Abstract :
Presents experimental characterization of large-aperture coplanar strip-line antennas, including a determination of the two-dimensional horizontal radiation cone and the dependence of the emitted power on the laser intensity and bias. Autocorrelation techniques were used to observe the frequency response of several antenna geometries.
