Abstract
Examples disclosed herein relate to methods and apparatuses for a radiating structure to radiate a transmission signal, where the radiating structure incorporates reactance control elements to change a reactance of transmission lines and/or radiating unit cell elements, and a resonant coupler to isolate the transmission signal from a reactance control signal to the reactance control elements. A reactance control signal, such as a bias voltage, controls the reactance of transmission lines of the transmission array structure and/or the radiating unit cell elements so as to change the phase of the transmission signal, thereby steering a beam of the transmission signal. The reactance control elements may be incorporated into a microstrip within the transmission lines.
