Embodiment Construction

[0052] The following embodiments are exemplary. Although this specification may refer to "a", "an" or "some" embodiment(s) in several places, this does not necessarily mean that each such reference is for the same embodiment(s) , Or features only apply to a single embodiment. Individual features of different embodiments may also be combined to provide other embodiments.

[0053] Currently, it is possible to use a digital control switch that sets the filter and "pipe" to be used to select the frequency band using one antenna. That is a fixed method and there is no fine-tuning or compensation for component changes. In the case of fewer frequencies and system bands, this may be no problem, but an increasing number of bands / systems can cause this method to fail. On the other hand, separate circuits and logic can be used to handle antenna matching fine-tuning and component change compensation. These front-end tuners can cause complexity (cost and size issues) and result in fairly ...

Abstract

There are disclosed various apparatuses and methods for tuning a resonance frequency. In some embodiments there is provided an apparatus (200) comprising at least one input electrode (202, 204) for receiving radio frequency signals; a graphene foil (210) for converting at least part of the radio frequency signals into mechanical energy; at least one dielectric support element (212) to support the graphene foil (210) and to space apart the at least one input electrode (202, 204) and the graphene foil (210). The graphene foil (210) has piezoelectric properties. In some embodiments there is provided a method comprising receiving radio frequency signals by at least one input electrode (202, 204) of an apparatus (200); providing a bias voltage to the apparatus (200) for tuning the resonance frequency of the apparatus (200); and converting at least part of the radio frequency signals into mechanical energy by a graphene foil (210) having piezoelectric properties.

Description

Technical field [0001] The invention relates to a device for tuning the resonance frequency of a resonator. The invention also relates to a method for tuning the resonance frequency of a resonator. Background technique [0002] This section is intended to provide the background and context for the invention stated in the claims. The description here may include ideas that can be pursued, but not necessarily ideas that have been previously conceived or pursued. Therefore, unless otherwise indicated herein, the content described in this section is not related to the prior art of the specification and claims in this application, and is not admitted to be prior art by being included in this section. [0003] With the use of many radio communication schemes (standard and non-standard), the modern radio communication environment is very diverse. The user equipment may be equipped with the ability to communicate through a variety of different radio communication schemes, such as GSM, G...
