Size vs. Performance: The UWB Antenna Dilemma
Typical consumer electronic devices sacrifice antenna performance in favor of smaller, more cosmetic form factors. A foot-diameter AM band loop antenna would consume a sizeable fraction of the volume of a portable radio, so a smaller loopstick antenna is used instead. An FM band whip antenna is thought to mar the lines of an automobile, so a discrete but inferior performing antenna is embedded in the window. This paper considers the trade off between size and performance of UWB antennas. Its aim is to demonstrate that the nature of UWB technology is likely to break this general trend and lead to consumer demand for efficient, high performance antennas.
