Re: NEC-LIST: Stub loading of antennas

At Virginia Tech, we have performed considerable research on stub loaded
helix antennas. It occupies only about 25% of the volume of a conventional
axial mode helix antenna, but still has considerable
bandwidth. See: http://antenna.ece.vt.edu/product/SLH.pdf.

One form of the SLH antenna is now a commercial product for 2.4 GHz
WLAN. See: http://www.frccorp.com/
