    Abstract

    In this contribution, the combination of Dielectric Rod Waveguide DRW antennas with photomixer-based sources in the terahertz range is studied. They are a cost-affordable and more compact alternative to dielectric lenses, which makes them especially appealing for arrays configurations, either for increasing the generated power or for beam steering applications. DRW antennas are limited in band, since such antennas radiates in the endfire direction only when the fundamental mode is supported. For avoiding such limitation, the use of embedded planar lenses is proposed.
