A NEW BALANCE-FED DISC-SLIT MONOPOLE ANTENNA FOR MODERN WIRELESS SYSTEMS

摘要

This article proposes a novel balance-fed disc-slit monopole antenna for modern wireless systems. The compact antenna is realized by merging a single-ended disc-slit monopole antenna with a defected-ground balun. The resulting antenna has the special merits of high immunity against electromagnetic interference from nearby circuits and less sensitivity to size variation of the corresponding ground plane. A prototype was created and examined, and the results obtained demonstrate the promising performance of the newly proposed antenna.
