Patent ID: 7209091

Claim:
A linearly polarized adjustable dipole antenna, comprising: a first pair of substantially parallel and similarly oriented monopole elements, including: a first common section, substantially perpendicular to and joining bases of the first set of monopole elements, including an edge and an adjustable source first contact point; and an adjustably attachable first support; a second pair of substantially parallel and similarly oriented monopole elements, including an orientation opposite to the first pair of monopole elements and displaced from the first pair of monopole elements, including: a second common section, substantially perpendicular to and joining bases of the second pair of monopole elements, including a second edge and an adjustable source second contact point; and an adjustably attachable second support, wherein the first and second pair of monopole elements are substantially within a common plane and whose first and second edges are displaced from each other by a first gap to form a first set of dipole radiators, wherein the first set of dipole radiators are tunable by adjusting the first gap.
