Abstract
This paper presents a compact and novel dual-band bandpass filter (DBBPF) using a microstrip dual-mode resonator, folded stepped impedance resonator (SIR) and an etched ground structure (EGS). The first and second passbands are generated by the dual-mode and single-mode resonators. The proposed bandpass filter (BPF) produces passbands centered at 2.4 GHz and 3.5 GHz, respectively. The passband performance of the DBBPF is enhanced by etching a pattern in the ground plane which provides less than 1-dB insertion loss in both of the passbands with more than 20-dB isolation in the stopband. The BPF is analyzed using classical odd–even-mode technique. The simulated full-wave electromagnetic (EM) results obtained using IE3D are in well agreement with the theoretical results. The proposed DBBPF can be employed in WLAN and WiMAX applications.
