Abstract
A resonance cavity comprising a first layer of dielectric material having a first dielectric constant and a first thickness, a second layer of dielectric material having a second dielectric constant different from the first dielectric constant and a second thickness, a metal patch arranged between the first and the second layer of dielectric material, and an electromagnetically shielded enclosure having at least one aperture, the electromagnetically shielded enclosure arranged to enclose part of the first and second layers of dielectric material and the metal patch.

A resonance cavity comprising:
- a first layer of dielectric material associated with a first dielectric constant and a first thickness;
- a second layer of dielectric material associated with a second dielectric constant different from the first dielectric constant and a second thickness;
- a metal patch having a shape arranged between the first and the second layer of dielectric material;
- and
- an electromagnetically shielded enclosure having at least one aperture, the electromagnetically shielded enclosure arranged to enclose part of the first and second layers of dielectric material and the metal patch, whereby the shape of the metal patch affects a resonance frequency of the resonance cavity.
A method for tuning a resonance frequency of a resonance cavity, comprising:
- selecting a first dielectric constant and a second dielectric constant different from the first dielectric constant;
- selecting a first and a second dielectric material thickness;
- selecting a metal patch shape;
- and
- configuring a first layer of dielectric material having the first dielectric constant and the first thickness, a second layer of dielectric material having the second dielectric constant and the second thickness, a metal patch interspersed between the first and the second dielectric layer having the selected metal patch shape, and an electromagnetically shielded enclosure having at least one aperture, the electromagnetically shielded enclosure arranged to enclose part of the first and second layers of dielectric material and the metal patch.
