Modeling of lumped and distributed elements for dual-band with harmonic suppression ±90° unit module

This paper presents a lumped and distributed element models for dual-band (f 1 /f 2 ) with harmonic suppression (HS) ±90° unit module. At first, the lumped and distributed element models for the dual-band (2.45/5.2-GHz) unit module are constructed. Then, the scattering parameter responses of the unit models are simulated and compared by using general microwave circuit software, such as Agilent ADS™ etc. Finally, the parameter values of the elements for the unit module are extracted and summarized.
