Ship's wireless LAN was in the limelight as equipment of ease, cost reduction, various In the paper. a dual-bandpass filter for wireless LAN has proposed, which was designed by using dual-mode square loop resonator with square patch in compliance with 2.4 GHz and 5 GHz band of wireless LAN. The dual-bandpass filter could be designed by adjusting sizes of one perturbation element and three of reference elements in compliance with the frequency bands of 2.4 GHz and 58 GHz, Furthermore, new dual-bandpass filter was also designed by adjusting stopband if using open stubs in compliance with the frequency bands of 2.4 GHz and 52 GHz. 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.
