... Hope for what? Magic? The tradeoffs inherent in electrically small antennas are well known, and each design requires intelligent application of that knowledge to come up with an antenna that's acceptable in size, form factor, and performance for that particular use. Many, many antennas now being designed and ones in common use are electrically small -- the ones in your car's remote control key fob, your Bluetooth USB dongle or cell phone earpiece, and embedded in RFID tags are just a very few examples. With the increasing use of wireless devices, the need for electrically small antennas has grown rapidly, and there are a number of good texts devoted to that specific topic. These texts contain a good treatment of the tradeoffs involved and useful ideas for designs using currently available technology and materials, but no new fundamental theory. Advancements in the art will continue to come with intelligent and clever application of established theory by people who understand the theory and how to apply it, not from tinkerers who lack this knowledge and conjure their miracles by vague hand-waving and bad measurement. Roy Lewallen, W7EL Ahh, the "magic man" himself is here ... the guy who write a simplistic interface to feed a text file to the real NEC engine ... My gawd man, carry on, we await you wisdom ... smiling-out-the-one-side-of-ones'-face With all DUE respect, JS |
