Wideband microstrip passband filter by using ADS software

Space mapping is a powerful technique to optimize such complex models by efficiently substituting accurate but expensive electromagnetic models, fine models, with fast and approximate models, coarse models. In this paper, we apply space mapping, an explicit space mapping techniques to Design, a microstrip passband filter. The filter configuration is made of a perfect conductor on the top of a substrate (RT_DURROID_5880) with a relative dielectric constant of 2.21 and a height of 20mil, backed with a perfect conductor ground plane. The proposed passband filter 9GHz to 10GHz is designed and simulated with Advanced Design System (ADS 2010) and was implemented with good compactness and low insertion loss.
