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.
