Optically Switched Frequency for Reconfigurable Dipole Antenna Using Photodiode Switches

Abstract: The design, fabrication, and measurement of reconfigurable antenna using photodiode switches have been investigated. The antenna had dimension 104 mm x 41 mm x 1.6 mm and FR4 substrate with relative permittivity 4.8. It structure was Coplanar Stripline (CPS) dipole. Two photodiodes had assembled on gap in both dipole arms, which was activated by 650 nm red laser. There was shifting frequency and return loss at under illuminated by laser. The experimentally and theoretically result for the proposed reconfigurable antenna are having a good agreement with large frequency shifting. The fabricated antenna was easily fabricated, simple structure, and possible to realize in many application of Wi-fi communication which using optical switching.
