Hi,

A choke ring antenna is typically used in GNSS receivers. What’s the radiating element inside? A dipole?
 
Hi,


A choke ring antenna is commonly used in GNSS applications to minimize multipath interference. The radiating element inside is typically a microstrip patch antenna or a quadrifilar helix, rather than a dipole. Patch antennas are widely used due to their compact size, circular polarization, and good impedance matching with GNSS signals.


Let me know if you’d like more details!
