Antenna systems with reconfigurable aperture: Concept, analysis and investigation

The results of analysis and investigation of some semiconductor antennas with reconfigurable aperture have been presented in this paper. Discussed solutions have been based on the utilized semiconductor material. It allows to design the electronically reconfigurable antennas. The key element of the reconfigurable antenna is a surface PIN (SPIN) diode whose conductivity changes proportionally to the plasma density. SPIN structures can be activated selectively and causes, in turn, a generation of the desired shapes of radiation pattern.
