## Abstract A new dual‐band bandpass filter (BPF) for 2.4/5.2 GHz WLAN systems using two‐stepped impedance resonators is presented. With new properly coupled structure, this filter appears very compact and easy to be fabricated. Measured results show that this BPF has low insertion loss of 0.3 dB a

## Abstract In this article, a series of compact dual‐band bandpass filters are proposed using the stepped‐impedance stub loaded hexagonal stepped‐impedance resonator. The resonator has three functions in the filter as follow: (1) dual‐resonances operation introduced by the first‐ and second‐resona
## Abstract We propose a compact dual band bandpass filter (BPF) using meandering stepped impedance resonators (SIRs). By appropriately selecting the impedance ratio (K) of the SIR, the harmonic frequencies can be tuned for generating the dual‐passband response. Using this structure, the bandwidth
