Spectrum has developed high-performance radome antenna assemblies designed for plug-and-play use in ISM, satellite and WiFi applications. The AR series antenna assemblies feature a patch antenna mounted on an optimised ground plane with a pigtail cable to a connector, which is tuned and packaged for the plastic radome that covers the complete assembly. These antennas are available in three basic antenna sizes – AR25, AR45 and AR78 – and include industry-standard cables such as RG-316 to MMCX or SMA connectors, with other options available.
By incorporating a highly efficient 25 x 25 mm ceramic antenna element, the AR25 series is well suited for satellite-based antenna applications such as GPS, GlobalStar and Iridium. It operates between 1500 and 1700 GHz and with its small size of 4,50 x 4,50 x 1,27 cm is suitable for a variety of GPS applications, including military drones and bots, asset tracking and other types of locations services, and timing applications such as cellular base stations and traffic control timing.
The AR45 series is versatile due to its wide range of operational frequencies and gain profiles, with a peak gain of 3 to 6 dBic. Designed for high-gain GPS applications as well as medium- to high-gain WiFi applications, the antenna is a suitable choice for GlobalStar and Iridium designs. Measuring just 7,14 x 7,14 x 2,25 cm, the AR45 works for applications such as location services, industrial and utility timing control, asset tracking, short burst data, RFID, local area wireless networks, and other high performance WiFi applications.
Dedicated to the 868 MHz and 915 MHz ISM bands, the AR78 series is ideal for medium- to high-gain applications including medical, industrial point-to-point communications, industrial data backhaul, RFID, municipal telemetry systems, forestry, mining, military applications and homeland security. The radome measures 11,11 x 11,11 x 2,21 cm.
