The goal of this work is to increase the power emitted at E-band by a photomixing antenna array on PCB technology. The antenna architecture has been tailored to obtain a scalable design and a high radiation efficiency, while featuring a relative bandwidth larger than 10%. Our first prototype, with a 3-dB gain bandwidth of 12 GHz and one active photodiode, has been used in a wireless link. This preliminary demonstration has yielded a 2.15 Gb/s error-free data rate transmission for a 25 cm distance.
