The present invention relates to a method of manufacturing a printed wiring board (PWB) of the type depicted in FIG., and to the resulting PWB. Such a PWB comprises a first substrate and alternating layers of a second substrate and a metal layer. The layer 2 metallization of the PWB is a thick layer of a composite engineered metal material having a configurable coefficient of thermal expansion (CTE) to provide CTE matching with respect to radio frequency (RF) components mounted on the PWB, and having substantial heat dissipation properties to dissipate heat generated by the RF components. This composite metal layer also provides a ground plane for the RF components.

Method of making a wiring board having an engineered metallization layer

An antenna and a method of creating multiple polarization states in an antenna comprising providing to the antenna a single power input, dividing the power received from the single power input, and transmitting the divided power to a radiating element via a plurality of transmission lines.

Single input circular and slant polarization selectivity by means of dielectric control

An antenna and a corresponding method of creating any polarization state in an antenna comprising providing to the antenna a single power input, dividing the power received from the single power input, transmitting the divided power to a combiner network via a first plurality of transmission lines, and transmitting power from the combiner network to a radiating element via a second plurality of transmission lines.

Universal antenna polarization selectivity via variable dielectric control

A monolithic thin film variable power divider is disclosed for variable power level distribution. The thin film power divider includes a substrate having a main surface, a first stage and a second stage, each formed as thin film networks on the main surface of the substrate. The first stage includes a plurality of transmission lines, at least one of the transmission lines having a variable dielectric deposition layer providing variable power level distribution. The variable dielectric deposition is a paraelectric, such as Barium-Strontium-Titanate. The second stage includes a hybrid combiner. The thin film power divider is capable of operating at frequencies extending into the millimeter wave spectrum. The thin film power divider provides a cost effective device that varies the balance of power through a multiport RF distribution network while simultaneously maintaining little, or low, frequency dispersion during the dynamic dissemination process.

Dynamic, non frequency dispersive, RF power division by means of variable dielectric material properties

An antenna beam steering apparatus and method comprising providing an antenna, employing a beam-deflecting lens through which energy passing from and to the antenna is deflected, and rotating the antenna with a single-axis rotator.
