Embodiment Construction

[0017] In Fig. 1 a first embodiment 100 of an adjustable delay line according to the invention is shown in top view. The delay line 100 comprises a first conductor 110 having a first main direction of extension, indicated by arrow A in FIG. 1 . In addition to the first conductor 110, the delay line 100 also comprises a second conductor 120 having a second main direction of extension, indicated by arrow B in FIG. 1 .

[0018] Turning now to FIG. 2 , a cross-section of the arrangement 100 from FIG. 1 along line II-II in FIG. 1 is shown. It can be seen in Fig. 2 that the first and second conductors 110, 120 are arranged on top of a layer 130 of ferroelectric material having a high permittivity. Some examples of such materials are BaTiO 3 , SrTiO 3 and Ba, Sr and TiO 3 various compounds, usually expressed as Ba x Sr (1-x) TiO 3 or Na, K and NO 3 compounds, usually expressed as Na x K (1-x) NO 3 .

[0019] Underneath the layer 130 of ferroelectric material is disposed a...

Abstract

A tunable electromagnetic delay line, comprising a first conductor with a first main direction of extension, said first conductor being arranged on top of a non-conducting substrate, characterized in that the delay line additionally comprises a layer of a ferroelectric material with first and second main surfaces, which layer separates the first conductor and the substrate, and in that the delay line also comprises a second conductor with a second main direction of extension, with the first and second main directions of extensions essentially coinciding with each other, and with the first and second conductors being each other's mirror image with respect to an imagined line in the center of the delay line along said first and second main directions of extension, said tuning being accomplished by applying a voltage between said first and second conductors.

Description

technical field [0001] The present invention relates to a tunable electromagnetic delay line comprising a first conductor having a first principal direction of extension, said first conductor being located on top of a non-conductive substrate. Background technique [0002] Extension cords are a common component in many modern electrical systems (usually microwave systems). Radar systems, amplifiers and oscillators may be mentioned as examples in the technical field using delay lines. [0003] Most of the technologies used in delay lines result in bulky components that are often not cost-effective and difficult to integrate with standard semiconductor technologies. Also, it is highly desirable that the delay line be adjustable, ie have a delay time that can be changed. Also, most modern adjustable delay lines are quite power hungry, which is usually a disadvantage. Contents of the invention [0004] Therefore, as mentioned above, there is a need for an adjustable delay l...
