β¦ Synopsis
Abstract
Two types of selfβresonant antennas, meander and sinusoidal are experimentally characterized. Input impedance, bandwidth, and radiation pattern data for such antennas are given. It is demonstrated that antennas that are 34% shorter than quarterβwave monopoles and have 3.8 dBi of peak gain can be designed with acceptable bandwidth. Β© 2002 Wiley Periodicals, Inc.
