Abstract
Frequency-dependent RF conductivities of surface PIN-diode arrays were extracted for appropriate design of reconfigurable silicon plasma antennas. Two types of 1-mm-long one-dimensional surface PIN diode arrays on silicon-on-insulator substrate were used for an S-parameter measurement from 0.05 to 10 GHz, and the frequency-dependent resistances and conductivities were extracted. It was found that the conductivity increases with increasing frequency; for instance, the RF conductivities at 5 GHz were 6.4 to 13.8 times larger than their DC conductivities. Also, a simple equivalent circuit model was proposed, and a qualitative analysis was made to explain the behaviour in terms of skin depth. The results indicate that we should use RF conductivity rather than DC conductivity for accurate design of silicon plasma antennas.
