STRUCTURE OF A PARABOLIC ANTENNA

摘要

The parabolic antenna includes a first radiating element, a second radiating element and a parabolic dish. The operating frequency of the first radiating element is different from the operating frequency of the second radiating element. The first radiating element and the second radiating element are disposed in front of the parabolic dish. Under different circumstances, the first radiating element and the second radiating element may operate simultaneously or non-simultaneously.
