Abstract

The limitation of the slotline antennas for submillimeter wavelengths mainly comes from the requirement on the substrate thickness. For a dielectric constant of eleven the required thickness is ≈ 10 μm at 350 GHz. One way to overcome this problem is to make the slotline antenna on thick substrate and place one more thick substrate from the top, i.e. to make a sandwich slotline antenna. Experimental results on a sandwich slotline antenna at 350 GHz will be presented together with scaled model measurements (at 30 GHz). The effect of an air-gap and a lens will be discussed.
