A Simple Dual-band Band-pass Microstrip Filter

Abstract

Wireless communication has been gaining a lot of attention since this technology came into human lives with many successful military tools and popular commercial products. For the purpose of enhancing wireless communication performance, especially with dramatically increasing needs from industrial, scientific and medical (ISM) groups, this paper in particular concentrates on the development of a simple interdigital-hairpin-structured microstrip filter, with dual-band pass-bands located at specific frequencies of 2.4 GHz and 5.2 GHz.
