Abstract

We describe a novel technique for measuring transient far-field radiation patterns emitted from optically pulsed, broadband, integrated antennas using photoconductive sampling methods. These devices are capable of generating and radiating short electrical pulses which contain frequency components exceeding 80 GHz. The far-field patterns in both the E and H planes are observed to consist of single, forward directed lobes which are shown to have a cosine-squared dependence. In addition, there are no indications of any additional secondary sidelobes in either of the principal planes.
