Antenna description


The High-Efficiency Antenna Optimized for ISM

This 2J0B15-868 series connector mounts low profile ground plane-dependent antenna has been optimized specifically for the ISM frequency bands of 863MHz to 870MHz in the European market.
When selecting the correct antenna for the application, it is important to understand the restriction of the 868MHz ISM band. This antenna was developed for system installations such as industrial, scientific, and medical applications. IoT applications can also take advantage of this system as it provides high throughput and is not limited to any transmission time. IoT implementations can range from home automation, security, industrial control, remote sensing, automatic meter reading, toys, and weather stations among many other consumer applications.

Application Parameters

Based on the application’s needs, this antenna provides an average range of 800 meters. The 2J0B15-868 868MHz band antenna provides a stable connection through walls and transmission is not disturbed by obstacles such as human bodies (this is the case for WIFI and Bluetooth technologies at 2,4 GHz).
