DARTS Gallery

Last Updated: April 18, 1999

Welcome to the Gallery! On display: anything that's currently "happening" with DARTS.  Current events info and pictures are posted here before passing into History. Sometimes, previews of coming events are here.   You get the idea.

Please click on the small photos to see the large, bandwidth-eating full-size version. Lynx users, note that the alternate to the filename is the full URL to the large version.  To get the codecs required for AVI files, see the History section.



NEW ARRAY ANTENNA

The array was created out of 7x1 element resonant-series-fed sections. The aperture distribution is a cosine-squared-on-a-pedestal, with a taper of 6 dB. I used Robert Sainati's "CAD of Microstrip Antennas" DOS programs to design the array, then simulated it with the (expensive) planar EM simulator Ensemble, which my company is evaluating.
