Abstract: Disclosed are exemplary embodiments of multiband MIMO vehicular antenna assemblies. In an exemplary embodiment, a multiband MIMO vehicular antenna assembly generally includes a chassis and an outer cover or radome. The outer cover is coupled to the chassis such that an interior enclosure is collectively defined by the outer cover and the chassis. An antenna carrier or inner radome is within the interior enclosure. The antenna carrier has inner and outer surfaces spaced apart from the chassis and the outer cover. One or more antenna elements are along and/or in conformance with the outer surface of the antenna carrier so as to generally follow the contour of a corresponding portion of the antenna carrier.

Abstract: Antenna module for frequencies in the GHz-range mountable on vehicles features a wide range of functions. Module includes a lower patch-antenna with a lower dielectric substrate. A lower ?/2-antenna structure is on the upper surface of the lower substrate for reception of satellite-transmitted frequencies in the GHz range, and a metallization is on the lower surface of the lower substrate. An upper patch-antenna of smaller dimensions and with an upper dielectric substrate is on the lower patch-antenna. An upper ?/2-antenna structure for reception of satellite-transmitted frequencies in the GHz-range is on the upper surface of the upper substrate. A metallization is below the upper substrate. A lower antenna connector runs from the lower ?/2-antenna structure through the lower substrate. An upper antenna connector separate from the lower antenna connector runs from the upper antenna structure through the upper substrate and the lower patch antenna.

Abstract: By providing a thermal protocol that involves two steps prior to any isolation steps in a metal oxide semiconductor process, induced stress may be reduced between the bulk silicon and overlying areas, such as epitaxial layers. As a result, the dislocations in the overlying area may be reduced.

Abstract: A method is described for improving the exposure focus for modern steppers used in the lithography of semiconductor substrates such as wafers. A wafer is sawed from a semiconductor ingot in a particular direction relative to a reference point on the ingot. As a result of the sawing, a series of raised and recessed formations manifest on the surface of the wafer. After various layers have been added to the wafer and the photoresist layer is ready to be removed, the wafer is aligned with the stepper so that a dynamic focus area of the stepper is aligned with the formations and/or the sawing direction. Such alignment improves the critical dimension control and reduces variability in printing small geometry features during lithography, resulting in higher yields.

Abstract: The invention consists of a flat mobile antenna for frequencies in the GHz-range. The flat antenna comprises first and second partial surface segments made from electrically conductive material, and separated from each other by a gap. The antenna also comprises a ground plane surface spaced substantially parallel to, and arranged below the first and second partial surface segments. The first and second partial segments are connected to the ground plane surface by two short-circuit-like conductors at a right angle. Connected to the second partial segment is a coaxial antenna cable having a center conductor and an outer shield conductor. The outer shield conductor is connected to the ground plane surface, and the center conductor is connected to the second partial surface segment at an input feed point, forming a galvanic connection.

Abstract: A flat antenna for mounting on windowpanes of motor vehicles reduces the dimensions of the mass reference area of the mass plane, and the structural height without unfavorably influencing the functions and operating parameters of the antenna. The mass reference area has a trough-like shape, is centrally positioned under an aerial segment, and has conductive coating impermeable to the operating frequency of the antenna. The inside and outside conductors of the coaxial feed cable are connected to the aerial segment and mass reference area shifted to outside the aerial elements and thereby enables a significant reduction in overall dimensions.
