Yevhen Yashchyshyn, Józef Modelski · 2007
The results of investigation of the semiconductor antenna with electronically reconfigurable aperture has been presented in this paper. The semiconductor antenna means that the antenna utilizes the semiconductor as a substrate, which parameters can be varied. 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 cause in turn a generation of the desired shapes of radiation pattern. It allows to design the electronically reconfigurable antennas. The results of the investigation show that this type of antenna posseses the unique characteristics compared with the conventional antenna arrays.
