A two-dimensional (2-D) beam steerable phased array antenna is presented comprising a continuously electronically steerable material including a tunable material or a variable dielectric material, preferred a liquid crystal material. A compact antenna architecture including a patch antenna array, tunable phase shifters, a feed network and a bias network is proposed. Similar to the LC display, the proposed antenna is fabricated by using automated manufacturing techniques and therefore the fabrication costs are reduced considerably.

Electronically steerable planar phase array antenna

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.

The invention relates to a device for determining at least one parameter of at least one medium, said medium being introducible into at least one measuring path. An electric and/or electromagnetic field can be partially coupled into or out of the medium by passing at least one electric and/or electromagnetic signal into the measuring path. The measuring path comprises at least one line arrangement having at least two elementary cells arranged along the measuring path, said elementary cells comprising at least one electric path from at least one input to at least one output and comprising at least one respective capacitative element. The electrical properties of the capacitative element can by be modified by the medium. The electric and/or the electromagnetic signal can be applied to the input of a first elementary cell and the output of the first elementary cell can be connected to the input of a second elementary cell. The capacitative element of the respective elementary cell is arranged in the electric path of the first and second elementary cell. At least one inductive element connects the first elementary cell and the second elementary cell to a ground. The invention also relates to a method for determining a parameter of a medium.
