This article describes the design of on‐chip bandpass filter (BPF) with split ring resonators (SRRs) for millimeter wave application. SRR is one of the metamaterial structures commonly used in designing the passive component and is used to improve the performance of the device. In this design, the BPF is designed with two (2) and five (5) SRRs to analyze the effect of SRRs toward enhancing the performance of the BPF. The SRRs are constructed along the resonator line below the BPF structure on the second lowest metal. In this article, it is shown that the magnetic resonance frequency shifted and leaded to improvement in the insertion loss of BPF as the number of SRRs increased to five. For BPF with 5‐SRRs, the insertion loss is 2.02 dB with return loss better than 30 dB, whereas for BPF with only 2‐SRRs, the insertion loss is 3.29 dB with return loss better than 50 dB. © 2013 Wiley Periodicals, Inc.
