A phase shifter includes a substrate, a first electrode positioned on a surface of the substrate, a tunable dielectric layer positioned on a surface of the electrode, a microstrip positioned on a surface of the tunable dielectric layer opposite the substrate, an input for coupling a radio frequency signal to the microstrip, an output for receiving the radio frequency signal from the microstrip, and a connection for applying a control voltage to the electrode. In an alternative embodiment, a second electrode can be positioned on the surface of the substrate and separated from the first electrode to form a gap positioned under the microstrip.

La présente invention concerne un déphaseur à micro-ruban comprenant un substrat, une première électrode placée sur une surface du substrat, une couche diélectrique accordable placée sur une surface de l'électrode, un micro-ruban placé sur une surface de la couche diélectrique réglable opposée au substrat, une entrée pour coupler un signal radiofréquence au micro-ruban, une sortie pour recevoir le signal radiofréquence provenant du micro-ruban, et une connexion pour appliquer une tension de régulation à l'électrode. Dans une variante, on peut placer une seconde électrode sur la surface du substrat, à distance de la première électrode, pour former un espace sous le micro-ruban.
