    Abstract: 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.

    Abstract: A self-similar multiband reconfigurable antenna includes a planar antenna structure formed on a surface of a substrate, the antenna structure including symmetrically opposed self-similar geometry antenna arms defining a self-similar or Sierpinski gasket configuration for each arm of the antenna. MEMS type switches are provided for operatively connecting adjacent antenna patches on each arm of the antenna configuration, and a voltage source is provided for selectively actuating the switches. Selective actuation of the switches enables up to four different antenna configurations each having a different resonant frequency, and wherein each resonant frequency demonstrates a similar radiation pattern.

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.
