Definitions
- the invention relates to a planar radiator with a radiator plane having surface resonators and a network plane with a coupling network, the surface resonators being galvanically and in phase coupling with one another via the coupling network.
- planar antennas usually only have high system quality in a small spectral range and are therefore only suitable for use with multipom multichannel communication services to a limited extent, since the small bandwidth means that only relatively few frequency scanners can be transmitted with a single antenna are.
- planar radiator is constructed in a sandwich-like manner from layers which are plane-parallel to one another, and in that a first dielectric layer by means of an electrically conductive thin layer, which forms the common ground plane for the radiator and network levels, of a second dielectric layer is separated, and that the first dielectric layer on its side facing away from the electrically conductive layer carries the surface resonators, and that the second dielectric layer carries on its side facing away from the electrically conductive layer the coupling network which is formed from microstrip lines.
- the planar emitter according to the invention advantageously only needs a common ground area for the emitter and network level, as a result of which the overall height of the emitter is significantly reduced compared to known planar emitters and the manufacturing material costs are reduced.
- Kar.r. without influencing the wave resistance of the coupling network, by appropriately selecting the thickness of the first dielectric layer, the band width of the radiation field to be determined and err.ofa ⁇ enen radiation field can be varied, wooei at the same time a high system quality is achieved in the entire spectral range.
- Each flat resonator is open to the coupling network with an electrically conductive connection by means of an electrically connecting pin,
- the electrically conductive connector pin is inserted in a through hole perpendicular to the emitter and network veins.
- the connecting pins are relatively long, as a result of which the pins themselves have an electrically transforming effect.
- the inductive flower component represented by the pen can therefore no longer be neglected and must be balanced.
- 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 number than the materials forming the dielectric layers, which serve as the base material for the emitter and network level.
- Teflon Teflon
- the inductive dummy component of the pin can also advantageously be compensated for by means of the coupling network, by utilizing the transforming effect of the length and width ratios of the microstrip lines used.
- Such transformations using microstrip conductors are well known from the relevant literature.
- a pulse can optionally be omitted.
- Apertures are obtained by simulation or experimental tests.
- the first dielectric layer is constructed from two dielectric materials, each of which forms a layer for itself.
- the thickness of the first layer is greater than the thickness of the second layer, the second layer bearing the resonator surfaces on its side facing away from the first layer.
- the first layer forms the actual 3as ⁇ 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.
- the fan resonators can be shaped and arranged in any way. To generate the necessary impedance profile along the line of symmetry of the cavity resonators, which is transverse to the radiating edge, and to generate the necessary straniun ⁇ soezc ⁇ enen individual characteristic of the cavity resonators it is recommended to design the Fiachenresonatoren recntec ⁇ g, whereby the broad side is identical to the radiating edge.
- the cavity resonators are advantageously arranged in a matrix to one another. It has never been shown that for most fields of application it is sufficient to arrange only eight fan resonators, in particular two rows and four columns. Also for reasons of simple computability and minimizing the dimensions of the planar emitter, it is advantageous if the row and column spacings of the array resonators arranged in the form of a matrix are identical to one another.
- the planar radiator has an extension that carries a wave path that connects a coupling point of the coupling network to a connector.
- a commercially available N socket can be connected, which is modified such that the inner conductor of the socket is connected to the microstrip line, which is applied to the extension of the dielectric carrier of the coupling network, and that the ground area of the extension, which at the same time Extension of the electrically suffering layer is flatly connected to the outer jacket of the socket by the pressing pressure generated by means of a dielectric press block.
- the wave path is formed by a microstrip line, the second dielectric layer and the ground plane, which is connected to the coaxial connector accordingly.
