RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Spray WiFi Hot Spots on Everything

Spray Hot Spots on Everything - RF CafeLet me check the calendar. Nope, it's not April 1st. This item on Wired magazine's website reports a spray-on antenna product that, according to inventor Chamtech Enterprises, works near miracles on almost any antenna within its operational frequency (no details at this point). Tests have been conducted at 50 MHz (underwater communications) 100 MHz (aircraft VHF), 2 GHz (iPhone), and 2-5 GHz (microwave RFID tag). What is so magic about the spray? nCap Technology (antenna in a can - starts at 1:00 point in video)) - RF CafePer a recent press release, "Chamtech's patented nCap Technology is a breakthrough in antenna technology, replacing or enhancing traditional antennas to improve signal range, data rate, and battery life of devices relying upon antenna technology." This appears to be the patent application: Techniques for Conductive Particle Based Material Used for at Least One of Propagation, Emission and Absorption of Electromagnetic Radiation, 20120146855.
