote monitoring, sensor networks, security, Internet of Things (IoT), and GPS.
