Abstract

A ball grid array is used on a macroscopic scale as a suspended stripline. The array construction comprises a stack of substrate circuit layers with space regions formed between adjoining layers and a number of conductive ball spacer members distributed at predetermined positions at the space regions. The array has structural stiffness and mechanical strength and it provides both thermal and electrical conductivity pathways between layers and is also convenient and cheap to manufacture using existing technology. The array finds utility for various space-borne or terrestrial printed circuit antenna applications.
