ABSTRACT:
A broadband antenna system includes a frequency-dependent antenna and a frequency-independent antenna rotatably coupled to the frequency-dependent antenna. The antenna system may be arranged such that a dipole or monopole antenna is rotatably coupled to the inner or outer termination points of a spiral antenna, which is, in turn, movably coupled to a base. When the dipole antenna is coupled to the outer termination points of the spiral antenna, the elements of the spiral antenna may be extended.
