In this paper, the multipactor RF breakdown in a parallel-plate waveguide partially filled with a ferrite slab magnetized normal to the metallic plates is studied. An external magnetic field is applied along the vertical direction between the plates in order to magnetize the ferrite. Numerical simulations using an in-house 3-D code are carried out to obtain the multipactor RF voltage threshold in...
This work presents the design, fabrication and measurements of a W-band linear array of planar antennas. The structure of the antenna, which presents as benefit low cost and easy manufacture, is composed of three planar patches fed by slots. The simulation and the experimental results are compared showing a good agreement. In order to enhance the radiation properties, a chiral metamaterial cover is...
