Abstract
Abstract The gaps between adjacent MIC carriers or an MIC carrier and the sidewall of a chassis into which the carriers are inserted introduce a series reactance at frequencies at C band and above which causes deterioration of the operation of the equipment containing the MIC carriers. In accordance with the present invention these gaps between adjacent carriers and/or a carrier and the sidewall of a chassis into which the carriers are inserted are effectively short-circuited by providing a groove in and completely around the outer surface of the carrier and inserting therein a flexible conductive gasket so that when the carriers are inserted in the chassis the gaskets between adjacent carriers and/or between a carrier and the chassis sidewall are in contact under compression.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
127 words
A grounding arrangement for a plurality of microwave integrated circuit carriers comprising: a chassis having a bottom wall and at least one side wall extending from and perpendicular to said bottom wall; said plurality of carriers being disposed in said chassis on said bottom wall in an operative relationship, at least adjacent ones of said plurality of carriers having first gaps therebetween perpendicular to said bottom wall; a groove formed in and completely around the outer surface of each of said plurality of carriers at a given distance above said bottom wall; a flexible conductive gasket disposed in each of said grooves, said gaskets of said adjacent ones of said plurality of carriers being disposed in contact with each other under compression to ground said first gaps.
Claim 2
Dependent Claim
127 words

Claim 3
Dependent Claim
127 words
A grounding arrangement for a plurality of microwave integrated circuit carriers comprising: a chassis having a bottom wall and at least one side wall extending from and perpendicular to said bottom wall; said plurality of carriers being disposed in said chassis on said bottom wall in an operative relationship, at least adjacent ones of said plurality of carriers having first gaps therebetween perpendicular to said bottom wall; a groove formed in and completely around the outer surface of each of said plurality of carriers at a given distance above said bottom wall; a flexible conductive gasket disposed in each of said grooves, said gaskets of said adjacent ones of said plurality of carriers being disposed in contact with each other under compression to ground said first gaps.
Claim 4
Dependent Claim
