TRANSMISSION-LINE NETWORK

摘要

The invention relates to a transmission-line network of the foam stripline type. To reduce dielectric losses in the foam (6, 7), at least a part of the foam in the region of the stripline (1) is removed such that the wave properties of the transmission-line network are not impaired. Moreover the ducts (9, 10) that are formed may be used for the forced cooling of the stripline (1) using air or another cooling agent.
