No, you can't uninstall the application because it's part of the system apps which means you will need superuser access to do it. The ANT Radio Service provides wireless communication with devices that are using this technology.
By default, the ANT+ works with the following devices:
-Samsung S Health
-SportsTracker by STL
-Run.GPS Trainer UV
-IpBike, IpWatts, IpPeloton, IpSmartHr
However, if you're not using any of the devices above or the technology itself, long tap on its icon, then drag it to App Info. Tap again on Force Stop and Disable. You might need to repeat the process in case you want to use a device from the above list.
