A Novel, FSS-Enhanced, Pop-Up Card Inspired Corner Reflector Antenna

This paper presents a corner reflector antenna with a reconfigurable radiation pattern. The the corner reflector uses a frequency-selective surface (FSS) as has a variable folding angle. The inclusion of the FSS in the reflector design causes nulls to appear 73° from the direction of maximum radiation on both sides. As the folding angle is decreased from 90° to 60°, these nulls deepen, and the difference between the gain at the nulls and the maximum gain increases. The cause of this may be that the FSS is better at reflecting radiation at the resonant frequency than a solid metal reflector.
