A multi-band antenna having a common feed

摘要

A multi-band antenna is provided with a common feed. The antenna includes a vertically oriented elongated support structure. A first frequency selective radiating element is carried by the structure and is optimized for radiating a first RF signal having a first frequency from a first frequency band. A second frequency selective radiating element is carried by the structure and is optimized for radiating a second RF signal having a second frequency from a second frequency band. The frequencies within the first frequency band differ from the frequencies in the second frequency band. A common signal feed is carried by the structure for simultaneously carrying both the first and second RF signals for application to the radiating elements.
