- *Abstract
-
The performance of radio antennas can be degraded from interference caused by thermal radiation as well as signals traveling along the ground and reflected by the ground.
To minimize these sources of interference, researchers at UC Berkeley have developed design enhancements for radio antennas. These refinements minimize thermal background noise as well as low radio frequency interference, and they don?t intercept radiation along the symmetry axis of the antenna, or any rays that reach the feed (detector).
