Abstract
The invention relates to a micro surface patch passive antenna, which is characterized in that the micro surface patch passive antenna is suitable for receiving various right-hand-circular polarized satellite navigation (including but not limited to GPS, a Big Dipper System and a Galileo System) signals. Through adjusting the combination manner of patches, the optimal effect of uniformly receiving multiple satellite navigation signals can be achieved; the dual-feeding manner through probes is adopted, so that a feeding point can collect and send resonance signals to a rear end amplification processing circuit, thereby ensuring the accuracy degree of a phase center and miniaturizing the antenna on the premise of not influencing the receiving performance of the antenna.
Description
Technical field
The present invention relates to satellite navigation positioning technical field, relate in particular to a kind of miniature Surface Mount passive antenna.
Background technology
" Big Dipper " NAVSTAR more and more receives people's attention.Equally, the GALILEO in GPS of USA, Muscovite GLONASS and Europe is just used widely." Big Dipper " NAVSTAR of China's independent research has also satisfied the domestic and surrounding area user demand to satellite positioning navigation.The above-mentioned satellite navigation and location system that comprises China's " Big Dipper " all adopts the technical system of launching a plurality of frequency right-handed circular polarization satellite navigation signals simultaneously.
Miniature sheet Surface Mount passive antenna is the Primary Component that miniaturization satellite navigation terminal such as various handheld, vehicle-mounted, intelligent navigation mobile phones receives satellite navigation signals.
Generally, antenna size is big more, and is good more to the receptivity of wireless signal.But owing to the restriction of miniaturization terminal equipment to antenna pattern and physical size, usually compelled size of dwindling satellite navigation aerial causes the satellite navigation signals receptivity to descend, and influence is used.Therefore, improve constantly the antenna receptivity, expanding the antenna miniaturization potentiality is very necessary and urgent technical need all the time.
Summary of the invention
In view of above-mentioned existing in prior technology problem, the purpose of this invention is to provide a kind of miniature Surface Mount passive antenna, under the prerequisite that does not influence the antenna receptivity, make antenna size microminiaturized.
Know-why of the present invention is applicable to that all adopt the satellite navigation signals of right-handed circular polarization system in (comprising the navigation system that other adopt similar principle) satellite navigation system service frequency ranges such as GPS, the Big Dipper, GLONASS, Galileo, comprises types such as single frequency point, a plurality of frequency or broadband.
Because antenna applications is in mobile phone, panel computer, all kinds of equipment such as hand-held, vehicle-mounted, size and weight all have restriction.Require working frequency range about 1.2GHz, if the employing relative dielectric constant is 10 medium, the length of side of common patch size is just about 35mm.According to a preliminary estimate, must seek help from the more medium substrate or the rational fluting form of high-k.Relate to the square that paster is 23mm * 23mm among the present invention, paster is communicated with through the edge via hole.
Through the epoxide-resin glue water cure, guarantee fully bonding between paster and the medium.Paster adopts the right-handed circular polarization receive mode simultaneously, to reach the optimum signal reception.
For satisfying the characteristic requirements of the axial ratio≤3dB in the bandwidth, adopted probe double-fed mode among the present invention, will present and a little collect resonance signal and be sent to the rear end amplification treatment circuit, guaranteed the levels of precision of phase center point.In the described probe double-fed, feedback point position is not the centre at antenna, but on the X.Y direction of principal axis, does small adjustment.The periphery of two probes all will be reserved insulation layer.
Technical scheme by the invention described above provides can find out that the present invention has reduced the size of antenna, and does not influence the antenna receptivity.

Embodiment
The radiant section of antenna sees that Fig. 1 profit is shown in Figure 2.Paster 1 (1) and paster 2 (5) lay respectively at the front of medium 1 (2) and medium 2 (6).Paster 1 sharp paster 2 is communicated with through paster top edge via hole (4).The fermentation of medium 2 all keeps, and as the floor, the reverse side of medium 1 keeps the part that coincides with paster 2, and stamps abundant edge via hole all around.Two dielectric substrates are processed respectively, at last will be to pasting.Can adopt epoxy resin glue to solidify, middle no paster is partly coated thin layer glue, daub not on the metal covering, and after two substrates compressed, peripheral edge can be coated with on a little mucilage sealing.The relative dielectric constant of two layer medium all is 9, and the length of side is 23mm * 23mm, and thickness is 3mm.Two probes (3) are in order to connect paster 1 and base drive circuit (10).The insulation circle district that probe passes through is left in attention on floor (7).
The feed of antenna is seen Fig. 3.The figure that just looks like of medium substrate processes, and reverse side keeps the floor.Two termination probes of device (12), two ends connect matched load (13) and signal input part (14) respectively in addition.The device bottom surface is ground plate (15), and enough via holes (16) are arranged above.After the probe alignment, feed substrate left-hand thread is on the antenna floor, and after compressing, the edge daub guarantees that two floors fully contact.
It will be appreciated by those skilled in the art that: under the prerequisite that does not deviate from broad scope of the present invention, can change the foregoing description.Thereby the present invention is not limited in disclosed specific embodiment, and its scope should contain core of the present invention and the interior all changes of protection range that appended claims limits.
