Antenna bump for later.

Soon our phones will be so small we will need a special device to find them.

Accelerating electrons? Don’t they move at the speed of light? What the heck?!

Interesting. Spent my career building antennas and systemes, usually rather large. Hated requirements for small antennas.

Makers of Chip Antennas will be happy to know this. http://www.vishay.com/chip-antenna/

To me, the first sentence does not sound correct...

"What hasn't been known is how the dielectric medium results in emission of electromagnetic waves. This mystery has puzzled scientists and engineers for more than 60 years."

The dielectric medium is considered a passive component and requires energy input to emit electrons.

Otherwise I think I understand the basic concept. I can only imagine its application in transmission of a radio signal. The reception is still going to be limited by the capture area of physical antenna.

That would be cool if they could uncouple the wavelength of the signal from the antenna size I’m excluding 1/8 and 1/4, etc. wavelengths.

I just wish some genius could make a Garage Door Opener antenna that actually worked so I don’t have to pull the nose of my car right up next to the door.

>> asymmetric excitation <<

Hmm. Reminds me of a certain old girlfriend!

Note, in the picture, everything in the green area-- the gold SMA connector, the microstrip trace, the tiny coupling capacitors-- is normal RF stuff. Nothing new. The antenna is on the exposed chip to the right.

As a 30-year veteran RF circuit design engineer, I'm highly skeptical of this article. But they might be on to something. Time will tell.
