    摘要: A multiband patch antenna and a method for receiving radio frequency signals in multiple bands by a multiband patch antenna are disclosed. The antenna comprises a substrate layer having a first surface and a second surface and a base element on the first surface. A multi-resonance patch element comprising a pattern of outward extending resonance formations.is provided on the second surface. At least two proximity feed elements configured for connection to a multiband hybrid coupler circuit and extending within the substrate layer from the first surface to the second surface are also provided. The multi-resonance patch element is configured to leave areas where the proximity feed elements extend to the second surface uncovered by the multi-resonance patch element.

    摘要: An antenna (100) is provided comprising a substrate (110) formed of a dielectric material. The substrate has an upper surface (112), a lower surface (114), and one or more side surfaces (116) connecting the upper surface with the lower surface. The antenna further comprises a conductive patch (120) on the upper surface of the substrate; a first conductive strip (130) on one of the one or more side surfaces; and a second conductive strip (140) on one of the one or more side surfaces. The first and second conductive strips are arranged at opposing sides of the conductive patch. The antenna further comprises a ground plane (150, 152), wherein the first and second conductive strips are galvanically isolated from the conductive patch and galvanically connected to the ground plane.

    摘要: A method is provided for calibrating a vehicle-mounted GNSS antenna. The method comprises measuring a response of the antenna, while the antenna is mounted on the vehicle. Based on the measured response, data characterizing a group delay variation of the antenna is calculated. The data may be used to correct ranging measurements derived from GNSS signals received via the vehicle-mounted antenna. Alternatively or in addition, the data may be used in estimating the integrity of a position fix.
