Design of a Dielectric Rod Waveguide Antenna Array for Millimeter Waves
Tóm tắt
In this manuscript, the use of dielectric rod waveguide (DRW) antennas in the millimeter and sub-millimeter wave range is presented as a solution for covering two issues: getting more radiated power and filling a technological gap problem in the terahertz band, namely a fully electronic beam steering. A 4x4 element array working at 100 GHz fed by a rectangular waveguide is manufactured and measured for showing its capabilities. This topology can be used as a cost-affordable alternative to dielectric lenses in photomixer-based terahertz sources.
