Patent ID: 6914576

Claim:
A multi-resonant double-sided HTS magnetic dipole micro-antenna, comprising: a first YBCO thin-film is patterned into a first curvilinear shape to provide a first means for YBCO radiation on a top surface of an LAO substrate; a second YBCO thin-film is patterned in a second curvilinear shape to provide a second means for YBCO radiation on a bottom surface of said LAO substrate; said first YBCO radiating means generating a first magnetic flux; said second YBCO radiation means generating a second magnetic flux; said first YBCO radiation means and said second YBCO radiation means generating an inductive coupling by a magnetic dipole moment; said first YBCO radiating means being configured so that at any one of a plurality half-cycles a first current flow is in phase with a second current flow in said second YBCO radiating means; said first curvilinear shape and said second curvilinear shape each generate a circular polarization radiation pattern; a discontinuity between said first YBCO radiation means and said second YBCO radiation means causes a plurality of multi-resonant properties; said first YBCO radiation means, said second YBCO radiation means and said LAO substrate provide a decreased surface impedance; and said inductive coupling, said first current flow and said second current flow being in phase, said decreased surface impedance, said circular polarization radiation pattern and said plurality of multi-resonant properties permit a reduced antenna size with an increased antenna efficiency.
