Multiband dipole antennas connected to a coaxial feeder are usually not balanced and are not operated at maximum efficiency. In the present invention pairs of capacitors are connected at the feed point of respective half-wave dipoles, associated with different frequency bands to reduce these deficiencies. A similar technique is useful for single band half-wave dipoles and allows unbalanced multiband ground plane antennas to be constructed. |
