This letter presents a new approach for reconfiguring substrate integrated waveguide (SIW) devices. It involves allowing or prohibiting the wave propagation by using a removable wall which is built from a series of drill holes. When the wall is requi...

This chapter is concerned with corrugated plate antennas. The corrugated plate antennas, presented here, consist of a resonant slot formed within a metallic plate. The resonant slot is surrounded by a rectangular cavity and corrugations. Subwavelengt... Read More about 3D-printed millimetre-wave antennas with spray-coated metalization.
