B. at holes in a wall of the objects included therein - z. B. steel reinforcements, power cables, water pipes and the like - are safe from being damaged, should the craftsman precise information about a place, that is, the travel position on the wall surface and the depth in the wall of the enclosed object to be conveyed. A radar device is, as described in WO 96/19737, usually from a "front end" - that is a transmitting and receiving unit - and a display device The system disclosed in WO 96/19737 front end has, as explained at the beginning, a shielded. space for electrical circuits and two adjoining this space areas, which are designed as transmitting antenna and receiving antenna. the cavities for the transmitting and the receiving antenna in the form of horns, in which radiating elements (eg., in the form of wires) are installed. the screening of the circuitry accommodating space is done on one hand by the circuit board for the circuits be translated housing and on the other hand by the walls of the antenna horns which are fixed on the opposite the circuitry side of the printed circuit board. the document WO 96/19737 to be extracted embodiment of the front end of a radar apparatus has been designed in relati v-consuming, because it consists of a variety of items.

From Scripture by M. Herscovici, "New Considerations in the Design of Microstrip Antennas", IEEE Transactions on Antennas and Propagation, Vol 46, No. 6, June 1998, pages 807 -. 812, a transition line as an electrical connection between a planar antenna and a planar line known to a printed circuit board. the planar antenna at M. Herscovici is arranged at a certain distance above the circuit board and consists of a serving as the radiating element conductive plate (patch) of the edge of the transition line to a planar line on the circuit board leads. the line arm of the transfer pipe may be integrally connected to the radiating element of the antenna. the other end of Leitungsarms, referred to in the document as a 3D transition, has at its resting on the printed circuit board end of a contact foot on, for example, with the planar line can be soldered. the surface mounted on the circuit board contact pad is not able to give the transition line is a high mechanical stability. In particular, this transfer line is not possible because the described in the document type of fixing and contacting on the circuit board in a position to hold a planar antenna connected to it with a sufficiently high stability. Therefore, an additional supporting posts required for the planar antenna.

The invention is based on the object to provide a radar apparatus of the aforementioned type which is compact in design and manufacturing technology as simple as possible, but to realize specifically the antenna element with high stability, with good electrical transmission characteristics are desired.

Advantages of the Invention

Said object is achieved in that a single housing is provided which constitutes both a shielded space for circuits as well as at least one cavity for at least one antenna radiating element. A shielding partition wall between two spaces is formed by a printed circuit board carrying on one side of the electrical circuits and the antenna array is installed on the other side thereof. For the assembly of the front end of a radar apparatus can only needs a circuit board on which electrical circuits and at least one radiating element of an antenna array are pre-installed, to be inserted into a housing. The 'inventive features not only lead to a manufacturing simplification, but also to material saving, because the electrical circuits and the antenna array are placed in a common housing and separate housing arrangements for electrical circuits and the antenna assembly superfluous.

Advantageous developments of the invention will become apparent from the dependent claims. Conveniently, is formed a shoulder on the housing, which serves as a support and for securing the printed circuit board.

The housing advantageously has on the side remote from the circuit board side of the at least one antenna cavity at least one off or inlet opening for radar beams, and this opening is closed with a continuous for the radar beams dielectric plate.

Production engineering advantages it brings when the housing is formed in one piece, wherein the housing is made of either metal or of a metallized plastic.

The electromagnetic shield between the two rooms can be realized in a simple manner by a metallized layer on or in the circuit board.

An easily manufactured antenna element is preferably made of a sheet formed with an aligned approximately parallel to the printed circuit board section, sheet metal segments are angled away from the opposing two edges, as duct arms for coupling the radiating element to a feed network on the circuit board, and as a spacer for the planar portion serve on the board.

To give the radiating element in its cavity a better grip, it is expedient to arrange a plurality of resilient tongues at the edges of the planar portion of the radiating element or, the covering as supports for the radiating element relative to a this, serve for radar beams continuous dielectric plate. The duct arms for coupling the radiating element to a feed network on the circuit board advantageously have at its contactable with the circuit board end of one or more pins, which are oriented substantially perpendicular to the circuit board plane, and in present therein openings and with insertable the planar line are contacted. By insertable into openings of the printed circuit board pins of the line arm receives a very high mechanical stability. In addition, the pins in the openings can be simple in process engineering solder, so that thereby a permanent, little susceptible to malfunction contact between the transition duct and a planar line on the circuit board can be produced.

An improvement of the electrical contact between the transition duct and the planar line, and also the mechanical stability of the transition duct can be achieved in that at least one other outgoing from the line arm pin is provided, which relative to the other (s) pin (s) is angled at right angles, so that it places at the onset of Leitungsarms in the printed circuit board to a conductive trace of the planar line and thus be contacted. Advantageously, a further towards them perpendicularly angled pin are provided in openings of the printed circuit board pins and insertable between these two at the two line arm ..

The transition duct, consisting of the line arm and the contact means can be formed as a one-piece, preferably made of a sheet metal part.

The transition circuit according to the invention can be advantageously used for an electric and mechanical connection between a circuit board and a spaced-apart above the circuit board planar antenna use.

Description of an embodiment

1 shows a longitudinal section through a so-called front end of a radar apparatus, which is provided for detecting enclosed in a wall objects. If in the application of wall inclusions mentioned which are to be tracked by radar so that the application of the radar is not limited to walls, but also extends to similar areas such. As ceilings or floors. In addition to the front end, a radar device has usually also a display part may be displayed on the location information on a tracked object in a wall. is here not be discussed on the display unit, as it is beyond the scope of the invention. With a front end part of the one device is meant in which all transmit and

Receiving means are accommodated. Also circuits such. As digital signal processors for processing the received signals may be arranged in the front end; but they can also be accommodated in a separate apparatus part.

The front end of the radar apparatus comprises a housing 1, in which all belong to the front-end parts are housed together. The front end consists of two main groups of components. The first group of components are electrical circuits for processing high frequency signals or low-frequency signals or digital signals. The second assembly of the front end consists of a transmitting and receiving antenna array. These two different modules are accommodated in separate and shielded against electromagnetic radiation rooms 2 and 3 of the housing. 1 The housing 1 is shaped so that the two spaces 2 and 3 are superposed. In the upper space 2, the electrical circuits 4 are accommodated, said circuits 4 are arranged on a circuit board. 5 This printed circuit board 5 is fixed at its edges in the housing 1 and provides a relative electromagnetic radiation-shielding partition wall of the chamber 2 relative to the underlying circuit board 5 space 3. In order to ensure an electromagnetic shielding of the space 2 with respect to the space 3, the circuit board 5 is provided with one or more metallized layers. This at least one metallized layer can either be externally applied to the circuit board or inside the circuit board extend. 5 In the example shown in the Figure 1 embodiment, such a shielding metallic layer 6 is disposed inside the circuit board. 5

A simple way of fixing the printed circuit board 5 in the housing 1 provides the fact that to the housing 1 a circumferential shoulder is formed. 7 By this shoulder 7, the housing 1 is, as the longitudinal section shown in Figure 1 illustrates a stepped shape. The expansions of the two superposed chambers 2 and 3 are therefore different in size. On the shoulder 7 of the edge of the printed circuit board 5 is located and can there by fasteners (eg. As screws, rivets) 8, 9, or by soldering or gluing or other suitable fixing means are fastened.

The cavity 3 beneath the circuit board 5 located serves as transmitting and receiving antenna. A belonging to the transmitting and receiving antenna radiating element 10 is located in the cavity 3 and is fixed to the electric circuits 4 opposite side of the printed circuit board 5 is contacted with a non-illustrated feed network electrically. The feed network in the simplest case, for. As of a

via which an electrical connection between the antenna and transmitter and receiver circuits is prepared microstrip fork. In the illustrated embodiment is an antenna with a single antenna element 10 that emits both radar beams as well as receives. Deviating from a transmitting and a receiving antenna can be designed separately. Then, the cavity would be divided into two compartments 3, each of which would be equipped with a separate radiator element. The housing 1 is at the lower side, where the radar beams enter and leave open. This opening is closed with a continuous for the radar beams dielectric plate 11, which has the function of a radome. If the transmitting antenna and the receiving antenna would be located separated from each other in adjacent cavities, each of these adjacent compartments will be provided with an opening which suitably would be sealed with a dielectric plate. The connection of the housing 1 with the dielectric plate 11 can be realized in very different ways. Connecting means for can. As screws, rivets, glue, solder or the like. Also, additional to the housing 1 means for fixing the dielectric plate 1 can be formed.

2 shows a specific embodiment of a radiating element 10 is shown in perspective beneath the circuit board. 5 The radiating element 10 consists of a 12 approximately parallel to the printed circuit board 5 aligned planar portion The flat portion 12 may be a rectangular shape (as shown in Figure 2) have; but it can also have a round, oval or similar shape. In order to achieve the lowest possible production expense, the radiating element is preferably manufactured as a sheet metal stamping.

two sheet metal segments are angled 13 and 14 on two opposite edges of the flat portion 12 serving as a duct arms for coupling the radiating element 10 to a not shown feed network on the circuit board 5, and as a spacer for the planar section 12 above the circuit board. 5 The bent ends of the metal segments 13 and 14 serve for resting on the printed circuit board 5. At the ends of the bent sheet metal segments

13 and 14 are present contact pins 15, 16, which can be contacted in corresponding openings 17, 18 in the circuit board 5 and inserted therein to corresponding circuit traces of the feed network.

Through this type of connection between the radiating element 10 and the circuit board 5 is not only an electrical contact to a feed network is produced, but the radiating element 10 is also mounted on the underside of the circuit board. 5 In addition to the contact pins 15 and 16, an additional solder tail can be provided at the ends of the metal segments 13 and 14, 19 (at the end of the sheet metal segment 13 see) that can be soldered to a conductor track on the underside of the circuit board. 5

By acting as a spacer sheet metal segments 13 and

14, the flat portion 12 is held of the beam member 10 at a certain distance over which a feed network circuit board carrying. 5 Thus located between the planar portion 12 and the circuit board 5, a dielectric having a very low permittivity, namely air, whereby a very wide-band operation of the antenna becomes possible.

An optimization of the bandwidth of the antenna can be effected that, as the figure 2 it can be seen, the flat portion 12 has tongue-like addition to the conduit arms 13 and 14 are extensions 20 to 27. In the illustrated embodiment, are two extensions 20, 24; 21, 25; 22, 26; 23, 27 arranged side by side. With the two adjacent extensions to improve the matching of the antenna is effected in the direction of lower frequency ranges. Deviating from the illustrated embodiment can also laterally from the conduit arms 13 and 14 are just an extension 20, 21, 22, are provided 23rd They also cause the bandwidth of the antenna improving adaptation alone. If not a very broadband operation of the antenna is required, can also be dispensed to all extensions.

The figure 2 shows that at each corner of the flat portion 12 one of the extensions 24, 25, 26, 27 is bent over the flat portion 12th These bent-out extensions 24, 25, 26, 27, which act as resilient tongues, supporting the radiator element 10 relative to the dielectric plate 11 beneath it (see Figure 1). This gives the radiator element 10 in the cavity 3 a defined stable position, so that a possible oblique position of the radiating element in the housing 1 as such. As may arise due to mounting tolerances or inaccuracy in the assembly is balanced.

The housing 1 may be made of a punched and bent sheet metal; but it can also be manufactured in die casting or injection molding. Either the material is made from pure metal or of a metallized plastic. To the housing 1 Plug elements or other parts required for the complete installation of the radar, for example, still be formed with.

In the figure 3 a section of a multilayer printed circuit board 5 is illustrated. To make the different layers of printed circuit board 5 clear the board is drawn in an exploded view of the 5th The printed circuit board 5 shown example, consists of two dielectric layers 30 and 32. On top of the first dielectric layer 30, an inner conductor 34 and an outer conductor 35 of a coplanar line is applied. The outer conductor 35 of the coplanar line is usually at ground potential. Between the two

Dielectric layers 30 and 32 is further also at ground potential conducting layer 6. This layer 6 comprises directly below the lie on the opposite side of the first dielectric layer 30 inner conductor 34 a recess 37. Between the two dielectric layers 30 and 32 existing conductive layer 6 is electrically connected through a plurality introduced into the dielectric layer 30 via holes 38 to the outer conductor 35 of the coplanar line.

Notwithstanding 5 also has a more than two-layer printed circuit board or even a single-layer printed circuit board in connection with the detail further below-described transition line may be used from that illustrated in the Figure 3 embodiment, a circuit board. Also, the shown in the Figure 3 planar line type, namely the coplanar line, not a prerequisite for the use of Übergangslei ung. For the use of transition duct described below, any type comes from running on a circuit board planar line (for example microstrip line, slot line and the like) in question.

In the figure 3 35 a transition line is in an exploded view above the planar line 34 shown. 39 The specific object of this transition duct 39 is that it establishes an electrical connection, in particular for high frequency signals between the planar line 34, 35 on the circuit board 5 and a circuit part, the radiating element (patch) 10 of a planar antenna. The radiating element 10 is disposed at a distance above the printed circuit board 5 as the antenna for its broadband operation, the air dielectric between the printed circuit board 5 and its radiating element (patch) is required 10th

The transition line 39 consists of a from the plane of the circuit board 5 out curved line arm 14. The line arm 14 is connected at its projecting beyond the printed circuit board 5 with the end of radiating element 10 degrees. At its planar with the line 34 to be contacted end, the line arm 14 three pins 16,19. Two pins 16 are oriented perpendicularly to the printed circuit board. 5 On the other hand, is oriented parallel to the plane of the printed circuit board 5, the third pin 19 which is located preferably between the two oriented perpendicularly to the printed circuit board 5 pins 16, that is angled perpendicular to the other two pins sixteenth For the two vertically aligned to the PCB 5 of the pins 16 Leitungsarms 14 30 and 33 openings 36, 361 and 40, 42 are present in the dielectric layers, wherein the pins can be plugged in the Leitungsarms 14 16th Also, the coplanar line on the dielectric layer 30 recesses 44 and 46 are present in the inner conductor 34, through which the pins of the dielectric layers 30 and 32 can penetrate into the openings 16 36,361,40 and 42nd

The radiating element 10 has, as is seen for example in Figure 2, two transition lines 39, which ensure via the conduit arms 13 and 14, a mechanical and electrical connection of the radiating element with the printed circuit board 5 of the arrangement.

The cross-section shown in the Figure 4 by the printed circuit board 5 shows an inserted therein transition line 39 and a pin 16 on the line arm 14 which penetrates the inner conductor 34 of the coaxial line, the dielectric layers 30 and 32 and the intermediate conductive layer. 6 In this illustration, the figure 4 it is also clear that the third, horizontally extending pin 19 rests on the inner conductor of the coplanar line 34 when the line arm is inserted into the circuit board 5 fourteenth After the transfer line is inserted into the circuit board 5 and 39, the pins 16,19 are soldered to the inner conductor 34th In the figure 4, the remaining after the soldering process solder 43 is indicated. The openings 36,361,40 and 42 in the dielectric layers 30 and 32 can be contacted by the inner conductor 34 on the upper side of the printed circuit board 5, thus resulting in a very good electrical connection between the planar line 34 and the transition conductor 39 is established.

For the electrical connection between the conduit arms 13 and 14 of the transition lines 39 and the planar line 34, 35 can also be dispensed on the horizontally oriented pin 19th Derogation 13 and 14 are on line arm either only one or more than two are provided in the circuit board 5 insertable pins of the illustrated embodiment. Similarly, a plurality of horizontally extending, planar resting on the lead pins 19 may be provided. Depending on the course of the planar direction of the horizontally aligned pin 19 can forward, as shown in Figures 3 and 4, or be angled rearwardly relative to the line arm 13 and 14, as shown for example in FIG. 2

Such as in particular the side view of a transfer line can be seen in Figure 4 39, the line arm first 14 extends from its inserted into the printed circuit board 5 end thereof at an angle of approximately 45 ° to the circuit board plane and then merges into a horizontal course. With this form of Leitungsarms 14 of the embodiment according to Figure 3 and Figure 4 gives a good adaptation of the transition line 14 of the planar line 34, but 35 5 on the circuit board Other shapes for the Übergangs1eitungen 39 are also possible, as shown for example in the figure 2 is indicated.

Improvements in the adjustment can be achieved over a specific dimensioning of the width of the Leitungsarms 14 and its distance from the surface of the circuit board. 5 Also, the width of the Leitungsarms can 13 and 14 change with increasing distance from the circuit board surface, in order to achieve an improvement in the adjustment, as shown for example in the embodiment of FIG. 2

The transition lines 39 consisting of the conduit arms 13 and 14 and the pins 15,16 and 19 is preferably a one-piece part. It can be, for example, punched out of a sheet and taken by bending in its final form. The Übergangslei clothes can be produced as an integral cast or pressed part. The transition line 39 is either made entirely of a conductive metal or of a plastic material which is coated with a conductive layer.
