With the rapid evolution of RF/microwave wireless communication systems, there is a growing demand for front-end modules that are compact, cost-effective, and high-performing. Our research is dedicated to the development of multifunctional RF/microwave components—such as filters, multiplexers, power dividers, couplers, antennas, and baluns—as well as their integrated design. Emphasis is placed on achieving high levels of performance and functionality within compact architectures, targeting applications in next-generation wireless communication systems.
