Definitions

  • the invention relates to a multilayer antenna of planar design according to the preamble of claim 1.
  • Patch antennas or so-called microstrip antennas are well known. They usually comprise an electrically conductive base area, a dielectric carrier material arranged above them and an electrically conductive radiation area provided on the upper side of the dielectric carrier material. The upper radiation surface is usually excited by a transverse to the above-mentioned planes and layers feed line.
  • the main cable used is a coaxial cable whose outer conductor is electrically connected at one terminal to the ground conductor, whereas the inner conductor of the coaxial cable is electrically connected to the overhead radiating surface.
  • Multilevel antennas of planar design have become known, for example, as so-called "stacked" patch antennas.
  • stacked patch antennas.
  • it is possible to increase the bandwidth of such an antenna or to ensure resonances in two or more frequency ranges.
  • By such antennas and the antenna gain can be improved.
  • the patch antenna has, for example, in addition to the underlying ground surface and the offset thereto arranged and excited via a feed line radiation surface above the radiation surface with a lateral offset thereto arranged patch surface.
  • the carrier material between the ground and the radiation surface and between the radiation surface and the patch surface located above each consist of a substrate with the same dielectric constant.
  • a patch antenna with carrier layers with different dielectric constants is known, for example, from the publication IEEE TRANSACTIONS ON ANTENNAS'AND PROPAGATION, VOL. 47, NO. 12, DECEMBER 1999, pages 1780 - 1784 known.
  • Foam is used as the upper carrier layer for the upper metallic surface (patch surface). The distance between the upper patch surface and the underlying radiating surface corresponds to the distance between the radiating surface and the lower mass surface.
  • another antenna with a multilayer structure for example, from the US 5,880,694 A known. It comprises a lower ground surface, a dielectric support body seated thereon with a radiator surface located on the upper side. Above the radiator surface, a further dielectric body is arranged, on which an electrically conductive patch surface is provided on the side remote from the lower ground surface.
  • a stripline antenna with a matching arrangement is also known from EP 1 376 758 A1 known.
  • This prior publication describes various embodiments of stripline antenna arrangements.
  • a stripline antenna is described, which has a stepped surface over a ground surface with at least one upwardly projecting panel-shaped projection. Below this panel-shaped projection, a recess in the foam substrate is provided adjacent to the ground surface, on whose overhead boundary surface a strip conductor 6 is provided. Due to the step-shaped raised projection provided in the middle, deeper stairs and, closer to the ground surface, step-like shoulders are provided on two opposite sides, which are provided with the overhead projection together with an electrically conductive layer.
  • the antenna according to the invention has a significant improvement in the antenna properties, compared with simple normal patch antennas. This is all the more surprising since the radiation structure provided at the top of the patch antenna is arranged at an extremely small distance above the radiation surface of the patch antenna and, in a preferred embodiment, may even have a longitudinal and transverse extent which is greater than the radiation surface underneath. In fact, it would be expected in such a case that the patch surface located to the top adversely affects the radiation pattern.
  • Another essential advantage of the antenna according to the invention is that commercially available patch antennas with a ground plane and a radiation surface and a dielectric located between them, preferably, for example so-called ceramic patch antennas, can be used which need not be structurally modified. It is only necessary to fix the inventive three-dimensional electrically conductive structure of the uppermost patch surface on a commercially available patch antenna by means of a suitable adhesive and / or attachment layer.
  • an adhesive layer in the form of a double-sided adhesive tape or in the form of a comparable adhesive or stapler is used as an adhesive structure between a commercially available patch antenna and the uppermost located three-dimensional conductive patch element, whereby a problem-free attachment of the uppermost patch element on a conventional Patch antenna is possible.
  • the distance between the three-dimensional patch element and the radiation surface of a patch antenna at a distance which is greater than 0.5 mm, in particular greater than 1 mm, for example, by 1.5 mm. Although the distance may be even greater, basically such a small dimensioned distance between the three-dimensional patch element and the radiation surface of a multilayer patch antenna is fully sufficient.
  • the three-dimensional structure of the patch element can be realized for example by a so-called solid, which in addition to its planar extent (for example, comparable to conventional metal flakes or metal layers) also has a significantly greater height or thickness of one or more millimeters.
  • such a three-dimensional patch element arranged above the radiation surface has one or more parts encircling edge or edge of the footway, whereby a quasi-three-dimensional structure is realized.
  • the patch element provided with a three-dimensional structure can be formed by a sheet metal or stamped part, in which edge portions extending from a flat element are placed upwards, which are oriented transversely and preferably perpendicular to the plane of the patch element.
  • the individual flange or edge sections do not necessarily have to be connected to one another electrically or electrically-galvanically.
  • the given electrical formation of a raised edge element to an adjacent edge element via the substantially parallel to the underlying radiation and ground surface aligned central portion of the patch element.
  • the aforementioned three-dimensional structure (which is called a "three-dimensional" structure because it has a significantly greater material thickness or material height than prior art metal plates or foils) does not necessarily require that the entire body be formed as a so-called solid or as mentioned circumferential edge must be formed circumferentially in the entire edge portion of Puschch für circumferentially. Even sections of edge or web elements are sufficient.
  • recesses or even, for example, a concave deformation of the patch surface facing the radiation surface underneath may be provided in the patch surface itself.
  • recesses may also be incorporated in the patch surface which, for example, protrude from the peripheral edge into the patch surface.
  • a dielectric body made of plastic which is coated with an electrically conductive layer.
  • a thickness or height of, for example, more than preferably 0.5 mm or 1 mm, in particular more than 1, 5 mm, this should at least on a parallel to the radiation surface side, preferably on the zu Radiation surface adjacent side and be provided at its peripheral wall or edge portions with an electrically conductive layer.
