Claim 6:
7. An antenna comprising:
a first metal layer disposed on a first surface of a first dielectric substrate;
a second metal layer disposed between a second surface of the first dielectric substrate and a first surface of a second dielectric substrate, wherein a second surface of the second dielectric substrate is opposite the first surface of the second dielectric substrate;
wherein the first dielectric substrate includes one or more first cavities, each of the one or more first cavities extending from the second surface of the first dielectric substrate to a first selected depth, through the first dielectric substrate, that does not reach the first surface of the first dielectric substrate;
wherein the second dielectric substrate includes one or more second cavities, each of the one or more second cavities extending from the second surface of the second dielectric substrate, that does not reach the first surface of the second dielectric substrate; and
where (1) positions of the one or more first or second cavities are configured to be modified, or (2) a sizes of the one or more first or second cavities are configured to be modified.
