Abstract

An electrical component provides a ceramic element located on or in a dielectric substrate between and in contact with a pair of electrical conductors, wherein the ceramic element includes one or more metal oxides having fluctuations in metal-oxide compositional uniformity less than or equal to 1.5 mol % throughout the ceramic element. A method of fabricating an electrical component, provides or forming a ceramic element between and in contact with a pair of electrical conductors on a substrate including depositing a mixture of metalorganic precursors and causing simultaneous decomposition of the metal oxide precursors to form the ceramic element including one or more metal oxides.

First claim

What is claimed is:

1. An antenna, comprising:
a folded antenna element having a maximum dimension D; and
a meta-material dielectric body embedding said folded antenna element a distance S from an exterior surface of said meta-material dielectric body;
wherein said meta-material dielectric body comprises a dielectric host having a relative permittivity ∈ R ≦10 and one or more dielectric inclusions having relative permittivity ∈ R >10;
wherein said distance S is greater than the protrusion length d of the folded antenna element's reactive near-field region, and
wherein said reactive near-field protrusion length d is defined as d=0.62 √(D 3 /λ), and λ is the wavelength of an electromagnetic excitation emitted or received by said folded antenna element.

2. The antenna of claim 1 , wherein the dielectric host is an organic dielectric.

3. The antenna of claim 2 , wherein said organic dielectric includes FR4, Rogers Duroid or PFTE Teflon dielectric.

4. The antenna of claim 2 , wherein said organic dielectric host has a loss tangent tan δ≦10 −3 .

5. The antenna of claim 2 , wherein the dielectric host is an inorganic dielectric.

6. The antenna of claim 5 , wherein said inorganic dielectric host is a silica or alumina dielectric.

7. The antenna of claim 5 , wherein said inorganic dielectric host has a loss tangent tan δ≦10 −3 .

8. The antenna of claim 5 , wherein said inorganic dielectric host has a value for relative permittivity ∈ R that is stable over operating temperatures between −150° C. and +250° C.

9. The antenna of claim 1 , wherein the inclusions are spatially separate from all elements of the antenna.

10. An antenna, comprising:
a folded antenna element having a maximum dimension D; and
a meta-material dielectric body embedding said folded antenna element a distance S from a dielectric inclusion contained within said meta-material dielectric body;
wherein said meta-material dielectric body comprises a dielectric host having a relative permittivity ∈ R ≦10 and one or more dielectric inclusions having relative permittivity ∈ R >10;
wherein said distance S is greater than the protrusion length d of the folded antenna element's reactive near-field region, and
wherein said reactive near-field protrusion length d is defined as d=0.62√(D 3 /λ), and λ is the wavelength of an electromagnetic excitation emitted or received by said folded antenna element.
