Claim Text:
1. A millimeter wave transceiver, comprising: an interposer plate having an upper surface and a lower surface; an interconnection network supported on the upper surface of the interposer plate; a printed circuit board having an upper surface and supporting the interposer plate; bumps coupling the lower surface of the interposer plate to the printed circuit board; an integrated circuit chip on the upper surface of the interposer plate; antennas made of tracks formed on the upper surface of the interposer plate; reflectors corresponding respectively to the antennas and positioned on the upper surface of the printed circuit board, each of the antennas being separated from the corresponding reflector by an effective distance on the order of one quarter of a wavelength of a millimeter wave; a first conductive track positioned on the upper surface of the interposer and surrounding one of the antennas; a second conductive track provided on the lower surface of the interposer; a third conductive track surrounding the reflector corresponding to the antenna surrounded by the first conductive track, the third conductive track being electrically coupled to the second conductive track by the bumps; and a network of through vias electrically coupling the first and second conductive tracks to each other.
