Abstract
A broadband antenna system including a frequency-dependent antenna and a frequency-independent antenna coupled to the frequency-dependent antenna. The antenna system can be arranged so that a dipole or monopole antenna is coupled to the inner or outer termination points of a spiral antenna. When the dipole antenna is coupled to the outer termination points of the spiral antenna, the elements of the spiral antenna may be extended.
