Method and apparatus for reactance control in a transmission line

A method for operating a radiating structure, the method comprising:

• transmitting, by a plurality of transmission lines, at least one transmission signal, wherein each of the transmission lines comprises a plurality of slots;
• changing, by at least one reactance control element controlled by at least one reactance control signal, a reactance of at least one of the transmission lines to change a phase of at least one of the transmission signal(s) within the at least one of the transmission lines;
• isolating, by at least one resonant coupler, the at least one transmission signal from the at least one reactance control signal;
• and
• radiating, by a plurality of unit cell elements, the at least one transmission signal, wherein the unit cell elements are mounted proximate the slots of the transmission lines such that the at least one transmission signal radiates from the transmission lines to the unit cell elements via the slots of the transmission lines.

A transmission array structure, the transmission array structure comprising:

• an array of transmission lines, wherein at least one of the transmission lines comprises:
• a first portion comprising:
• a dielectric layer;
• a first conductive layer on a first side of the dielectric layer;
• a reference conductive layer on a second side of the dielectric layer opposite the first side;
• and
• a first set of vias formed within the dielectric layer, conductively coupling the first conductive layer to the reference conductive layer, wherein the vias define the transmission lines;
• and
• a second portion comprising:
• a second reference conductive layer configured within the dielectric layer;
• and
• a second set of vias formed within the dielectric layer, conductively coupling the first conductive layer to the second reference conductive layer.
