This article presents a design approach of a band‐pass filter which is fabricated on an integrated passive device process and is capable of operating over the unlicensed 60‐GHz band (57–64 GHz). The band‐pass filter proposed in this article evolves from a typical one comprising two identical, mirrored open‐loop half‐wavelength microstrip line resonators. The experimental results demonstrate an insertion loss of less than 2.4 dB, a return loss of better than 10 dB over the 60‐GHz band, and a 3‐dB bandwidth of 24 GHz (∼42%). The simulation and measurement results are well matched up to 110 GHz. This filter is suited for system‐in‐a‐package V‐band front‐end systems. © 2016 Wiley Periodicals, Inc.
