Definitions
- the invention relates to an antenna according to the preamble of claim 1.
- Such an antenna is for receiving satellite navigation information from US 6,098,547 A in the form of a transverse to the system axis in the front Field of an artillery detonator-held dielectric disc known coated on both sides and for inductive adjustment of their resonance frequency with axially parallel, electrically conductive entrances between the two sides Metallizations is equipped.
- the present invention lies in the knowledge of the circumstances described above based on the technical problem, one with regard to its mechanical and electrical properties for simple, even subsequent application High-frequency antenna suitable for rolling artillery ammunition in particular for satellite communications including navigation and telemetry to create in the L and S bands.
- the slot antenna integrated into the ammunition body ogive with its removable detonator and so it can easily be applied to the ammunition afterwards.
- the axial position of the antenna depends on the frequency-dependent Diameter and is therefore further for the reception of navigation satellites to the basis, for higher-frequency telemetry communication on the other hand Tip of the detonator shifted.
- the outer opening of the slot is radial directly behind a slot running around the surface of the igniter.
- An axially symmetrical toroidal antenna characteristic then extends along this, so that despite the rotation around the longitudinal axis of the ammunition always a segment of practically constant sensitivity across the half space the horizon, without it being more complex in terms of circuitry and possibly electrically disruptive switching processes as in the case of the tracked Antenna characteristics according to EP 0 840 393 A2 are required.
- the antenna is again designed as a disk-shaped but now extremely resistant to acceleration Sandwich structure made of metal turned parts with one to the taper axis concentric resonator annulus, which is a cylindrical reflector wall opposite with the radially circumferential emitter slot in the conical surface of the detonator opens.
- the annulus is transverse in its center or symmetry plane divided to the longitudinal axis, around a ring disk made of electrical as bad as possible to be able to insert conductive material of increased dielectric constant independent of low dielectric losses and high tracking resistance characterized by frequency and temperature, like the fluorine-containing polymer PTFE (polytetrafluoroethylene) sold under trade names such as Teflon, Fluon or Hostaflon is on the market.
- PTFE polytetrafluoroethylene
- Ring disc By choosing the material and dimension Ring disc can be specified according to the geometric dimensions of the Subsequent annulus an electrical resonance fine tuning without further ado on e.g. make a certain satellite frequency.
- an electrical resonance fine tuning without further ado on e.g. make a certain satellite frequency.
- the circumferential circumferential one Antenna slot filled dielectric namely through an outside on the Washer flange-like circumferential, radial to the surface of the igniter cone extending collar.
- the antenna is connected via a two-wire, at least two axially opposite positions of the inner edges of the slot connected Antenna cable.
- the antenna is connected via a two-wire, at least two axially opposite positions of the inner edges of the slot connected Antenna cable.
- the invention provides an easily tunable, mechanically extreme loadable slot antenna for the detonator of artillery ammunition a sandwich construction, in which one between an upper and a lower dimensionally stable profiled metallic cover washer axially enclosed, axially divided resonator annulus is equipped with a dielectric washer, with a circumferential collar around the central cylindrical reflector wall radially opposite through an axial slot between the two hollow cylindrical External walls of the annulus through to the outer surface of the circumferentially slotted detonator jacket extends.
- One of the two Cover disks are the inner edge of the antenna slot opening into the annular space by a tire that can be inserted into the forehead of the outer wall defined, at the circumferentially offset connection points through the dielectric washer and the axially opposite cover washer are contacted through to a circuit carrier disc, whereupon they by means of of a matching network merged in a single phase onto an antenna line are, whose second phase is directly connected to the adjacent cover plate is.
- the head igniter 11 shown in view in FIG. 1 is intended for using a not shown thread in front of the conically tapered front of a spin-stabilized or aerodynamically stabilized artillery ammunition screwed shut become. It is radially all around with a slightly spherical cone wall 12 penetrating antenna slot 13 designed with dielectric material is filled, which with the axially on both sides adjoining outer surface of the Wall 12 is flush.
- antenna slot 13 designed with dielectric material is filled, which with the axially on both sides adjoining outer surface of the Wall 12 is flush.
- In front of the radial plane of the slot 13, that is to say The tip of the fuse front part 15 is located there are mechanical or Electromechanical fuse and trigger devices of the igniter 11 and possibly aerodynamically acting braking devices for shortening the trajectory, as in the own older application DE 199 57 363 dated 29.11.99 described in more detail.
- the front part 15 and the rear part 16 are underneath coaxial intermediate layer of the mechanically extremely heavy-duty antenna 17 by means of the antenna 17 running parallel to the longitudinal axis 18 of the igniter through extending clamping screws 19 interconnected.
- a flexible one Antenna line 20 with coaxial cross section leads to the rear part of the igniter 16 located antenna amplifier (not shown in the drawing).
- the receiver or transmitter signal processing circuit which like their power supply unit 22 (for example in the form of an activatable battery or an inflow generator) is installed in the area of the base of the detonator rear part 16.
- FIG. 3 shows that and how the disc-shaped Antenna 17 is made of torsionally rigid components sandwiched. It essentially consists of two mechanically stiff metal Cover disks, namely a plate-like towards the front part 15 of the fuse flat cup-shaped rotationally symmetrical profiled metal top plate 23 and one also oriented in the opposite direction to the detonator rear part 16 plate-like flat pot-shaped - but in this example case for handling reasons for connecting the antenna cable in two parts - rotationally symmetrical profiled metal washer 24. Each of these two washers 23-24 has a central stiffener in the form of a pot bottom 26 between the Walls 24 and 31 coaxially excellent base 25.
- this annular space 28 is thus axially divided, it can be placed in it before it is placed insert an annular disk 29 made of dielectric material into the upper disk 23.
- The has an externally radially circumferential, flange-like projecting collar 30 from compared to the washer 29 of significantly lower axial strength.
- the collar 30 extends radially with respect to the longitudinal axis 18 through the slot 13 ', which due to the axial height of the base 25 between each other facing end faces of the walls 27 enclosing the annular space 28 on the outside and 31 remains.
- the collar 30 preferably projects even radially through the Slot 13 'into the slot 13 in the wall 12 between the front part of the igniter 15 and detonator rear part 16 until it is flush with the immediately adjacent outer surface. This makes assembly easier axial assembly of the front and rear of the igniter 15-16 via the antenna 17 and avoids eddies in the area of fluid dynamics particularly sensitive ogive of the ammunition body.
- the antenna 17 is covered with a dielectric disk 32.
- This serves as a wiring support for a link network between four to each other orthogonal connections to the inside, towards the annular space 28 towards the end of the Antenna slot 13 '.
- an imaginary on the disc 32 at the corners Squares four coaxial conductor pieces 33 parallel to the system longitudinal axis 18 anchored.
- the inner conductors reach through the washer 29 in order to finally to end a narrow electrically conductive tire 35.
- the outer conductors are with the top plate 23 and with the underside of the circuit carrier plate 32 conductive connected.
- the antenna 17 is coaxial between the antenna washer by means of screws 38 24 and top plate 23 with the interposition of the hollow cylindrical Walls 26, 31 radially penetrating collar 30 axially with each other tense and therefore additionally torsion-resistant.
