A Solid Plasma Antenna Based on Silicon Lateral PIN diodes

Abstract

In this paper, a solid plasma antenna is proposed and analyzed. This solid plasma antenna is composed of silicon lateral PIN diodes, in which the i-region is exposed on the silicon wafer. The lateral PIN diodes in sufficient forward bias could be regarded and analyzed as plasmas, which could be a substitution of traditional metal in antenna structures, due to the carrier density in diodes maintaining at a high level. The solid plasma dipole antenna with bias feeding network has been designed and fabricated. The antenna resonant frequency could shift by step over an octave.
