Coplanar waveguide-fed band-selective filter for wideband antenna

Abstract

In this study, a coplanar waveguide-fed band-selective filter and a spiral slot antenna have been designed, fabricated, and integrated for the applications of multisystem integration. The antenna module was fabricated on the same plane of the substrate, so that the circuit process and the position alignment could be simplified. The passband responses of the filter ranging below 2.6 GHz and from 5.0 to 6.0 GHz cover most of the commercial wireless communication systems. Simulated results are compared with measurements performed on the antenna module. (c) 2006 Wiley Periodicals, Inc.
