Claim 0:
1. An antenna system comprising:
a zig-zag antenna array including:
a conductive disk stack of conductive disks;
at least one crossed zig-zag antenna extending through the conductive disk stack of conductive disks, the at least one crossed zig-zag antenna including:
an element pair that includes a plurality of crossed zig-zag antenna segment pairs between the conductive disk stack of conductive disks, wherein a respective crossed zig-zag antenna segment pair extends between a respective lower conductive disk and a respective upper conductive disk; and

a control circuit coupled to the element pair to switch the crossed zig-zag antenna segment pairs to drive the crossed zig-zag antenna segment pairs to transmit or receive radio frequency (RF) waves with polarization states that include vertical, horizontal, elliptical, and circular polarization.
