Abstract :
This paper deals with the modeling and characterization of a broadband frequency agile metamaterial-based cavity antenna around 2 GHz. An electronically active metasurface is used as a Partially Reflecting Surface (PRS) and the cavity is excited by an array of four wideband L-strip fed printed microstrip patch antennas. A reconfigurable resonance frequency between 1.9 and 2.31 GHz is obtained and a directivity of 18 dBi is observed for a cavity thickness of λ/10 at 2 GHz.
