  • Planar antenna with multiple radiators and notched ground pattern
    Patent number: 7289068
    Abstract: An antenna consisting of a single small and lightweight package, where each radiating element operates independently with reduced interference among the radiating elements. An integrated multi-element planar antenna includes a ground pattern 2 with a notch 2b formed at an end 2a, first radiating element 3 placed on one side of the notch 2b and equipped with a feeder 5, and second radiating element 4 placed on the other side of the notch 2b and equipped with a feeder 5. For example, inverted F antennas are used as the first radiating element 3 and second radiating element 4. The first radiating element 3 and second radiating element 4 are placed symmetrically about the notch 2b such that separation distance will be the largest at locations where their radiation fields are the highest.
