Trimmed foursquare antenna radiating element

An antenna element, comprising:

• a dielectric layer;
• four radiating elements comprising two pairs positioned over a top side of said dielectric layer, said pairs positioned diagonal to each other,
• a first of said pairs comprising radiating elements each having at least two perpendicular sides and a second of said pairs comprising at least two radiating elements each having at least two perpendicular sides;
• and
• at least two feed points located near an inner portion of one of said first and second pairs.

An antenna element, comprising:

• a dielectric layer;
• four quadrilateral radiating elements comprising two pairs positioned on a top side of said dielectric layer, said pairs positioned diagonal to each other;
• four feed lines, one of said four feed connecting to a feed point on a corresponding one of said four quadrilateral radiating elements;
• and
• a slot positioned on each of said four quadrilateral radiating elements.

A scannable array of radiating elements, comprising:

• a plurality radiating elements arranged in a geometrically shaped array;
• and
• controller means for controlling a phase and amplitude of feeds to each of said radiating elements, each of said radiating elements comprising:
• four metalized radiating elements arranged in a foursquare pattern, each of said four metalized radiating elements having at least two perpendicular sides;
• and
• at least one pair of feed points, connected to opposing ones of said four metalized radiating elements.
