Stefano Vacarro has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8558740
    Abstract: In an exemplary embodiment, an antenna architecture comprises a single aperture having both receive elements and transmit elements, where the single aperture has the performance of a dual-aperture but in about half the size. Moreover, in the case of an array with inclined elements, there is the need to interconnect a planar substrate with an inclined substrate at an angle. An exemplary single aperture comprises a metal core having a thick pass-through slot from a first side to a second side; connecting the inclined substrate to the first side of the metal core, and connecting a second substrate to the second side of the metal core. Furthermore, an RF signal is communicated between the first substrate and the second substrate in a contactless manner through the thick pass-through slot.

  • Patent number: 8410980
    Abstract: In an exemplary embodiment, a phased array solid-state architecture has dual-polarized feeds and is manufactured, for example, on highly flexible silicon germanium (SiGe). The implementation of dual-polarized feeds facilitates the operation of phased arrays where the polarization can be statically or dynamically controlled on a subarray or element basis. In an exemplary embodiment, the sub-component control is configured to optimize a performance characteristic associated with polarization, such as phase or amplitude adjustment. An active phased array architecture may replace traditional distributed and GaAs implementations for the necessary functions required to operate electronically steerable phased array antennas.
