RF Antennas

EXS148SM is a direct current (DC) blocked ultra wideband (UWB) antenna designed to work with high frequencies ranging from 3.1GHz to 11.5GHz for multiple applications. The antenna assembly features a printed circuit board (PCB) design with an integrated ball mount and spring base for installation.

Applications

The EXS148SM antenna can be applied to various applications like wireless communication, GPS navigation, remote sensing, UAVs and other applications in which the antenna is required to cover a large frequency range.

Specific applications of this antenna include:

• WiFi
• LTE/4G
• Bluetooth
• Zigbee & RFID
• GPS tracking
• Radar
• UAV navigation
• Video Surveillance
• Medical Imaging

Working Principle

The EXS148SM antenna works on the principle of using multiple elements to create an antenna array which can cover a wide frequency range. The antenna contains two flexible dipoles connected in parallel with each other. The antenna elements vibrate at different frequencies which combine to make a broad frequency range. The antenna also includes an active balun which matches the impedance of the antenna to the feed line.

In addition, the antenna assembly also contains a radome which acts as an additional layer of protection for the antenna elements. The radome also helps reduce the overall size of the antenna assembly without significantly impacting the performance of the antenna.

Conclusion

The EXS148SM is a UWB antenna assembly designed for use across multiple frequency applications. The antenna employs multiple elements to cover a wide frequency range. The antenna also contains an active balun to match the impedance of the antenna to the feed line as well as a radome for additional protection. As a result, the EXS148SM is suitable for multiple applications in which a UWB antenna is required.
