Dielectric rod antennas have advantages as elements of focal plane arrays for imaging applications at terahertz frequencies. As well as good directivity and moderate bandwidth they are readily integrated with diode detectors. To demonstrate these attributes we describe the fabrication of a prototype antenna by laser ablation. Theoretical and measured results are presented for a dielectric rod antenna operating at 600 GHz.
