Abstract
In one example, an apparatus includes a substrate, an antenna on the substrate, a sealed container enclosing a dipolar gas, a waveguide, and a stub. The waveguide is communicatively coupled between the antenna and the sealed container. The waveguide is separated from the substrate by a gap. The stub is adjacent to the waveguide and extends away from the gap.
