The utility model is characterized in that a rectangle patch is arranged in parallel above a horizontal bending segment of the 'L'-shaped probe, a distance kept by the both is an S, a vertical distance between the rectangle patch and the grounding plate is H, and the horizontal bending segment of the 'L'-shaped probe is connected to an internal conductor of the coaxial joint in an N shape through the transmission wire. The utility model has the advantages of convenient fabrication and low cost, the aspects of frequency bandwidth and gains are fundamentally improved, and the structure can also be used for a radiation mode of circular polarisation.
Description
The utility model belongs to microwave transmission, microwave antenna technical field, specially refers to the paster antenna of a kind of " L " shape probe feed.
The quality of microwave antenna performance, for microwave transmission system extremely important influence is arranged, it directly has influence on the bandwidth of microwave transmission system, gain and efficient, in the antenna applications of reality, usually all required wide band performance, in prior art, major defect with paster antenna of traditional form is its narrow-band characteristic, for its frequency band of broadening, in some disclosed documents several technology have been proposed, as " double-deck electric coupling rectangular patch antenna " (Characteristics ofa two-layer electromagnetically Coupled naetangular patch antena " Electran Lett; Vol.23 PP1070-1072; 1987); propose to add the example that parasitic patch is come its frequency band of broadening in the literary composition; " thick rectangular microstrip antenna experiment and research " (" Experimental investigation of electrically thick nectangularmicrostrip antennas " IEEE Trans.Antemas Propagation; Vol.34PP767-772 and for example, 1986), mention the experimental technique of utilizing thick chip substrate to come widening frequency band in the literary composition, but utilize parasitic patch, will inevitably increase antenna volume and weight, and in array design, increase complexity.When using thick substrate approach, for the probe feed situation, must solve owing to use the caused problem of long feed, because the inductance that probe is introduced, make the frequency band of this structural antenna usually in 10%, the report that has once proposed, on paster, cut out a little garden seam round probe, the electric capacity of introducing will be offset part probe inductance, can obtain 16% frequency range, referring to " thick microstrip antenna probe compensation " (" Probe compensation in thickmicrostrip patches " Electron.Lett, Vol.23 PP606-607,1987).Recently,, obtained to surpass 30% frequency range, yet the cross polarization of " U " shape groove paster antenna is higher, can't be used for simple circularly polarised along with the use of " U " shape groove, therefore, the application that above-mentioned several forms all can't be desirable.People once expected use " L " shape probe, and once in other Antenna Design, used, as " electric coupling rotation shape antenna " (" Electromagneticallycoupled curl antenna " Electron.Lett, Vol 33 PP1003-1004,1993) still, in the design for thick microstrip antenna, still nobody works out better method so far.
The purpose of this utility model, be in order to overcome the defective in the prior art, design a kind of paster antenna that is used for " L " shape probe feed of microstrip antenna, make it that basic improvement all arranged aspect frequency range and the gain, also can be used for simple circularly polarised pattern simultaneously.
The utility model relies on following technical proposals to realize, the paster antenna of a kind of " L " shape probe feed, comprise and be parallel to strip transmission line that installs above the ground plate and " L " shape feed probes, the N type coaxial fitting that is connected with transmission line, it is characterized in that, the horizontal bending segment of " L " shape probe top, install rectangular patch abreast, the distance of the two maintenance is s, and the vertical range between rectangular patch and ground plate is H; The vertical bending segment of " L " shape probe is connected to N type coaxial fitting inner wire by transmission line.
The physical dimension that influences the paster antenna performance parameter is labeled as respectively: the rectangular patch dual-side is Wx, Wy, and thickness is t, and " L " shape probe diameter is 2R, horizontal bending segment is L, and vertical bending segment is b, and inflection point and rectangular patch y back gauge are D, the wide n of strip transmission line, thick m.
This patch-antenna structure can be that a unit uses, and also can the parallel connection of a plurality of unit use, and keeps at a distance between each unit rectangular patch.
The material of paster antenna can be with cheap aluminium sheet and copper coin.
Major advantage of the present utility model is, compares with traditional microstrip antenna, at the aspect of performance of frequency range and gain basic change arranged all, when standing-wave ratio less than 2 the time, bandwidth surpasses 30%, and this structure also can be used for simple circularly polarised radiation mode.
