  • Multiband current probe fed antenna
    Patent number: 7994992
    Abstract: A multi-band antenna comprising a conductive structure and a plurality of current probes coupled around the conductive structure. Each current probe is designed to receive and transmit in a substantially different frequency band than the other current probes. The current probes are positioned on the conductive structure so as to effectively create a plurality of transmit/receive antennas such that each respective antenna has a voltage standing wave ratio (VSWR) of less than or equal to approximately 3:1 for a given range within each respective frequency band.
