Antennas: The Black Art Of Wireless
By Louis Frenzel, Communications/Test Editor

I have always been amazed by how much difference a good antenna makes in a wireless application. It became pretty clear to me at an early age as a ham radio operator that a good antenna is the difference between making a connection or not. But now, having stated the obvious let me say that designing a new antenna is just as much art as it is a science.

quick poll |
Last month, Richard Branson unveiled SpaceShipTwo. If you had a spare $200,000, would you sign up for a ride?


  • Sign me up! It would be a dream vacation.
  • Maybe, but I'd wait to see if the flights are really safe first.
  • No way. Space tourism is a waste of money.

Rev Up Your Interdisciplinary Design Skills


What happens when a microcontroller turns on a power FET, sending a current pulse to a motor coil that develops a magnetic field which turns the rotor shaft, advancing a timing belt that drives a pair of nip rolls suspended on bearings in a web-processing operation on a form, fill, and seal machine installed on a potato chip line at a Frito Lay plant in central California? And how can you be sure that the encoders, prox sensors, and other feedback devices you plan to use will accurately see and report every relevant motion, machine state, and process condition? And will the signals get through the networks fast enough, without being corrupted, giving the controllers time to execute their algorithms as intended?

It's a lot to think about, and it only scratches the surface of what many engineers grapple with today. If you happen to be one of them, then the place for you -- where you can find answers and meet others with similar concerns -- is Mechatronic-Design.com.

Backed by some of engineering's top information sources including Machine Design, Electronic Design, Motion System Design, and Power Electronics, Mechatronic-Design.comis the interdisciplinary engineer's desktop, toolbox, library, and lifeline in one easily accessible place.
