Abstract :
A free space optical (FSO)/radio frequency (RF) dual mode communication transmitter using a LED integrated within the geometry of a planar patch antenna on a shared substrate is demonstrated. An experimental FSO link is constructed with a bare die visible LED and a commercial silicon photodetector. The antenna radiating at a centre frequency of 10 GHz, provides a simultaneously operated backup RF channel for the FSO data communication link to enhance reliability. A date rate of 20 Mbits is achieved for the FSO data communication.
