ABSTRACT:
A multi-band antenna comprising a device which is capable of functioning during at least a lower frequency band of operation and at least a higher frequency band of operation. The antenna comprises an elongated radiating element having a helical radiating element connected to one end thereof with one end of the helical radiating element being received by a non-conductive insulator. An outer conductive shell embraces the non-conductive insulator and at least partially encloses a portion of the helical radiating element. The straight radiating element acts as the antenna radiator during both the high and low frequency bands of operation.
