Abstract

A novel dual-band bandpass filter (BPF) with a dual-plane structure is proposed. The dual-plane structure consists of a pair of microstrip feed lines with capacitive source-load coupling on the top layer and a meander multimode defected ground structure resonator (MMDGSR) on the bottom layer. Using the intrinsic characteristics of the MMDGSR, two passbands and four transmission zeros can be generated simultaneously. An experimental dual-band BPF operating at 2.45/5.8 GHz (WLAN application) has been designed and fabricated. This performance is verified by good agreement between the simulated and measured results.
