The Application of Choke Ring Antennas

Views: 296 Author: Site Editor Publish Time: Origin: Site

A choke ring antenna is an omnidirectional antenna designed for high frequencies (VHF & UHF). It consists of concentric conductive cylinders surrounding a central antenna. To protect it from the elements, the choke ring antenna is often enclosed in a radome or protective cover when installed outdoors.

The choke ring antenna is a high-performance GNSS antenna used for base stations, capable of tracking GPS, GLONASS, BeiDou, BeiDou Global, and Galileo systems. Its design meets the requirements for high precision and multi-system compatibility in measurement equipment. This antenna offers a stable phase center and high positioning accuracy for GPS applications. Additionally, the GNSS choke ring antenna includes specially designed filters that reduce multi-path signals in the L1 and L2 bands.

The choke ring antenna provides stable phase-center, offering accuracy at the millimeter level. Its choke ring structure effectively mitigates multipath interference and enables the tracking of low-elevation satellites. The antenna's radome is resistant to water, ice, snow, and dirt, allowing it to operate outdoors throughout the year.

Choke ring antennas are particularly notable for their ability to reject multipath signals, making them ideal for GPS and radar applications. In GPS ground-based receivers, choke ring antennas can provide precise measurements at the millimeter level, which is valuable for surveying and geological measurements.


The 3D choke ring antenna, equipped with multi-path suppression technology, effectively eliminates signal transmission errors. It also exhibits excellent anti-interference performance, suppressing unnecessary electromagnetic signals and preventing blockage from power grids, communication base stations, and radio stations. With its low elevation angle, high gain, good signal reception, and stable phase center, the choke ring antenna ensures sub-millimeter positioning accuracy. Currently, choke ring antennas are widely used in high-precision surveying and mapping, CORS stations, bridge and building deformation monitoring, and geological monitoring due to their sub-millimeter phase center stability.
