Claim 0:
1. 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;
an intermediate planar resonator element, the intermediate planar resonator element being a planar metallic patch resonator;
a planar radiator element, the planar radiator element being a planar metallic patch radiator;
a first planar ground element disposed between the input planar resonator element and the intermediate planar resonator element, the input planar resonator element electrically coupled to the intermediate planar resonator element through the first planar ground element; and
a second planar ground element disposed between the planar radiator element and the intermediate planar resonator element, the intermediate planar resonator element electrically coupled to the planar radiator element through the second 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 intermediate planar resonator element.
