Abstract

In this paper, a compact diplexer based on coupled stepped impedance resonators (SIRs) is designed for Digital Communication System and the industrial, scientific and medical applications. The diplexer is composed from two band-pass filters operated at 1.8 and 2.45 GHz respectively. The size and the position of the SIR and the feed lines are determined through the theoretical design and the simulation. The diplexer has less than 2.2 dB insertion loss and more than 21 dB of isolation. The diplexer performances are investigated numerically by using Momentum ADS Agilent and CST microwave software. The electromagnetic simulated results of the proposed diplexer show a good agreement with the measured results.
