Beschreibung
Zusammenfassung:	A device comprises an integrated circuit (IC) die, a substrate, a printed circuit board (PCB), an antenna, and a waveguide stub. The IC die is affixed to the substrate, which comprises a signal launch on a surface of the substrate that is configured to emit or receive a signal. The substrate and the antenna are affixed to the PCB, such that the signal launch and a waveguide opening of the antenna are aligned and comprise a signal channel. The waveguide stub is arranged as a boundary around the signal channel. In some implementations, the waveguide stub has a height of λ/4, where λ represents a wavelength of the signal. In some implementations, the antenna includes the waveguide stub; in others, the substrate includes the waveguide stub.
