LOW-PROFILE AND HIGH-GAIN MODULATED METASURFACE ANTENNAS FROM GIGAHERTZ TO TERAHERTZ RANGE FREQUENCIES

摘要

A modulated MTS antenna including a metasurface fabricated from metallized cylinders on a ground plane. The antenna structure can be designed to operate in the Gigahertz or Terahertz frequency band and to have a well defined directivity. The MTS antenna may be micromachined out of a silicon wafer using deep reactive ion etching (DRIE).
