Abstract

In the paper, a dual-bandpass filter for ship's wireless LAN has proposed, which was designed by using step stub in compliance with 2.4 GHz and 5.2 GHz band The dual-bandpass filter can be designed by adjusting the sizes of the step stub in compliance with the frequency bands of 2.4 GHz and 5.2 GHz, which has the improved performance compared with the existing dual-bandpass filter. Furthermore, dual-bandpass filter using step stub has better efficiency. The measured results for the fabricated dual-bandpass filters agreed well with the simulated ones, and hence it was confirmed that the proposed design method is valid.
