An Antenna on a Button

February 24, 2012

Reading physorg.com, I came across this story about miniaturizing antennas for smaller wireless devices. Apparently, the size of the antenna often limits the size of the wireless device – so let’s make those antennas smaller. The article is about a group from the University of Michigan who achieves this by using a hemispherical substrate with a spiraling antenna taking advantage of the volume that the hemisphere provides.

RF Modeling

Not having seen an example of this in COMSOL’s model suite, I went to our RF guy, Jiyoun, and asked him if it could be built. Jiyoun’s been doing heaps of RF modeling lately, but I hadn’t seen an antenna on a button pass my way.

COMSOL Model of Hemisphere Antenna

It seems as though Jiyoun had the same problem as the manufacturers; it’s pretty difficult to create that spirally-pattern on the hemisphere. Yet, two hours later he had produced a model. Good stuff Jiyoun!
