6127977 Microstrip patch antenna with fractal structure October 3, 2000
A microstrip patch antenna having reduced size is implementing by providing a substrate having on one surface a conductive fractal pattern, and having on the other surface a conductive pattern that may (but need not) also be a fractal pattern. The fractal pattern is of order N.gtoreq.1,
6104349 Tuning fractal antennas and fractal resonators August 15, 2000
A first fractal antenna of iteration N.gtoreq.2 in free space exhibits characteristics including at least one resonant frequency and bandwidth. Spacing-apart the first fractal conductive element from a conductive element by a distance .DELTA., non-planarly or otherwise, preferably .l
5862269 Apparatus and method for rapidly convergent parallel processed deconvolution January 19, 1999
An image processing system and method which may be used for standalone deconvolution or, alternatively, may be employed as a staring point for very rapid convergence with subsequent use of prior art deconvolution methods. Processing speed is improved because the sequential requirement
