Dual‐band planar bandpass filter, using two microstrip rectangular ring resonators, is proposed for wireless LAN system such as IEEE 802.11 systems (2.4 or 5 GHz). The miniaturized bandpass filter is implemented using a high permittivity dielectric substrate. The full‐wave simulator IE3D is used to design the two coupled rectangular ring resonators. The responses of the implemented filter using Zr 0.8 Sn 0.2 TiO 4 ( ε r = 37, tan δ = 0.00012) dielectric substrates are designed at dual‐band frequencies of 2.35 and 4.7 GHz. The compacted size and good agreement have been obtained between simulations and implementation results. © 2007 Wiley Periodicals, Inc.
