1. An antenna comprising: a structure configured to receive or transmit electromagnetic waves or both; wherein the structure is configured to electrically connect to a circuit, wherein at least one portion of the structure comprises a bulk solidifying amorphous alloy. 2. The antenna of claim 1, wherein the circuit is a circuit of a telecommunication device. 3. The antenna of claim 1, wherein the antenna further comprises at least one connecting element, electrically connected to the structure and configured to connect the structure to the circuit. 4. The antenna of claim 1, wherein the structure comprises a plate, a connected pole, a wire or a strip. 5. The antenna of claim 1, wherein the structure is serpentine or sinuous in shape. 6. The antenna of claim 1, wherein the bulk solidifying amorphous alloy comprises ductile crystalline phases precipitate. 7. The antenna of claim 1, wherein the bulk solidifying amorphous alloy has a featureless microstructure. 8. The antenna of claim 1, wherein the bulk solidifying amorphous alloy has an isotropic microstructure. 9. The antenna of claim 1, wherein the bulk solidifying amorphous alloy substantially lacks an oriented crystalline grain structure. 10. The antenna of claim 1, wherein the bulk solidifying amorphous alloy substantially lacks an elongated crystalline grain structure. 11. The antenna of claim 1, further comprising a coating of copper, nickel, gold or a combination thereof, on a surface of the structure. 12. The antenna of claim 1, wherein the bulk solidifying amorphous alloy has an elastic strain limit of 1.5% or more. 13. The antenna of claim 1, wherein the structure is entirely made of bulk solidifying amorphous alloy. 14. The antenna of claim 1, wherein the bulk solidifying amorphous alloy has a hardness of 4.5 GPa or higher. 15. The antenna of claim 1, wherein the bulk solidifying amorphous alloy has a yield strength of 200 ksi or more. 16. The antenna of claim 1, wherein the bulk solidifying amorphous alloy has an electrical resistivity of 400 micro ohm-cm or less. 17. The antenna of claim 1, wherein the bulk solidifying amorphous alloy is described by the following molecular formula: (Zr, Ti)a(Ni, Cu, Fe)b(Be, Al, Si, B)c, wherein “a” is in the range of from 30 to 75, “b” is in the range of from 5 to 60, and “c” in the range of from 0 to 50 in atomic percentages. 18. The antenna of claim 1, wherein the bulk solidifying amorphous alloy is described by the following molecular formula: (Zr, Ti)a(Ni, Cu)b(Be)c, wherein “a” is in the range of from 40 to 75, “b” is in the range of from 5 to 50, and “c” in the range of from 5 to 50 in atomic percentages. 19. A communication device comprising the antenna of claim 1, a circuit configured to amplify and decode electrical signals converted from electromagnetic waves received by the antenna; wherein the antenna is electrically connected to the circuit. 20. An antenna comprising a receiving and/or transmitting structure, wherein at least one portion of the structure comprises a ferrous-based bulk solidifying amorphous alloy having a yield strengths up to 500 ksi or higher and a hardness value of 1000 Vickers and higher.
