Abstract :
The design and fabrication of a leaky-wave antenna at 212 GHz with a dielectric waveguide as the guiding structure is described and some measured results are presented. At this frequency, previously reported approaches for fabricating such an antenna present certain difficulties, which have been overcome using some innovations. This antenna is expected to be useful for radiometry and, consequently should have small beamwidth, high efficiency, and large beam scanning with frequency. It is shown how these can be achieved
