  Accordingly, the problem of the present invention is to provide a novel material that is configured to be significantly smaller than known antennas and thus facilitates attachment to other portable devices, thereby providing additional material detection by these devices. Is to provide an antenna array.

  The object is achieved according to the invention by an antenna arrangement having the features of the independent claims. Additional advantageous embodiments can be taken from the dependent claims.

  According to the invention, the antenna arrangement has at least two magnetic rings with a rectangular ring cross section, the magnetic rings being arranged on the printed circuit board spaced from each other by spacers. The rectangular ring cross section forms magnetic ring side surfaces with opposite polarities, the opposite polarities of the magnetic ring surfaces are oriented towards each other, and the central hole of the magnetic ring penetrates through the hole in the spacer A hole is formed. Thus, the magnetic ring can be placed on both sides of the printed circuit board, so that the printed circuit board is used as a spacer, providing two magnetic rings and a through hole through the printed circuit board. As such, it has a hole. Another option is to place the magnetic ring on one side of the printed circuit board with a spacer with a through hole so that the through hole formed by the magnetic ring and the spacer is relative to the printed circuit board. It extends vertically or substantially parallel. In principle, additional magnetic rings separated by spacers can be adjacent to each magnetic ring, and the magnetic rings are oriented such that magnetic ring surfaces with opposite polarities face each other.

  The antenna formed by the magnetic ring and the spacer is connected to an electronic circuit, and when a sawtooth voltage including a pause is applied, oxygen or nitrogen ions are generated from the air around the magnetic ring and inside the magnetic ring. . The ions are accelerated by the magnetic ring and the spacer disposed between the magnetic rings, and emitted from the through hole. The multiple offset magnetic rings provide higher rate cations until a resonant avalanche corresponding to the ionization energy step is generated. This produces a positive ion beam in the S-Pole direction for oxygen and nitrogen cations, and conversely an anion beam for oxygen and nitrogen anions. Generally, it is an acceleration path for oxygen and nitrogen ions. Since cations are smaller and lighter, they are accelerated more strongly and therefore have higher material permeability, so that the cations have little or no collision with air molecules. Thus, cations are advantageously utilized. Depending on the frequency and amplitude of the triangular wave signal, each cation is adjusted to the material to be detected. In practice, most oxygen cations are utilized. This is because oxygen cations are ionized more rapidly from air with a smaller binding force. When the oxygen cation impinges on each cation in a given material, a reflection is provided that can be measured and processed in the transmission brake as an electrical signal in the electronic circuit as it returns to the magnet. The display is provided optically and acoustically. The magnetic ring arrangement acts like an ion source in accelerating cations and anions. By using a differential amplifier in the electronic circuit, the interference signal is suppressed in a known manner.

  In this part according to an advantageous embodiment of the invention, the holes in the spacers are aligned with the holes of the magnetic ring in order to form the through space as advantageously as possible to form and accelerate ions, in particular cations. Yes.

  According to a particularly preferred embodiment of the invention, the spacers for the first and second magnetic rings are printed circuit boards, so that at least one of the magnetic rings is each of the printed circuit boards in a space-saving manner. The printed circuit board has a through hole. As mentioned above, this arrangement can be extended by additional spacers and magnetic rings.

  According to another advantageous embodiment, the circuit is arranged on a printed circuit board, the circuit emits a sawtooth or triangular wave signal through a magnetic ring, and the cycle of the sawtooth signal has a transmission pause. And the circuit receives the return signal in a transmit pause.

  Thus, the antenna arrangement according to the present invention facilitates transmitting and receiving and processing ion beams in a minimal space. If the entire unit is correspondingly configured with an antenna array, the through-holes can be used simultaneously to determine the direction of the material to be searched for, for example by a laser pointer beam or a laser diode beam. For inaccessible locations, such as medical technology, a lightwave conductor (1 mm in diameter) can be inserted into the through-hole, thereby receiving information from another end of the lightwave conductor. Due to its small dimensions, the antenna array can also be incorporated into a mobile phone, thereby providing material detection by the mobile phone.

  Other features of the present invention can be understood from the claims, the detailed description and the following description of the embodiments in combination with the accompanying drawings. Individual features may be implemented individually or in groups when practicing the present invention. The invention will be described in the following on the basis of advantageous embodiments with reference to the drawings.

FIG. 2 is a schematic cross-sectional view of an antenna arrangement in which a printed circuit board is used as a spacer between two magnetic rings. FIG. 3 shows an antenna arrangement comprising two magnetic rings with through holes arranged substantially parallel to the printed circuit board and a spacer arranged between the magnetic rings. It is a figure which shows the printed circuit board for controlling an antenna.

  FIG. 1 shows an antenna 1 with a magnetic ring 3 and a magnetic ring 4 attached to both sides of a printed circuit board 2 by holders 2 ′. The magnetic ring has a cross section that is also rectangular, i.e. square. The magnetic ring side surfaces 3 'and 4' act as N extremes, and the magnetic ring side surfaces 3 "and 4" act as S poles. The holes 5 and 6 of the magnetic rings 3 and 4 are aligned with the holes 7 of the printed circuit board 2 and form continuous holes. The printed circuit board 2 is used as a spacer between the two magnetic rings 3 and 4. The magnetic rings 3 and 4 are arranged so that the opposite polarities are oriented towards each other. The two magnetic rings 3 and 4 each form an electrode. The electrodes are separately connected to electronic circuits arranged on the printed circuit board 2. The electronic circuit is not shown. An arrow 8 indicates the direction in which oxygen and nitrogen cations exit as a cation beam from the internal space formed by the holes 5 and 6 and the through-hole 7. The selective anion beam moves in the opposite direction.

  FIG. 2 shows a similar arrangement, where like components are indicated with like reference numerals. In this arrangement, both magnetic rings 3 and 4 are arranged on one side of the printed circuit board 2. Between the two magnetic rings 3 and 4, a spacer element 9 configured as a spacer having a through hole 7 is provided. The through holes 7 are aligned with the holes 5 and 6 in the respective magnetic rings 3 and 4. In other words, the N pole is arranged on the right side, whereby the cation beam formed from oxygen and / or nitrogen cations moves in the direction of arrow 8.

  The antenna with two magnetic rings shown in FIGS. 1 and 2 has neodymium as a magnetic ring material in one embodiment. The magnetic rings 3 and 4 have a magnetic strength of 250 to 300 mT. The spacer 9 and the printed circuit board 2 have a thickness of 1.5 to 5 mm. The height of the magnetic rings 3 and 4 may be 2 to 20 mm, the outer diameter may be 6 to 50 mm, and the inner diameter may be 2 to 10 mm. The antenna can be extended by additional spacers 9 and magnetic rings 3.

  FIG. 3 shows a block diagram of an antenna circuit comprising a triangle generator 10 in which the magnetic rings 3 or 4 are connected in parallel via amplifiers 11 and 12. A differential amplifier 13 is connected between the magnetic rings 3 and 4, and the differential amplifier passes the obtained signal via an analog-to-digital converter 14 to an optical and / or in particular acoustic display device. Send. A connectable resistor is provided between the amplifier 12 and the triangle generator 10. In the antenna circuit diagram, resistor R1 is connected in series with amplifier 12, parallel resistors R2 and R3 are connected between resistor and amplifier 12, and capacitor C1 is for changing voltage. A typical voltage divider circuit is formed.

  The triangle generator generates a known triangle wave or sawtooth signal with rising and falling flank and a pause between the next triangular wave signal. Both magnetic rings 3 and 4 are, in one embodiment, applied with a sawtooth voltage of 70 mV amplitude at a frequency of 149.00 Hz of the sawtooth voltage and a pause of 50% of the period. This frequency can be used to detect pure water. Due to the voltage applied to the magnetic rings 3 and 4, oxygen and nitrogen cations and anions are separated from the air surrounding the magnetic rings 3 and 4 and placed inside the magnetic ring. Cations and anions are accelerated by the array described above and released from the array. As described above, the arrow 8 indicates the direction of the cation. Cations are more quickly accelerated than anions that pass through the material easily due to their small dimensions and are moved in the opposite direction. When the cation collides with pure water as in this embodiment, the cation is reflected. Otherwise, the cation passes through the material. The returning cations can then be detected in a signal pause. This detection is done electronically, and it is very advantageous to make the measurement after a measurement process using a headset to detect in which direction the return signal occurs. The antenna array according to the present invention described above is attached to a material detection device, for example. Material detection devices are commercially available from AMPASSMETER GmbH, and with this material detection device this type of measurement can be performed to find materials. The detection of different materials takes place at different frequencies accessible to the user of this type of unit. The material detection by the material detection device is possible over a distance of 1 to 2 kilometers.
