Abstract:
This work describes a novel method of data transmission by means of polarization shift keying. It analyzes the system performance in terms of S/N ratio and defines the required antenna cross polarization performance to achieve an acceptable S/N ratio. A theoretical analysis of antenna cross polarization performance is provided. This analysis predicts a dependence of cross polarization upon antenna substrate and angle of observation which is supported by experimental evidence. This work has also enabled accurate design criteria to be successfully applied to the fabrication of a dual feed circular disc antenna for polarization shift keying at 2.45GHz.
