An antenna element including a ring, and one or more feed probes extending from the ring, wherein the ring and feed probe(s) are formed from a unitary piece.

An antenna element including a ring;

• and a feed probe having a coupling section positioned proximate to the ring to enable the feed probe to electromagnetically couple with the ring, wherein the coupling section of the feed probe has an inner side which cannot be seen within an inner periphery of the ring when viewed in plan perpendicular to the ring.

A microstrip antenna including a ground plane;

• a radiating element spaced from the ground plane by an air gap;
• a feed probe having a coupling section positioned proximate to the ring to enable the feed probe to electromagnetically couple with the ring;
• and a dielectric spacer positioned between the radiating element and the feed probe.

A dual polarized antenna element including a ring;

• and two or more feed probes, each feed probe having a coupling section positioned proximate to the ring to enable the feed probe to electromagnetically couple with the ring.
