Patent number: 7196666Abstract: A surface micromachined electromagnetically radiating antenna includes a coplanar waveguide on a ground plane coated substrate having a conductor path. The conductor path is coupled to a monopole conductor, which has a generally-cylindrical backbone erected vertically from the substrate and a metal layer deposited on the backbone at a predetermined thickness. The antenna may be fabricated by depositing an epoxy on the ground plane coated substrate to a predetermined depth and according to a pattern. The epoxy is exposed to an ultraviolet source that develops one or more columns according to the pattern. A seed layer of metal may be formed on the developed column. A conductive metal is electrodeposited over the column surface to produce the monopole antenna. Other antenna may be created by adding monopoles and/or conductive metal patches and/or strips that are positioned atop the monopoles and elevated from the substrate.Type: GrantFiled: June 6, 2005Date of Patent: March 27, 2007Assignee: Georgia Tech Research CorporationInventors: Mark G. Allen, Yong-Kyu Yoon, Jin-Woo Park, Yeun-Ho Joung, Florent Cros, Ioannis Papapolymerou, Emmanouil Tentzeris, Bo Pan

Patent number: 5821836Abstract: A high frequency micromachined filter assembly comprises at least one microresonator having at least one metal-lined resonance chamber and at least two openings. Input means couples an electromagnetic input signal to the resonance chamber through a first one of the openings. The output signal is coupled to output means from the resonance chamber through a second one of the openings. Dielectric material is arranged between the input means and the resonance chamber to maintain the resonator and the input means separated from one another. Dielectric material is arranged between the output means and the resonance chamber to maintain the resonator and the output means separated from one another.Type: GrantFiled: May 23, 1997Date of Patent: October 13, 1998Assignee: The Regents of the University of MichiganInventors: Linda P.
