Abstract: A reconfigurable intelligent surface (RIS) antenna includes an RIS antenna body and a bias circuit. The RIS antenna body includes a plurality of RIS antenna units. The bias circuit is electrically coupled to the RIS antenna units of the RIS antenna body. Each RIS antenna unit includes: a metal pattern, a dielectric substrate and a control unit. The metal pattern and the control unit are formed on the dielectric substrate. The metal pattern has a resonance frequency. The control unit includes at least one metal oxide resistive element. The control unit is electrically coupled to the metal pattern and the bias circuit for changing the resonance frequency of the metal pattern by adjusting a bias applied by the bias circuit.

Abstract: An electromagnetic wave guidance and beam reshaping structure is favorable to incorporate a radiation source antenna into an energy focusing system. The electromagnetic wave guidance and beam reshaping structure includes a substrate, a plurality of metal patterns and a plurality of hollow structures. The substrate includes a central portion and a peripheral portion that surrounds the central portion. The plurality of metal patterns are disposed on the central portion. The plurality of hollow structures are disposed in the peripheral portion. The metal patterns are axisymmetrically arranged with respect to a central axis of the substrate, and the hollow structures are axisymmetrically arranged with respect to the central axis of the substrate.

Abstract: The disclosure relates to a filter including dielectric substrate, ground and microstrip line layers, and signal and ground vias. The ground layer is formed on the dielectric substrate and has a ground plane and signal terminal contacts. The microstrip line layer is located on the dielectric substrate and includes microstrip resonators, common electrode and input and output terminal contacts. The input and output terminal contacts are connected to the microstrip resonators. The signal and ground vias extend among the ground layer, the dielectric substrate, and the microstrip line layer. The signal terminal contacts are connected to the input and output terminal contacts through the signal vias. The ground plane is connected to the common electrode through the ground vias. The filter further includes at least one capacitive coupling unit capacitive-coupled with two of the microstrip resonators adjacent to each other.
