Abstract :
A polarisation reconfigurable circular polarised (CP) antenna for GPS application is designed and built using four photoconductive switches. By controlling the ON/OFF state of each of the four photoconductive switches on patch antenna, the polarisation of antenna can be switched from linear (LP) to CP, and from left hand CP (LHCP) to right hand CP (RHCP).
