Antenna system

An antenna system, comprising plural antennas, wherein:

• each antenna is different than every other antenna;
• each antenna is characterized by a principal plane;
• a principal plane of a first antenna is substantially parallel to a principal plane of a second antenna;
• the second antenna includes an insulating substrate extending in the principal plane of the second antenna;
• the second antenna further includes a radiating element, a ground conductor, a coupler having first and second signal conductors and a feed;
• the first signal conductor is coupled to the radiating element;
• and
• the second signal conductor is coupled to the ground conductor;
• wherein:
• the first antenna includes a planar shaped first insulating substrate extending in the principal plane of the first antenna;
• the first antenna further includes a first coupler having first and second signal conductors;
• the first antenna further includes a wire wound in plural turns around the first insulating substrate and having a first end coupled to the first signal conductor;
• and
• the first antenna further includes a tap conductor coupled between the second signal conductor and a predetermined one of the plural turns of the wire.

An antenna system comprising plural antennas, wherein:

• each antenna is different than every other antenna;
• each antenna is characterized by a principal plane;
• a principal plane of a first antenna is oblique to a principal plane of a second antenna;
• the first antenna includes a first insulating substrate extending in a principal plane of the first antenna;
• the first antenna further includes a first coupler having first and second signal conductors;
• the first antenna further includes a wire wound in plural turns around the first insulating substrate and having a first end coupled to the first signal conductor;
• and
• the first antenna further includes a tap conductor coupled between the second signal conductor and a predetermined one of the plural turns of the wire.

A method comprising:

• measuring a spatial performance and a spectral performance of an antenna system;
• analyzing the spatial performance and the spectral performance;
• adjusting a rotational location or spatial separation of an antenna in the antenna system when the spectral performance fails to meet spectral requirements;
• adjusting the antenna in the antenna system when the spectral performance fails to meet spectral requirements, and
• adjusting within the antenna system by spatial separation and rotational location in order to achieve spatial and spectral matched performance.
