Abstract

Shielded single and multilayer coplanar waveguide lowpass filter on GaAs and Si substrates in MMIC technology is presented and their performance is investigated with electromagnetic simulations. The filters are both Chebyshev type. The stepped‐impedance method is used in the design of the lowpass filter, where high‐ and low‐impedance line sections are cascaded together. The shielded single‐layer lowpass filter consists of three low‐ and two high‐impedance sections with characteristic impedances of 20Ω and 100Ω. The multilayer filter makes use of three low‐ and two high‐impedance lines with characteristic impedances of 5Ω and 120Ω, respectively. © 2003 Wiley Periodicals, Inc.

## Abstract In this paper, we design and implement a coplanar waveguide (CPW) bandpass filter utilizing defected ground structure (DGS) technology. The CPW DGS technology, which only needs one or a series connection of a few cells to exhibit the bandgap characteristics, can provide the attenuation
