Abstract

In this article, a triple-mode microstrip bandstop Filter for CDMA (1.9GHz), WCDMA (2.14GHz) and RFID (2.45GHz) is presented. The center frequencies Low insertion loss, integrated structure and deep rejection level in the passband should be mentioned as benefits for this resonator. Good concurrence between the analytical result and experimental results, full-wave simulation, transmission line model has been obtained. The filter structure 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, supported with a perfect conductor ground plan.
