Abstract

In this article, a new ultraโ€wideband (UWB)โ€integrated antennaโ€filter notched at HiPerLAN 5.8 GHz frequency is presented. This antenna filter system is composed of a rectangular slot fed with a microstrip rectangular patch by coupling effect and cascaded with an UWB interdigital hairpin resonator filter. The proposed components, antenna and filter, are matched with 50 ฮฉ, to allow an easier connection, with no need to add additional matching circuit. To improve the selectivity of the antenna filter system, two wide sections of microstrip line was inserted between the input/output feed lines and the interdigital hairpin resonators of the UWB filter. To validate the proposed concept, a prototype was fabricated and tested. The experimental results are presented and discussed. The obtained results show a good agreement between experimental and fullโ€wave electromagnetic (EM) simulation results. ยฉ 2011 Wiley Periodicals, Inc.
