Abstract: Disclosed are methods for high-throughput screening of cell lines for use in protein expression in certain pharmaceutical, drug development, and biotechnological processes such that high productivity cell lines are identified for their ability to produce both desired levels of protein expression and appropriate quality of a protein-of-interest.

Abstract: A compact, modular limited-scan phased array is disclosed. The entire array, combining the feed and the radiating elements, is fabricated as a multilayer, planar substrate structure, with vias incorporated as layer interconnects. Furthermore, the desired degree of control over the array pattern can be exercised by inclusion of additional feed circuit layers. The feed can be used in systems requiring limited scan in one of the principal scan planes and wide-angle scan in the other plane, as well as in phased arrays with limited field-of-view in both principal scan planes. The planar circuit implementation of the array makes in inherently amenable to integration with state-of-the-art solid-state active components.
