loop antenna (electronics)

Introduction：

Ring antenna a kind of antenna manufactured into a ring shape, generally used to receive and radiate magnetic fields, the test will be placed in the center of the test object or the center line of the ring antenna, you can get the low-frequency magnetic field interference data of the test object.

Classification:

There are many types of loop antennas manufactured depending on their use and testing methods, including active loop antennas, passive loop antennas, triple loop antennas, receiving loop antennas, transmitting loop antennas, handheld radiating loop antennas, Helmholtz loop antennas, and many other categories.
