Design of polarization reconfigurable microstrip antenna with frequency tuning

This paper presents a polarization reconfigurable microstrip antenna with frequency tuning. A method is investigated to achieve frequency reconfigurability by etching a rectangular ring slot in a corner truncated polarization reconfigurable antenna. Reconfigurability is achieved by electronic switching with the help of solid state device such as PIN diode. The concept is validated by simulation results. Return loss, axial ratio and gain characteristics of linear, right hand circular polarization and left hand circular polarization states are presented at dual frequency.
