Description
Technical field
The invention belongs to a kind of double frequency-band microstrip antenna, be specifically related to a kind ofly novelly design and produce the symmetrical GPS-BD double frequency-band of the circle that forms circular polarization microstrip antenna in the single-layer medium plate.
Background technology
Along with the effect more and more significant that Technique of Satellite Navigation and Positioning plays in military-civil field, people are increasingly high to the attention rate of satellite navigation and location system, and are also increasingly high to the requirement of satellite navigation.High accuracy, high stability all are the developing direction of satellite navigation.The satellite navigation system of having used at present has GPS of USA, and Muscovite GLONASS also has Chinese dipper system.The compatible receiver of multisystem aspect calculation accuracy and the reliability all tool have great advantage, in the high accuracy time service was used, the dipper system of use China independent development had higher fail safe, has broken away from the dependence fully to GPS simultaneously.The systemic breakdown that causes because of not time service of GPS once appearred in the cdma network of China in history.So multisystem is integrated is later satellite positioning navigation Equipment of Development trend, and antenna also is faced with the compatible problem of multisystem as the important component part of satellite navigation, just multiband aerial.
Because the microstrip antenna volume is little, in light weight, section is low and be easy to processing and fabricating, and the ten minutes of in the satellite navigation receiving system, using at present is extensive, but that one of shortcoming of microstrip antenna is a relative bandwidth is narrower.For GPS, the receiving system that BD is compatible needs antenna on the signal frequency of these two systems, all will realize normal reception, and single microband antenna unit is difficult to realize that so big bandwidth receives the signal of GPS and these two frequencies of BD simultaneously.For satisfying this demand, existing GPS, the implementation of BD double frequency reception antenna mainly contains two kinds: one, two antenna element GPS unit and BD unit are placed side by side; Two, two antenna element laminations are placed; Method for designing like 200710099065.6 1 kinds of double frequency round polarized laminated micro band antenna of the patent No.; 200920045847.6 1 kinds of GPS of the patent No. and dual frequency active reception antenna of the Big Dipper, 200920013024.5 1 kinds of two-band receiving antennas of satellite navigation of the patent No. etc. are said.For first kind of scheme; Its modes of emplacement arranged side by side can influence characteristics such as antenna antenna pattern and axial ratio separately; Because GPS; The electromagnetic wave of BD system all is the mode of the right-handed circular polarization of employing, and it all is non-symmetrical structure that two antenna elements placing side by side can cause concerning each antenna element.The mode of placing side by side simultaneously also is unfavorable for the miniaturization of antenna.Dual-band antenna with respect to second kind of stacked system of modes of emplacement arranged side by side has avoided occurring the asymmetric situation of structure; But it still need make two independent antenna elements; And need both be combined through the mode of conductive adhesive; Need guarantee the relative position of the two in the bonding process, complex manufacturing process, and cost is high.
Summary of the invention
The purpose of this invention is to provide a kind of excellent wide angle circular polarization and zero that can realize and differ characteristic, have low section simultaneously, processing and fabricating is the individual layer double-frequency micro-strip antenna simply and easily.
The present invention realizes like this; A kind of individual layer double-frequency micro-strip antenna; It comprises the microwave-medium substrate, and the center of microwave-medium substrate is provided with the central circular radiating element, and the place, periphery of central circular radiating element is provided with circular ring-shaped radiation unit; Certain annular space is arranged between central circular radiating element and the circular ring-shaped radiation unit; The inner edge place of circular ring-shaped radiation unit has the grounded metal hole, and feed probes is installed on the circular ring-shaped radiation unit, on the microwave-medium substrate symmetrically have a mounting screw hole.
The center of described central circular radiating element has rectangular channel.
Described circular ring-shaped radiation unit outer rim place is provided with the tuning minor matters of gear-like.
Advantage of the present invention is that this antenna adopts individual layer circle symmetrical structure, inner circular chip unit, outside employing annular unit.Characteristics such as this structure has realized that excellent wide angle circular polarization differs characteristic with zero, has low section simultaneously, and processing and fabricating is simple and convenient, this kind structure extremely helps the debugging in the fabrication and processing process simultaneously.

Embodiment
Below in conjunction with accompanying drawing and embodiment type of the present invention is introduced in detail:
As shown in Figure 1; It comprises microwave-medium substrate 1 a kind of individual layer double-frequency micro-strip antenna; The center of microwave-medium substrate 1 is fixedly connected with central circular radiating element 5; The center of central circular radiating element 5 has rectangular channel, and the place, periphery of central circular radiating element 5 is fixed with circular ring-shaped radiation unit 4, between central circular radiating element 5 and the circular ring-shaped radiation unit 4 certain annular space is arranged; Circular ring-shaped radiation unit 4 outer rim places 4 tuning minor matters 7 that are furnished with gear-like symmetrically; The inner edge place of circular ring-shaped radiation unit 4 has grounded metal hole 6 uniformly, and feed probes 3 also is installed on the circular ring-shaped radiation unit 4, on the microwave-medium substrate 1 symmetrically have 4 mounting screw holes 2.
Two of double-frequency micro-strip antenna employings of the present invention are positioned at the resonant element on one deck medium and realize; Symmetry for the structure that guarantees two antenna elements; The form that realizes can only be that a resonant element is positioned at the center, and another resonant element is positioned at the outside and the assurance center symmetry of center cell.Because the frequency of BD (central circular radiating element 5) is higher, so the position of BD resonant element centering can make final antenna volume minimize like this.The BD radiating element adopts the form of single-point feedback.
Concrete manufacturing process of the present invention is following, confirms the dielectric constant of the medium substrate of selecting for use at first as requested, dielectric-slab thickness.Dielectric constant influences the size of radiating pattern, and the area of microband paste and the thickness of substrate have determined the operating frequency of antenna.Because the restriction (being generally 0.1mm) of printed board machining accuracy; Edge in circle suitably adds some minor matters, is used for adjusting little skew, simultaneously; After antenna plate machined, the frequency shift (FS) that these minor matters can be used for carrying out causing owing to sheet material dielectric constant deviation was finely tuned.
Rectangular groove is opened at the center of circular microstrip paster, adjusts the degree that degenerate mode separates through length and the width of adjusting rectangular groove and forms circular polarization at last.
The suitable place punching of impedance is selected in the corresponding different character impedance in different position on the paster, is used for installing feed probes.
Confirm after the internal element, outwards placing annular radiating element apart from a distance, circular cell outer.The inside circumference of the annular element metallic vias ground connection that evenly distributes, the size of metallic vias and the density degree that distributes are looked concrete situation and decide, the intensive placement metal aperture of need trying one's best in general, but to prevent the situation of structural strength deficiency.
Annular element adopts the two point feeding classification to form circular polarization, selects suitable impedance position to beat metal aperture feed probes is installed.
