摘要： A phase shift device includes a planar transmission line that is formed by a signal electrode and a ground electrode which are separated by a dielectric substance, whereby the signal electrode of the planar transmission line is divided into several pieces and includes overlapping areas of adjacent pieces that are filled with a tunable liquid crystal material, thereby forming a dielectric tunable component (varactor) with a metal-insulator-metal type capacitor. The several pieces of the signal electrode are arranged at two or more different distance levels with respect to the ground electrode. The tunable liquid crystal material is arranged as a continuous layer between several pieces of the signal electrode that are arranged at two different distance levels.

摘要： A system and method for an electronically scanned antenna is provided in which phase shifters are deposited en masse along with other electronically scanned antenna components on a wafer scale substrate using a thin film process. Alternative wafer scale sizes may be utilized to furnish a required antenna aperture area. Significant processing costs for radar and communication systems are saved utilizing the present invention as compared with contemporary discrete phase shifters that are individually mounted on an antenna. In an aspect, the phase shifter is made up of a base electrode, a barium strontanate titanate (BST) ferroelectric varactor and a top electrode. The BST ferroelectric material is a voltage variable dielectric, which generates a radiation phase. The radiation phase is regulated by a phase shifter control. The radiation phase generates an electromagnetic field about a radiating element and electromagnetic radio waves are radiated from the radiating element.

摘要： Provided are a distributed analog phase shifter and a method of manufacturing the same, which reduce a change in a characteristic impedance while changing a phase velocity with respect to an applied voltage. In the distributed analog phase shifter, a coplanar waveguide (CPW) is formed in a line form on a substrate. A plurality of ferroelectric capacitors is periodically loaded to the CPW. The ferroelectric capacitors include a ferroelectric film in a pattern form and defines the ferroelectric film affected by the applied voltage within an area of the ferroelectric capacitors. Accordingly, the change in the phase velocity with respect to the applied voltage is maintained without the change of the CPW characteristic and a return loss characteristic and a total insertion loss are improved since a total dielectric loss of the ferroelectric film is decreased.
