Definitions
- the present invention relates to a radar device, preferably for detecting objects enclosed in a wall, which has a transmitting and receiving antenna arrangement consisting of at least one cavity with a radiating element arranged therein and a shielded space for electrical circuits, the shielded space is formed by a printed circuit board covered by a housing, on the side facing the inside of the housing the circuits are applied and on the other side the antenna arrangement is installed.
- Such a radar device is known from WO 96/19737.
- a radar z. B. objects enclosed in a wall or in the ground can be detected with high accuracy. So that z. B. in holes in a wall, the objects enclosed - z. B. steel reinforcements, power lines, water pipes and the like - safe from destruction, the craftsman should be given precise information about a location, ie the path position on the wall surface and the depth in the wall of the enclosed object.
- a radar device as also described in WO 96/19737, usually consists of a "front end" - that is a transmitting and receiving unit - and a display device.
- the front end disclosed in WO 96/19737 has a shielded one, as stated at the beginning Space for electrical circuits and two adjoining this space, which are designed as a transmitting antenna and receiving antenna.
- the cavities for the transmitting and receiving antennas have the shape of horns in which Radiator elements (e.g. in the form of wires) are installed.
- the shielding of the space accommodating the circuits is done on the one hand by a housing placed on the circuit board for the circuits and on the other hand by the walls of the antenna horns which are fixed on the side of the circuit board opposite the circuits.
- the design of the front end of a radar device which can be found in the publication WO 96/19737, is relatively complex in terms of production technology because it consists of a large number of individual parts.
- Herscovici "New Considerations in the Design of Microstrip Antennas", IEEE Transactions on Antennas and Propagation, Vol. 46, No. 6, June 1998, pages 807-812 is a transition line as an electrical connection between a planar The planar antenna at M.
- Herscovici is arranged at a certain distance above the circuit board and consists of a conductive plate (patch) serving as a radiating element, from the edge of which the transition line to a planar line opens The line arm of the transition line can be connected in one piece to the radiating element of the antenna.
- the other end of the line arm which is referred to in the publication as a 3D transition, has a contact foot on its end lying on the circuit board, which for example is connected to the planar lead can be soldered.
- the contact foot resting on the circuit board is not able to give the transition line a high mechanical stability.
- this transition line is not able to hold a planar antenna connected to it with a sufficiently high stability. That is why for the planar antenna requires an additional support post.
- the invention is based on the object of specifying a radar device of the type mentioned at the outset, which is of compact construction and can be implemented in production technology as simply as possible, but with high stability, especially of the antenna element, good electrical transmission properties being desired.
- a single housing which forms both a shielded space for circuits and at least one cavity for at least one antenna radiating element.
- a shielding partition between the two rooms is formed by a circuit board which carries the electrical circuits on one side and the antenna arrangement is installed on the other side. All that is required for the assembly of the front end of a radar device is a printed circuit board on which electrical circuits and at least one radiating element of an antenna arrangement are preinstalled in order to be inserted into a housing.
- the ' features according to the invention not only lead to a simplification in terms of production, but also to a material saving, because the electrical circuits and the antenna arrangement are incorporated in a common housing and separate housing arrangements for the electrical circuits and for the antenna arrangement are therefore superfluous.
- a shoulder is expediently formed on the housing, which serves as a support and for fastening the printed circuit board.
- the housing advantageously has at least one exit or entry opening for radar beams on the side of the at least one antenna cavity facing away from the printed circuit board, and this opening is closed with a dielectric plate that is continuous for the radar beams.
- the housing is formed in one piece, the housing consisting either of metal or of a metallized plastic.
- the electromagnetic shielding between the two rooms can be implemented in a simple manner by means of a metallized layer on or in the printed circuit board.
- a simple to produce radiator element is preferably formed from a sheet metal with a section aligned approximately parallel to the circuit board, from which sheet segments are angled at two opposite edges, which act as line arms for coupling the radiator element to a feed network on the circuit board and as a spacer for the flat section serve over the circuit board.
- the line arms for coupling the radiator element to a feed network on the circuit board advantageously have at their end that can be contacted with the circuit board one or more pins that are oriented essentially perpendicular to the circuit board plane and can be inserted into openings provided therein and can be contacted with the planar line. Due to the pins that can be inserted into the openings in the circuit board, the line arm is very mechanically stable. In addition, the pins can be easily soldered into the openings in terms of process technology, so that a permanent, less fault-prone contact between the transition line and a planar line can be produced on the printed circuit board.
- An improvement in the electrical contact between the transition line and the planar line and also the mechanical stability of the transition line can be achieved in that there is at least one further pin extending from the line arm, which is angled perpendicularly with respect to the other pin (s), so that when the line arm is inserted into the circuit board, it lies on a conductor track of the planar line and can thus be contacted.
- the transition line consisting of the line arm and the contact means, can be formed as a one-piece part, preferably made of sheet metal.
- the transition line according to the invention can advantageously be used for an electrical and mechanical connection between a printed circuit board and one at a distance Use a planar antenna located above the circuit board.
- FIG. 1 shows a longitudinal section through the front end of a radar device
- FIG. 2 shows a perspective illustration of a radiator element which can be inserted into the front end
- Figure 3 is an exploded view of a transition line of a radiator element and a multi-layer circuit board and
- Figure 4 shows a cross section through a multilayer printed circuit board with a transition line inserted therein.
- a radar device which is provided for detecting objects enclosed in a wall. If there is talk in the application of wall inclusions which are to be tracked down with the radar device, the use of the radar device is therefore not restricted to walls, but also extends to comparable areas, such as, for. B. ceilings or floors.
- a radar device usually also has a display part, where location information about a tracked object can be displayed in a wall. The display unit will not be discussed in more detail here, since it is not the subject of the invention.
- a frontend means the part of the device in which all transmit and
- Receiving facilities are housed. Circuits, e.g. B. digital signal processors for processing the received signals can be arranged in the front end; but they can also be accommodated in a separate part of the device.
- the front end of the radar device has a housing 1 in which all parts belonging to the front end are housed together.
- the front end essentially consists of two component groups. One group of components are electrical circuits for processing high-frequency signals or low-frequency signals or digital signals.
- the second module of the front end consists of a transmit and receive antenna arrangement.
- the two different modules mentioned are accommodated in rooms 2 and 3 of the housing 1 which are separate from one another and shielded against electromagnetic radiation.
- the housing 1 is shaped so that the two rooms 2 and 3 are arranged one above the other.
- the electrical circuits 4 are accommodated in the upper space 2, these circuits 4 being arranged on a printed circuit board 5.
- This circuit board 5 is fixed in the housing 1 at its edges and represents a partition of the room 2 shielding from electromagnetic radiation with respect to the room 3 below the circuit board 5.
- the circuit board is 5 provided with one or more metallized layers. This at least one metallized layer can either be applied to the outside of the circuit board or inside the PCB 5 run. In the exemplary embodiment shown in FIG. 1, such a shielding metallic layer 6 is arranged in the interior of the printed circuit board 5.
- a simple possibility of fixing the printed circuit board 5 in the housing 1 is provided in that a circumferential shoulder 7 is molded onto the housing 1.
- This shoulder 7 gives the housing 1 a stepped shape, as the longitudinal section shown in FIG. 1 shows.
- the dimensions of the two rooms 2 and 3 arranged one above the other are therefore of different sizes.
- the edge of the printed circuit board 5 rests on the shoulder 7 and can be fastened there with fastening elements (for example screws, rivets) 8, 9 or by soldering or gluing or other suitable fixing means.
- the cavity 3 located below the circuit board 5 serves as a transmitting and receiving antenna.
- a radiator element 10 belonging to the transmitting and receiving antenna is located in the cavity 3 and is fastened to the side of the printed circuit board 5 opposite the electrical circuits 4 and is electrically contacted with a feed network (not shown).
- the dining network is in the simplest case, for. B. from a
- Stripline branching via which an electrical connection between the antenna and transmitter or receiver circuits is established.
- it is an antenna with a single radiating element 10 which both emits and receives radar beams.
- a transmitting and a receiving antenna can be designed separately from one another.
- the cavity 3 would be divided into two subspaces, each of which would be equipped with its own radiating element.
- the housing 1 is open on the lower side, where radar beams enter and exit. This opening is closed by a dielectric plate 11 which is continuous for the radar beams and has the function of a radome.
- each of these adjacent subspaces would be provided with an opening, which would expediently be closed with a dielectric plate.
- the connection of the housing 1 to the dielectric plate 11 can be realized in very different ways. Lanyards can e.g. B. screws, rivets, glue, solder or the like. Additional fastening means for the dielectric plate 1 can also be molded onto the housing 1.
- FIG. 2 shows a special exemplary embodiment of a radiator element 10 in perspective below the printed circuit board 5.
- the radiator element 10 consists of a flat section 12 aligned approximately parallel to the printed circuit board 5.
- the flat section 12 can have a rectangular shape (as shown in FIG. 2); but it can also have a round, oval or similar shape.
- the emitter element is preferably manufactured as a stamped sheet metal part.
- two sheet metal segments 13 and 14 are angled, which serve as line arms for coupling the radiator element 10 to a feed network (not shown) on the printed circuit board 5 and as a spacer for the flat section 12 above the printed circuit board 5.
- the bent ends of the sheet metal segments 13 and 14 serve to rest on the Circuit board 5.
- contact pins 15, 16 which can be inserted into associated openings 17, 18 in the printed circuit board 5 and can be contacted there with corresponding conductor tracks of a feed network.
- radiator element 10 not only establishes an electrical contact with a feed network, but also the radiator element 10 is fastened to the underside of the printed circuit board 5.
- an additional soldering lug 19 can be provided at the ends of the sheet metal segments 13 and 14, which can be soldered onto a conductor track on the underside of the printed circuit board 5.
- the flat section 12 of the beam element 10 is held at a certain distance above the printed circuit board 5 carrying a feed network. There is therefore a dielectric with very low permittivity, namely air, between the flat section 12 and the printed circuit board 5, which enables very broadband operation of the antenna.
- the bandwidth of the antenna can be optimized in that, as can be seen in FIG. 2, the flat section 12 has tongue-like extensions 20 to 27 in addition to the line arms 13 and 14.
- two extensions 20, 24; 21, 25; 22, 26; 23, 27 arranged side by side.
- the two extensions arranged side by side improve the adaptation of the antenna in the direction of lower frequency ranges. Deviating from the illustrated embodiment, can also only laterally from the line arms 13 and 14 an extension 20, 21, 22, 23 can be provided. They alone also bring about an adaptation which improves the bandwidth of the antenna. If very broadband operation of the antenna is not required, all extensions can also be omitted.
- FIG. 2 shows that at each corner of the flat section 12 one of the extensions 24, 25, 26, 27 is bent out over the flat section 12.
- These bent-out extensions 24, 25, 26, 27, which act like resilient tongues, support the radiator element 10 with respect to the dielectric plate 11 lying underneath it (see FIG. 1).
- the housing 1 can consist of a stamped and bent sheet; but it can also be manufactured using die casting or injection molding technology.
- the material is either made entirely of metal or from a metallized plastic.
- connector elements or other parts required for the complete assembly of the radar device can also be molded onto the housing 1.

- the conductive layer 6 present between the two dielectric layers 30 and 32 is electrically connected to the outer conductor 35 of the coplanar line via a plurality of plated-through holes 38 introduced into the dielectric layer 30.
- a more than two-layer printed circuit board or only a single-layer printed circuit board can also be used in connection with the transition line described in more detail below.
- the planar line type shown in FIG. 3, namely the coplanar line, is also not a prerequisite for the use of the transition line.
- any type of planar line (for example microstrip line, slot line and the like) running on a printed circuit board is suitable Question.
- a transition line 39 is shown in FIG. 3 in an exploded view above the planar line 34, 35.

- the radiator element 10 is arranged at a distance above the printed circuit board 5, since the antenna for its broadband operation uses the dielectric Air is required between the printed circuit board 5 and its radiator element (patch) 10.
- the transition line 39 consists of a line arm 14 bent out of the plane of the circuit board 5.
- the line arm 14 is connected to the radiator element 10 at its end which projects above the circuit board 5.

- Openings 36, 361 and 40, 42 are provided in the dielectric layers 30 and 33 for the two pins 16 of the line arm 14 which are oriented perpendicularly to the printed circuit board 5 and into which the pins 16 of the line arm 14 can be inserted. Also in the inner conductor 34 of the coplanar line on the dielectric layer 30 there are recesses 44 and 46 through which the pins 16 can penetrate the openings 36, 361, 40 and 42 of the dielectric layers 30 and 32.
- the radiator element 10 as can be seen for example in FIG. 2, has two transition lines 39, which ensure a mechanical and electrical connection of the radiator element to the printed circuit board 5 of the arrangement via the line arms 13 and 14, respectively.
- the cross section shown in FIG. 4 through the printed circuit board 5 shows a transition line 39 inserted therein and a pin 16 on the line arm 14, which connects the inner conductor 34 of the coaxial line, the dielectric layers 30 and 32 and the conductive layer 6 lying in between penetrates.

- the openings 36, 361, 40 and 42 in the dielectric layers 30 and 32 can be contacted with the inner conductor 34 on the upper side of the printed circuit board 5, which results in a very good electrical connection between the planar line 34 and the transition conductor 39.
- the horizontally aligned pin 19 can also be dispensed with.
- only one or more than two pins which can be inserted into the printed circuit board 5 can be provided on the line arm 13 or 14.
- several horizontally extending pins 19 resting on the planar line can also be provided.
- the horizontally oriented pin 19 can be angled forwards, as shown in FIGS. 3 and 4, or backwards relative to the line arm 13 or 14, as is shown, for example, in FIG.
- the line arm 14 initially runs from its end inserted into the circuit board 5 at an angle of approximately 45 ° to the circuit board level and then changes into a horizontal course.
- FIG. 3 or FIG. 4 gives a good adaptation of the transition line 14 to the planar line 34, 35 on the circuit board 5.
- other shapes for the transition lines 39 are also possible, as is also indicated, for example, in FIG.
- Improvements in the adaptation can be achieved by specifically dimensioning the width of the line arm 14 or its distance from the surface of the printed circuit board 5.
- the width of the line arm 13 or 14 can also change with increasing distance from the circuit board surface in order to achieve an improvement in the adaptation, as is shown, for example, in the exemplary embodiment in FIG. 2.
