Definitions

  • the present invention relates to a probe arrangement.
  • the present invention relates to a probe arrangement for a probe-fed patch antenna.
  • Probe-fed patch antennas are a particular type of radio antennas which typically have a flat sheet or "patch" of an electrically conductive material, wherein the electro-magnetic radiation emitted by the patch is caused by a probe or a probe arrangement effecting currents in the patch. Furthermore, patch antennas are typically resonant, narrow band structures.
  • a probe arrangement which is in particular for a single electrically conductive patch and which comprises a foot and a top and at least a first probe and a second probe, wherein the first probe and the second probe are electrically separated from each other.
  • Each probe comprises a feeding portion, an intermediate portion and a termination portion.
  • the feeding portion extends from the foot to the top, in particular in a first direction.
  • the intermediate portion and the termination portion are arranged at the top.
  • the intermediate portion extends at the top from the feeding portion to the termination portion in a second direction that is in particular different from the first direction.
  • a width of the termination portion in a third direction perpendicular to the second direction and in particular different from the first direction is larger than a width of the intermediate portion in the third direction.
  • the probe arrangement according to the first aspect may be configured to extend in all three dimensions. This facilitates achieving a second resonance when combining the probe arrangement with a single patch while maintaining a compact design of the probe arrangement, thereby making the probe arrangement according to the first aspect suitable for applications having strict size limitations. Furthermore, the compact design allows for placing four or more of the probes underneath a single patch, which particularly allows the probe arrangement according to the first aspect to be used for forming a dual-polarized patch antenna.
  • the probe arrangement comprises four or more probes.
  • Having four or more probes is particularly advantageous in that it allows a single patch fed by the probe arrangement to emit dual-polarized radiation.
  • the intermediate portion and the termination portion of the probes are symmetric with regard to a symmetry plane perpendicular to the second direction, wherein the symmetry plane extends in particular through a center of the probe arrangement.
  • the intermediate portion and the termination portion of the probes are symmetric with respect to a main polarization plane, thereby improving the characteristics of the radiation pattern emitted by a single patch that is fed by the probes of the probe arrangement.
  • the intermediate portion and the termination portion of each probe form an arrow-shape.
  • the probes of the probe arrangement allow for a particularly compact design which facilitates using the probes of the probe arrangement with a single patch while keeping the probes of the probe arrangement electrically big enough to have the needed inductance to compensate the probe to patch capacitance and to provide for the second resonance, thereby achieving broadband characteristics.
  • the probes are evenly distributed around a centerline of the probe arrangement, the centerline of the probe arrangement extending in particular in a vertical direction through a center of the probe arrangement.
  • the characteristics of the radiation pattern emitted by a single patch that is fed by the probe arrangement is improved as the probes of the probe arrangement are symmetric with regard to a rotation around the centerline about a predetermined angle determined by the number of probes.
  • each feeding portion has two input ports.
  • each PA provides the same or a substantially same differential input signal to the probes of the probe pair, thereby lowering the power handled by each PA as the output power of different PAs providing the same input signal to the input ports of a single probe may be combined in the feeding portion of the probe to which the intermediate and the termination portion are connected in series.
  • each probe may also have three, four or more input ports, thereby further reducing the power output required from the three, four, or more PAs, respectively.
  • the impedance of a probe pair may be adjusted by changing the distance of the probes of the probe pair, so that PAs with even lower output power can be used.
  • the low impedance of the probe pairs further simplifies the circuitry needed for interconnection with the PAs, reduces the losses and increases the operating bandwidth.
  • the probe arrangement further comprises a dielectric support, wherein a bottom side of the dielectric support forms the foot of the probe arrangement and a top layer of the dielectric support forms the top of the probe arrangement.
  • a maximum cross-section dimension of the top layer is larger than a maximum cross-section dimension of the bottom side and the intermediate portion and the termination portion of each probe lie preferably within an outer edge of the top layer when seen from foot to top.
  • bottom side is intended to be understood in a broad sense referring to an actual surface of the dielectric support as well as to a virtual surface of the dielectric support, a virtual surface being a planar area having a contour that bisects a closed peripheral edge of the dielectric support and in particular a planar area having a contour that bisects an edge of a tube of the dielectric support.
  • the probes are attached to a top surface (area) or a bottom surface (area) of the top layer or are at least in part integrated into the top layer.
  • Attaching the probes to or integrating the probes into top or bottom surface(s) (areas) of the top layer allows to plate, print or laminate the probes onto the dielectric support or into an etched, cut-out, cast, or molded recess in the dielectric support and relaxes the requirements imposed on the probes as compared to self-supporting probes which are also contemplated.
  • the dielectric support comprises dielectric spacers which are arranged on the top surface of the top layer and which are configured to receive a (single) electrically conductive patch.
  • the dielectric spacers allow for attaching the (single) patch on the probe arrangement in a simple and thus efficient manner while ensuring a pre-determined distance as well as isolation between the (single) electrically conductive patch and the probes.
  • the dielectric support has an aperture, wherein the aperture is preferably located at a center of the top layer.
  • Having an aperture in the dielectric support, in particular in the top layer of the dielectric support, allows guiding the feeding portions of the probes through the aperture from the top surface of the top layer of the probe arrangement.
  • the feeding portions extend along an inner surface or an outer surface of a tube connecting foot and top, wherein a circumferential edge of the tube is preferably attached to an inner edge of the aperture.
  • the feeding portions may be plated, printed or laminated onto the inner surface or the outer surface of the tube or into an etched, cut-out, cast, or molded recess in the tube, thereby further relaxing the requirements imposed on the probes as compared to probes with self-supporting feeding portions which are also contemplated.
  • a total height of the probe arrangement is less than a tenth of the wavelength for a central frequency of the probe arrangement, the central frequency being 700Hz or more, 1600 MHz or more, 2200 MHz or more, or 3200MHz or more.
  • the probe arrangement has an ultra-flat design that can be used for designing a broadband patch antenna by combing the probe arrangement with a patch antenna, making it possible to use the probe arrangement and in particular a patch antenna comprising the probe arrangement in typical frequency bands used in mobile communications such as 790-960 MHz, 1710-2170 MHz, 2300-2700 MHz or 3300-3800 MHz.
  • a probe-fed patch antenna which comprises the probe arrangement according to the first aspect as such or which comprises the probe arrangement according to any preceding implementation form of the first aspect and which comprises a (preferably single) electrically conductive patch.
  • the probe-fed patch antenna comprises the dielectric support according to any one of the sixth to the ninth implementation form of the first aspect, wherein the (single) electrically conductive patch is arranged on the top surface of the top layer.
  • Having the (single) electrically conductive patch arranged on the top surface of the top layer and the probes attached to the bottom surface of the top layer or at least in part integrated into the top layer facilitates enforcing and maintaining a pre-defined distance between the patch and the probes.
  • the dielectric support, the probes, and the (single) electrically conductive patch are formed as one piece and are in particular formed from different materials.
  • Having the dielectric support, the probes, and the single electrically conductive patch formed as one piece allows manufacturing the probe-fed patch antenna as a Molded Interconnect Device (MID), thereby making the manufacturing process more efficient than assembling the probe-fed patch antenna from different components.
  • MID Molded Interconnect Device
