  • Transmission-line network
    Patent number: 5724012
    Abstract: Transmission-line network of the foam stripline type. To reduce dielectric losses in the foam, part of the foam in the region of the stripline is removed so that the wave properties of the transmission-line network are not impaired. The removed foam forms ducts that may be used for the forced cooling of the stripline using air or other cooling agents.
