in this contribution, the use of Dielectric Rod Waveguide antennas in the millimeter-wave range is studied. They can be used in array configurations for both increasing the gain and electronic beam steering. A 4×4 elements array is manufactured as a proof-of-concept. This topology can be used as a cost-affordable alternative to dielectric lenses for photomixer-based terahertz sources. The use on such...
The theoretical background of antenna theory, especially in relation to terahertz applications, is presented in this chapter. A general discussion of the issues of THz antennas, especially when matching the photomixer is presented. Array theory is presented, together with an exhaustive and precise analysis of one of the most promising new solutions for generating THz emission with high power levels,...
In this contribution, the use of Dielectric Rod Waveguide antennas integrated with a THz photomixer-based emitter is studied. This topology presents a cost-affordable alternative to dielectric lenses for reducing losses caused by scattering into the substrate and reflection in the semiconductor-air interface. For increasing the bandwidth, the use of planar dielectric lens embedded into the rod is...
