Latest Patents
Rong Cai holds a patent for a "Balanced-type strip-shaped dielectric substrate integrated filter." This invention includes a high-k dielectric substrate, with first and second low-k dielectric substrates and metal grounds symmetrically stacked on its upper and lower surfaces. Compared to existing balanced-type dielectric filters, his design proposes a high Q-value strip-shaped dielectric substrate integrated resonator that operates in TM mode. This resonator employs strip-shaped dielectric blocks with double grooves, combined with air groove structures of upper and lower layers, along with a packaging substrate. This innovation addresses the high costs and self-packaging limitations of existing balanced-type dielectric filters that utilize ceramic dielectric with metal chamber structures. As a result, his invention achieves a balanced-type strip-shaped dielectric substrate integrated filter characterized by low loss, self-packaging capabilities, high integration levels, and reduced costs.
