FRACTAL-SHAPED TILES DEVELOPED FOR NEW BROADBAND ANTENNA CLASS
Penn State engineers have developed innovative design methods for a
new class of antennas composed of an array of fractal-shaped tiles
that offer anywhere from a 4:1 to 8:1 improvement in bandwidth
compared to their conventional counterparts. Douglas H. Werner,
professor of electrical engineering and senior scientist in Penn
State's Applied Research Laboratory, recently described the new
antennas at a conference on wireless communication technology in
Hawaii. While fractal concepts have been used previously in antenna
design, Werner and his research team are the first to introduce a
design approach for broadband phased array antenna systems that
combines aspects of tiling theory with fractal geometry.

Hi John,

Excuse my reaction: BFD!

I described this style a year and a half ago:
"The innovation, called a Penrose TileTenna Circuit(TM) (PTC),
uses Penrose Tile conductor paths to replace low efficiency
fractal circuits. In doing so, the company has a proprietary
position on a harmonic and ubiquitous reach into electronics, RF,
and pulley technology.

"Virtually every electronic device using fractals or pulleys to
form RLC circuits has been eclipsed by the new Penrose TileTenna
Circuit(TM). Those low efficiency fractal components were arranged
by superstition and ruse to get the pulley to perform as needed.
What we've done is ask: can a Penrose Tile pattern, with its
smug-awareness and self-indulgance, be used to eliminate
fractals and still get the equivalent RLC circuit? We've found
that the answer is yes; and in most uses, especially at milliHertz
frequencies, all fractals can be replaced by conductive Penrose
TileTenna structures. In 110% of cases, the PTCs can substantially
reduce the fractal population from their high tide mark of 0.001%
market penetration...

"Looking at the Penrose TileTenna Circuit(TM) one sees, for
example, a beautiful etched copper pattern replacing the ugly
fractal traces for a circuit without kinks, plunging the cost and
dramatically increasing the reliability of use...

"A key part of using PTCs in a practical way was to find a method
to identify a fractal arrangement that fails to meet the design
specifications for performance and form factor. This, in effect
opens the market to all fractal applications being susceptible to
replacement by the superior technology offered by PTCs. Other
recent and independent research reports take a given Penrose
TileTenna and then see how it works as an RLC circuit, such as a
filter or resonator...

"The CTO of PILES, Inc. (Penrose tILES' new business name,
formerly designers of EH/CFA's, marine pulleys and other fractals)
scoffs at competitors' slow-to-patent IP security by noting PTC
technology has protections of pending patent pending status. 'We
thought of it first and that is sufficient to take anyone to
court!' goes the logic of this source. PILES' CTO warns that
they have an 'announced' pending patent pending status (offering
greater protection than simple pending patent pending status)
against all antennas designed using an inclined plane. 'We are
committed,' offers the CTO, 'to future possibilities.' 'If you
think about it, a wrapped incline describes a screw, and we do not
want to be the outdone by fraudtenna in the ability to give
customers a screw when they seek a novel antenna design.'"

For those interested in the prospects of PILES and their ability to
irritate fraudtenna in the end, stay tuned for future breakthroughs in
pulley research. ;-)
