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.
