Dielectricloaded
Dielectricloaded, often written as dielectric-loaded, refers to devices in which a dielectric material partially or fully fills the interior of a guiding structure, such as a waveguide or resonator, to modify electromagnetic modes. The dielectric changes the effective permittivity, phase velocity, and field confinement, enabling size reduction and tailored dispersion for microwave and millimeter-wave applications.
In dielectric-loaded waveguides, a dielectric insert increases the effective permittivity, slowing microwaves and enabling compact circuits
Applications span microwave and millimeter-wave systems, including compact filters, resonators, and slow-wave structures. Dielectric-loaded antennas use
Advantages of dielectricloaded designs include potential size reduction, improved quality factors, and opportunities for integration with
