Abstract
Shielding structures are provided for microwave circuits with substrate members and shield members which are formed from conventional substrates. The shield members are shaped and joined to the substrate members to form conductive compartments that substantially surround the microwave circuits and the compartments are closed with a conductive cover. The substrate members and shield members form parallel-plate waveguides which communicate between the compartments. The loss of these waveguides is increased with air-dielectric posts to obtain greater isolation between compartments.
