Abstract
This work presents a miniaturized bandpass filter in V-band using integrated passive device (IPD) technology with thick metal layers and Benzocyclobutene (BCB) dielectric on a glass substrate. The proposed filter, comprised of two stepped-impedance resonators with quarter-wave short-circuited stubs and floating pads, has low passband insertion loss and high stopband attenuation in a compact size. The fabricated filter has an insertion loss of 2.46 dB at the center frequency of 59 GHz, and a 3 dB bandwidth from 55.7 to 62.2 GHz. The core size of this filter is only 0.32 × 0.4 mm 2 (0.064 × 0.08 λ 0 2 ). © 2011 IEEE.
