Abstract
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).
Claims21
An antenna structure, comprising:
- an array pillars formed on a substrate, wherein a height of the pillars varies across the array so that a surface-wave (SW) propagating through the array is transformed into a leaky wave (LW) that radiates from the array.
A method of fabricating an antenna structure, comprising:
- etching or machining an array pillars onto a substrate, wherein a height of the pillars varies across the array so that a surface-wave (SW) propagating on the substrate is transformed into a leaky wave that radiates from the array.
