Abstract

A broad band antenna including: a body formed of a material having a relative permittivity of 2 to 20, a relative permeability of 1 to 10, and a magnetic loss tangent of 0.001 to 0.2, at a usable frequency; and at least one radiator disposed on the body. The material forming the body may be a composite material formed of a polymer resin mixed with a magnetic powder. The composite material may contain the magnetic powder by 90 wt % with respect to a total weight.

Claims

1. A broad band antenna comprising:

a body formed of a material having a relative permittivity of 2 to 20, a relative permeability of 1 to 10, and a magnetic loss tangent of 0.001 to 0.2, at a usable frequency; and

at least one radiator disposed on the body.

2. The broad band antenna of claim 1, wherein the material forming the body is a composite material formed of a polymer resin mixed with a magnetic powder.

3. The broad band antenna of claim 2, wherein the composite material contains the magnetic powder by 90 wt % with respect to a total weight.

4. The broad band antenna of claim 2, wherein the magnetic powder comprises a magnetic substance having at least one element selected from Fe, Ni, Co, Mn, Mg, Ba, Sr and Zn.

5. The broad band antenna of claim 4, wherein the magnetic powder comprises at least one selected from carbonyl iron, a Ba ferrite, a NiZn ferrite and a MnZn ferrite.

6. The broad band antenna of claim 5, wherein the magnetic powder is the carbonyl iron and the composite material contains the magnetic powder by 45 to 85 wt % with respect to a total weight.

7. The broad band antenna of claim 5, wherein the magnetic powder is the NiZn ferrite and the composite material contains the magnetic powder by 45 to 90 wt % with respect to a total weight.

8. The broad band antenna of claim 5, wherein the magnetic powder is the Ba ferrite and the composite material contains the magnetic powder by 50 to 87.5 wt % with respect to a total weight.
