A multi-frequency band antenna includes a base and a first antenna array including a plurality of spaced apart monopole antenna elements extending outwardly from the base a first distance for operating at a first frequency. Further, the multi-frequency band antenna also includes a second antenna array including a plurality of spaced apart antenna elements arranged outside the first antenna array and extending outwardly from the base a second distance less than the first distance. The second antenna array may be for operating at a second frequency lower than the first frequency. <IMAGE> |
