    摘要： An apparatus comprising:
    a ground plane;
    an array of antennas, wherein the array comprises antennas arranged in parallel rows and parallel columns;
    for one or more columns of the antennas in the array, there is an aligned arrangement of coupling elements comprising coupling elements between the antennas in the respective column,
    wherein the coupling elements are separate from the antennas and are electrically floating.

    摘要： A dual-band patch antenna is described. The antenna includes a ground plane. The antenna also includes an inner conductor disposed above the ground plane. The inner conductor forms a high-frequency patch for receiving radio waves at an upper frequency band. The antenna further includes an outer conductor surrounding the inner conductor. The outer conductor and the inner conductor collectively form a low-frequency patch for receiving radio waves at a lower frequency band. The antenna further includes a filter disposed between the inner conductor and the outer conductor. The filter is configured to at least partially block electrical signals at the upper GNSS frequency band and to let pass electrical signals at the lower GNSS frequency band.

    摘要： An antenna system (10) is provided. The antenna system (10) includes a first substrate (12), the first substrate (12) being a dielectric substrate, a first patch (14) on a first surface (16) of the dielectric substrate (12) and a second patch (18) on a second surface (20) of the dielectric substrate (12). The first and second patches (14, 18) are coupled to form a first capacitor with the dielectric substrate (12). A second substrate (11) is coupled to the first substrate (12) and a ground layer (24) is provided on a first surface (26) of the second substrate (22). An antenna feed (28) is coupled to the second substrate (22).
