Abstract
We present a novel non-resonant photoconductive antenna for coherent detection of THz radiation. The antenna consists of an interdigitated electrode structure, where every other electrode gap is covered by a second metallization layer. Different substrate materials with different carrier lifetimes are compared. These antennas are easy to use and offer a high degree of freedom with respect to the focusing of both the THz and the gating beam.
