Broadband convex ground planes for multipath rejection

An antenna system comprising:

• an antenna;
• a ground plane comprising:
• a convex conducting surface;
• and
• an array of conducting elements disposed on at least a portion of the convex conducting surface, and
• a system component comprising at least one of:
• a navigation receiver;
• a low noise amplifier;
• a signal processor;
• a wireless modem;
• and
• a sensor,
• wherein the system component is located within the convex conducting surface.

A ground plane comprising:

• a convex conducting surface;
• and
• an array of conducting elements disposed on a plurality of circles on at least a portion of the convex conducting surface, wherein:
• adjacent conducting elements disposed on a specific circle are separated by a specific increment of azimuth angle, the specific increments of azimuth angle are the same for all circles in the plurality of circles, a surface density of the array of conducting elements disposed on the specific circle is based at least in part on a specific corresponding meridian angle of a specific circle and is inversely proportional to the cosine of the specific corresponding meridian angle.
