With a total of three patents to his name, Cheng's work focuses on enhancing signal quality in communication systems.

Latest Patents

One of Cheng's latest patents is a filter device and equivalent filter circuit thereof. This invention discloses a filter device that comprises a substrate, at least one transmission conductor, and a reference conductor with a slotted structure. The substrate features a transmission conductor on one surface and a reference conductor on the opposite surface. The slotted structure includes a frame portion, a slotted portion, and a hollow portion, with at least one impedance unit configured on the frame portion. This design allows the equivalent filter circuit to absorb noise at specific frequencies, thereby improving the transmission quality of signals.

Another significant patent by Cheng is the common-mode signal absorber. This invention includes an impedance-matching network and a common-mode signal reflection circuit. When a common-mode signal is inputted, the reflection circuit reflects the signal within a specific frequency band. The impedance element of the impedance-matching network then absorbs the reflected common-mode signal, preventing interference with signals transmitted in communication systems.
