Abstract

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 2.38 λ g × 3.14 λ g, where λ g is the guided wavelength at 60 GHz.
