MULTI-BAND ANTENNA WITH A COMMON RESONANT FEED STRUCTURE AND METHODS

摘要

A multi-band antenna and associated apparatus for communication systems and other applications. In one embodiment, a common junction network is provided having a first and a second radiator. The first radiator resonates in a first frequency band. The second radiator resonates in a second frequency band. The first and second frequency bands are different from one another (yet may overlap). A first electrical component is coupled to the common junction network and proximately located to the first radiator. The first electrical component creates a resonance with the common junction network to create a third frequency band proximate to the first frequency band. The first radiator is capable of communicating RF energy in the first frequency band and the third frequency band.
