Abstract:

Based on the modeling of the lateral PIN diode, the formation mechanism of the solid state plasma is analyzed. Relationships of the solid state plasma parameters, i.e., complex permittivity, conductivity, and carrier density in semiconductor, and physical structure size of the lateral PIN diode are built. Furthermore, the transmission and loss characteristics of the electromagnetic waves in lateral PIN diodes are obtained. An implementation method of the solid state plasma frequency re-configurable antenna is proposed based on the silicon lateral PIN diode, and it could shift the resonant frequency by controlling lateral PIN diodes. The re-configurable frequency range of the fabricated antenna is over an octave by designing and fabricating the re-configurable dipole antenna. The experimental performances are in a good agreement with the simulated results, which indicates that the analysis on the lateral PIN diode is correct, and the implementation method of the re-configurable antenna is feasible.
