Claim 18:
19. A phased array antenna comprising:
a plurality of antenna elements, each antenna element comprising:
an input planar resonator element having an input port, the input planar resonator element being a planar metallic patch resonator;
a supplementary planar resonator element, the supplementary planar resonator element being a planar metallic patch resonator;
a planar radiator element, the planar radiator element being a planar metallic patch radiator;
an input resonator ground element disposed between the input planar resonator element and the supplementary planar resonator element, the input planar resonator element electrically coupled to the supplementary planar resonator element through the first planar input resonator ground element; and
a planar ground element disposed between the planar radiator element and the input planar resonator element, the input planar resonator element electrically coupled to the planar radiator element through the planar ground element,
each antenna element configured to radiate, when an electromagnetic signal is applied to the input port, electromagnetic energy from the planar radiator element in accordance with a filter transfer function from the input port through the planar radiator element to free space,
the filter transfer function determined at least in part by a distance between the planar radiator element and the input planar resonator element.
