Abstract

A dual-band common-mode filter is proposed to improve the electromagnetic compatibility (EMC) of wireless communication. Implemented in low-temperature co-fired ceramic (LTCC) fabrication as a component, the filter is with a compact size of 3 × 3 mm². The common mode noise can be reduced over 10 dB form 1.3 GHz to 3.2 GHz and from 5.0 GHz to 6.0 GHz, where the most-used wireless communication bands are involved. Besides, insertion loss of differential mode signal is less than 3 dB from DC to 8 GHz, which implies high data transmission quality.
