Definitions
- the invention relates to a planar radiator with a Radiator level having surface resonators and a Coupling network having network level, the Area resonators with each other via the coupling network are coupled galvanically and in phase.
- the reception or the Radiation of directed electromagnetic radiation fields linear polarization in the microwave spectrum will be required today reflector antenna or planar antennas or radiators used.
- the radiation properties of the reflector antennas is based on the generation of a corresponding amplitude and Phase assignment of the electromagnetic Radiation field components on the reflector surface by means of suitable pathogen.
- the reflectors used are here either in the form of closed surfaces of defined curvature and border are designed or are latticed Arrangements of discrete conductive linear elements defined Length and spacing carried out.
- Known planar solutions are based on the arrangement of galvanically and parallel fed Area resonators of defined group size and spacing to each other.
- EP 0 200 819 describes a planar array antenna in Stripline technology known.
- the mechanical structure is there from a first substrate plate as a carrier for Antenna elements under the second substrate plate as a carrier for the couplers and the signal processing. Both substrate plates are connected by a thick metal plate, where the thickness of the metal plate is half Operating wavelength corresponds.
- a planar antenna is known from EP 0 383 292, in which Antenna elements on the ground surface of a two-sided coated circuit board are glued on which the Coupling network and additional electronics is located.
- the Antenna element consists of a surface resonator plate, which is applied to a dielectric substrate layer is.
- the substrate layer of the antenna element is made of "glass epoxy ".
- a planar antenna is known from WO 95/09455, which is also sandwich-like, and where the die Layer carrying antenna elements for manufacturing reasons two layers of the same material because the Antenna elements are capacitively coupled.
- a disadvantage of the known planar antennas is that mostly high system quality only in a small spectral range and therefore only with restrictions for use Suitable for multipoint multichannel communication services are, because of the small bandwidth, only relatively few Frequency bands can be transmitted with a single antenna.
- the planar emitter according to the invention advantageously only needs a common ground area for the emitter and network level, which significantly reduces the overall height of the emitter compared to known planar emitters and reduces the manufacturing material costs.
- the bandwidth of the radiation field to be transmitted and received by the radiator can also be varied without influencing the characteristic impedance of the coupling network by suitable choice of the thickness of the first dielectric layer, a high system quality being achieved in the entire spectral range at the same time. It is necessary for a planar radiator that the first layer is made of a material with the smallest possible dielectric constant ( ⁇ r ⁇ 1).
- the thin layer supporting the resonator surfaces can be manufactured from a heat-resistant material such as polyethylene terephthalate, on which the resonator surfaces can be applied permanently.
- the first layer can be made from an inexpensive foamed material. So that the planar radiator becomes flexible or pliable, the thickness of the first layer is greater than the thickness of the second layer.
- the first layer forms the actual base material of the planar emitter and essentially determines the properties of the emitter plane with its ⁇ r and loss angle tan ⁇ ⁇ .
- the material of the first layer is advantageously the cheap material polystyrene, which is flexible in its foamed form and in particular has a specific volume weight of 20kg / m 3 .
- the second layer is advantageously formed by a polyethylene terephthalate film which is glued to the first layer.
- the advantage of this polyethylene terephthalate film is that it forms a firm and permanent connection with copper, which means that the resonator surfaces have firm adhesion.
- Each surface resonator is electrical by means of an conductive connecting pin with the coupling network in electrically conductive connection, the electrically conductive Connecting pin in a perpendicular to the radiator and Through hole located at the network level.
- the connecting pins are relatively long, as a result of which the pins themselves have an electrically transforming effect.
- the inductive reactive component represented by the pen can therefore no longer be neglected and must be compensated for.
- This can be done on the one hand by means of a sleeve which at least in sections envelops the pin and is made of a material, in particular Teflon, which has a higher dielectric constant than the materials forming the dielectric layers, which serve as the base material for the radiator and network level.
- Teflon Teflon
- the electrically conductive thin Layer in the areas where the electrically conductive pins pass through the layer especially circular has window-like recesses, such that the pins with the electrically conductive layer not in electrical connection are.
- Form these circular window-like recesses Apertures, by means of the diameter of the recesses Coupling factor is adjustable.
- the coupling factor determines the portion of the signal intensity, which of the Radiator level is led to the network level.
- the optimal one Diameter of the orifices can be obtained by simulation or experimental tests.
- the surface resonators can be shaped and arranged as desired become. To generate the necessary impedance profile along the line of symmetry of the Area resonators, as well as to generate the necessary radiation-related individual characteristic of Area resonators it is recommended that Surface resonators to be rectangular, the Broadside is identical to the radiant edge.
- the Surface resonators are advantageously matrix-shaped arranged to each other. It has been shown that it is for most areas of application is sufficient, only eight Area resonators in particular in two lines and four Arrange columns. Also for the sake of simple Predictability and minimizing the dimensions of the planar emitter, it is advantageous if line and Column spacing of the matrix Area resonators are equal to each other.
- the planar has to enable components and plug-in systems Spotlights an extension that carries a wave path that a coupling point of the coupling network with a Connector connects.
- the connector is one commercially available N socket, which is modified in this way is that the inner conductor of the socket with the Microstrip line on the extension of the dielectric carrier of the coupling network is applied, is connected, and that the ground plane of the extension, the at the same time the extension of the electrically conductive layer is, with the outer surface of the socket by means of of a dielectric press block generated press pressure is.

- the thickness D2 of the layer 5 essentially determines that Total height of the planar emitter.
- the ground surface 6 has in the areas in which the pin 9th a circular one passes through the ground surface 6 Recess 10, the diameter of which is larger than that Outside diameter of the pin 9. Is the length of the sleeve 11 equal to the lengths D2 plus D3, the diameter is the Recess 10 at least as large as the outer diameter of the To choose sleeve 11.
- Layer 5 is made of polysterol, which is foamed in State is flexible, which makes the planar emitter in certain Is flexible. This bendability is only marginal through the thin copper layers 4, 6 and 8 and the layer 7 impaired.
- the coupling point 12 not be arranged centrally to the resonator surfaces 4. With the help of known simulation methods, it can be used for frequency and bandwidth required Calculate the input impedance of the surface resonators, from which the Location of the coupling point 12 can be derived.
