New antenna technology???
Anyone know anything about the "technology" in the article below?
http://www.uri.edu/news/releases/?id=2659 Chuck...K1KW Article text below --------------------------------------------- Department of Communications/News Bureau 22 Davis Hall, 10 Lippitt Road, Kingston, RI 02881 Phone: 401-874-2116 Fax: 401-874-7872 ---------------------------------------------------------------------------- ---- URI physics employee invents new antenna technology Media Contact: Jan Wenzel, 401-874-2116 KINGSTON, R.I. -- June 2, 2004 -- Rob Vincent, an employee in the University of Rhode Island's Physics Department, proves the adage that necessity is the mother of invention. An amateur radio operator since he was 14, Vincent has always lived in houses situated on small lots. Because he couldn't erect a large antenna on a confined property, he has been continually challenged over the years to find a way to get better reception. "I was always tinkering in the basement. Thank goodness, my parents were tolerant. I can still remember my poor father driving up our driveway after a hard day's work to see wires wrapped around the house," Vincent recalls. "The Holy Grail of antenna technology is to create a small antenna with high efficiency and wide bandwidth," explains Vincent. "According to current theory, you have to give up one of the three-size, efficiency, or bandwidth-to achieve any one of the other two." After decades of experimentation, combined with a 30-year engineering career and Yankee ingenuity, Vincent has invented a revolutionary antenna technology. The distributed loaded monopole antennas are smaller, produce high efficiency, and retain good to excellent bandwidth. And they have multiple applications. With this technology it will be possible to double, at minimum, the range of walkie-talkies used by police, fire, and other municipal personnel. Naval ships, baby monitors, and portable antennas for military use are other applications. An antenna could be mounted on a chip in a cell phone and be applied to wireless local area networks. Another application deals with radio frequency identification, which is expected someday to replace the barcode system. "It could even make the Dick Tracy wrist radio with all the features, such as Internet access, a possibility," Vincent says. The inventor pursued his quest to build a better antenna in earnest eight years ago when he and his significant other moved into a house situated on a 50-foot by 100-foot lot in Warwick. There was nothing on the commercial market that could fit the lot that would provide the performance Vincent needed to be heard in distant lands and that would be acceptable to his neighbors. All the small antennas being sold were inefficient and lacked bandwidth, which resulted in low performance and high frustration. Vincent looked at the techniques that were currently used to reduce antenna size and realized something was missing in the way everyone was approaching the problem. He began to model various combinations into a computer program called MathCad. His first attempt produced a 21 MHz band antenna that was 18 inches high. Normally, antennas for this band are 12 to 24 feet high. Vincent installed the antenna in his back yard. The legal limit that amateurs can operate is 1,000 watts with the norm being 100 watts. The amateur radio operator experimented with 5 to 10 watts. He reached a station in Chile and made contacts in various European countries. Meanwhile he kept adding power until it reached 100 watts. That's when things suddenly went bad. Walking outside in the backyard, he understood why. The antenna had melted. After examining the molten matter, Vincent wasn't discouraged. This was only a small model and not designed to handle much power. The part of the antenna that failed proved to be the key to the design. After analyzing the failure, Vincent realized that he was able to transform a lot of current along the antenna with even relatively low power. "Antennas radiate by setting up large amounts of current flow through various parts of their structure," he says. "The larger the current the more radiation and the better the output of the antenna." Vincent went back to the drawing board and continued to improve the technology. Relying on his nearly 30 years at Raytheon Co. and at KVH Industries in Middletown R.I which provided him with a diversified background in electronics and electronic systems, Vincent overcame a myriad of problems and succeeded. He established three test sites for various prototypes. Antennas were placed in Westport, Mass. in a salt marsh, the best ground for transmission and reception. Another set of antennas were placed on rocky ground in Cumberland, R.I., the worst kind of site, and at a Warwick site which is in between the two. The antennas, which resemble flagpoles, worked well at all locations. Tests confirmed that Vincent has created antennas at one third to one ninth of their full size counterparts. Normally smaller antennas are only 8 to 15 percent efficient. Vincent's antennas achieved 80 to 100 percent efficiency as compared to the larger antennas. A patent is pending on Vincent's technology. The inventor has made the University of Rhode Island and its Physics Department partners that will benefit from any revenue his invention earns. "The University and its Physics Department has been very supportive and given me time and space to work on this project," says Vincent who was recently presented the 2004 Outstanding Intellectual Property Award by URI's Research Office. "I couldn' t have done this without the University's support. It's only fair that it share in the profits." |

http://www.uri.edu/news/releases/?id=2659 No, they do not explain the "new" technology. This is the way the CFA and EH got started. Vincent has created a revolutionary antenna technology using Yankee ingenuity. Sorry, being from the South, I don't care for Yankees. More details are needed, but the antenna will be about like the CFA and EH. Build it (when you find out how). It will not work, just like the CFA and EH. 73 Gary N4AST |

An antenna that melts with 100W of RF going to it seems to be at odds with its claim of high efficiency. Tam/WB2TT |
Oh come on, he said it's revolutionary! You are being way too judgemental.
The melting probably had nothing to do with losses. I mean, it could have burst into flames due to corona igniting the revolutionary materials it was made of, and that's what melted it. Yeah, that's the ticket. tom K0TAR Tam/WB2TT wrote: An antenna that melts with 100W of RF going to it seems to be at odds with its claim of high efficiency. Tam/WB2TT |

Then again, perhaps we're still thinking too far inside the box. What if this antenna is meant to radiate HEAT ? Hmmm doesn't do that all that well either - I know cover the thing in fins like a '60s car...:-) -- Humbug |

This post below makes me think of the remarkable miniature "plastic apple" antenna. The requirement that the apple must be located far away from the radio and conected to it with a copper wire, is important. "Chuck...K1KW" wrote in message news:0wNvc.39192$3x.31853@attbi_s54...

Links: http://www.tfcbooks.com/special/lf/teslavert.htm Werner has the device located indoors at his home and is enjoying many QSOs on 160. http://www.antennex.com/Stones/st0503/st0503.htm Of particular interest was one variation of the design, for 160M, that used a flat coil and a spherical radiator at the top. As Werner studied the design, he started to think about the role of spherical shapes in general Physics and noted that virtually all real shapes, and shape models found in the universe are spheres or derivatives! So, Werner concluded why not use spheres for experiments with capacitive radiators? And why not see what could be learned about the superposition of fields, by using these shapes? Here's a cite to a fractal sphere antenna: Facchine, M.J.; Werner, D.H.; "Electromagnetic scattering from fractal spheres", Antennas and Propagation Society International Symposium, 2002.
