1. A system for mounting in a nose section of a munition, comprising:
a guidance system defining a central axis and having a circumference and an outside surface;
a substrate having an inner edge and an outer edge and including a top surface and a bottom surface, and positioned adjacent to the outside surface of the guidance system; and
an antenna system including:
a first plurality of conductive segments positioned on the top surface of the substrate at a first radial distance from the inside edge of the substrate, one or more of the first plurality of conductive segments comprising curved conductive segments defining a first curvature; and
a second plurality of conductive segments positioned on the bottom surface of the substrate at a second radial distance from the inside edge of the substrate, one or more of the second plurality of conductive segments comprising curved conductive segments defining a second curvature, the second plurality of conductive segments positioned axially below the first plurality of conductive segments, such that a portion of the first plurality of conductive segments overlies a portion of the second plurality of conductive segments.
