Hi Kristiyan,

Generally, electromagnetic radiation is produced by a radiating element. In your case, it would be an antenna fed by a signal of a particular frequency in the operating bandwidth of the antenna. These antennas would be covered by a radome which will protect the antenna from the physical environment as well as increasing the directivity depending on the design. In your case, it looks like the cone structure is a radome, convering an antenna. Please check with your superiors or guides to get more information about the implementation.

Best regards,
Praneeth.
