Abstract

A dual-band bandpass filter with quasi-elliptic response using a substrate integrated waveguide for 60 GHz dual-band wireless communication systems is proposed. It is fabricated with standard low-temperature co-fired ceramic (LTCC) technology. The measured results indicate that the filter is operating at 59.78 and 61.56 GHz with fractional bandwidths of 2.1 and 2.2%, and minimum in-band insertion losses of 3.61 and 3.55 dB, respectively. Furthermore, the proposed filter exhibits an electrical size (including the CPW measurement pads) of 2.38λ_g × 3.14λ_g, where λ_g is the guided wavelength at 60 GHz.
