In this paper, various planar printed microwave bandpass filters (BPFs) are designed and analyzed by applying a nonuniform finite‐difference time‐domain (NU‐FDTD) method. These filters, referred to as integrated‐circuit package filters (ICPFs), are designed in such a way that they operate in dual mode (DM), that is, at TM z 100and TM z 010 , to ensure a good electric performance at the center frequency. They operate at 2.4 and 5.25 GHz, which are the frequencies allocated to wireless local area networks (WLANs). The frequency characteristics in terms of the scattering parameters are taken for analysis, and the results are compared to the measurements as well as the computed results using High‐Frequency Structure Simulator (HFSS) software. The results show excellent agreement between the numerical and experimental data, and the proposed DM‐ICPF structures can be applied to on‐package highly integrated wireless transceiver systems. © 2006 Wiley Periodicals, Inc.
