Filed:

Feb 17, 1994

Appl. No.:

8/198410

Inventors:

David E. Hammers - Los Angeles CA
Michael D. Conway - Roanoke VA

Assignee:

ITT Corporation - New York NY

International Classification:

H01Q 324

US Classification:

342372

Abstract:

An integrated active array antenna system is disclosed which comprises a "sandwich style" microwave packaging scheme that includes three principal layers: an antenna layer, a transceiver layer, and a beam forming sub array layer. These three layers are arranged in a coplanar geometry, with connections between the layers being in the form of microwave vias. Each transceiver module may be implemented in the form of a single Monolithic Microwave Integrated Circuit, and each beam forming sub array may be similarly implemented. The coplanar geometry and use of Monolithic Microwave Integrated Circuit technology provide for multi-beam active array of very shallow physical depth.

Abstract:

An apparatus for extruding a tubular article from a cellular plastic compound comprising a bushing defining a passage extending therethrough, an internal mandrel within the passage of the bushing and cooperating therewith to define a die passage, and an external mandrel downstream of the internal mandrel. The die passage has a tapered section and an outlet section with the overall width of the tapered section reducing as it extends toward the outlet. The outlet section terminates in an outlet. The gap dimension of the tapered section is greater than the gap dimension of the outlet section. The die passage has a transition section which is of progressively reducing thickness to smoothly blend the tapered section and the outlet section.
