Carry out detailed description in the face of specific embodiment down:
Shown in Fig. 5 a, Fig. 5 b, be the external structure of antenna, antenna external diameter Φ≤200mm in the specific embodiment, highly≤60mm (containing radome and RF jack sizes).Entire antenna is sealed in the radome, and radome adopts the electromagnetism electromagnetic wave transparent material, and hood-shaped is the frustum of a cone, and wall thickness≤0.5mm has the thick outward flange of 3mm.This structure light weight, pass through ripple, have enough rigidity.Radome can adopt quartzy composite material in the specific embodiment, and this material is more expensive, if only Ground Application can be used lower-cost glass-reinforced plastic material instead.
Again referring to Fig. 1 and Fig. 2; It is the antenna shapes structure of removing radome; The center is the center radiation unit block of antenna; It loads lithographic plate by anise top, the short oscillator of the covering of the fan broadening of 4 pairwise orthogonals and form at 4 coaxial feed seats of bottom that (detailed view of center radiation unit block is referring to Fig. 3-Fig. 4).Around the center radiation unit block two groups of parasitic couplings unit (passive coupling) are arranged.One group is arranged in center radiation unit block periphery, is made up of 12 coupling plates of equidistantly radially arranging; Another group is arranged in below the center radiation unit block top board, circumferentially is 45 with four oscillators and arranges.The employing welding procedure is shaped, and reduces the distortion that welding causes as far as possible, must guarantee form and position tolerance.Run through an assembled metal screw rod between ground plate in center of antenna extremely down by the top.Anti-coupling trip bolt has distributed on the ground plate chamber.
Ground plate chamber interior diameter 173mm.The high 4mm of inner chamber just in time is placed in one feeding network.The chamber outward flange links to each other with carrier with radome.There are 8 the screw of isolate conductive piece and the flange mounting hole of the SMA that links to each other with receiver (F) are installed on the chamber, the end.Place medium three printed line networks at the bottom of the ground plate behind the chamber, add and cover ground plate.Trip bolt on the ground plate chamber comprise the screw that is installed to the isolate conductive piece can the isolation strip line between coupling and suppress dull and stereotyped mode and improve network feed performance, these fastening screws are all joined after last ground plate assembling dozen.
Two groups of parasitic couplings unit comprise:
First group of parasitic couplings unit: the radially parasitic couplings sheet (oblique coupling plate) by 12 are uniformly distributed with outside the center radiation unit is formed.As shown in Figure 6, the inner side edge of oblique coupling plate becomes 45 ° of angles in the specific embodiment with horizontal plane, and outer side edges becomes 40.6 ° of angles with horizontal plane, and angle can be regulated as required;
Second group of parasitic couplings blade unit: constitute by 4 rectangle coupling pieces, be arranged in below the center radiation unit block top board, circumferentially be 45 with four oscillators and arrange.
The basic fundamental characteristic of the antenna of specific embodiment:
1) antenna of the present invention constitutes the center radiation unit block by four orthogonal short oscillators of tops loading on the ground plate chamber.Four short oscillators are the segment angle sheet, and the covering of the fan broadening angle makes its oscillator height be no more than λ/8, the wide 50mm in oscillator upper end.Loading top board, to be the corner cut octagon dull and stereotyped, is to be that 45 ° of corner cuts of square plate rotation of 65mm form by two length of sides.
2) the feed base of four short oscillators is a coaxial type.Short oscillator bottom inner wire development length just in time guarantees to be connected with the respective feed points of network feed line.Its outer conductor is 4 corresponding perforates of last ground plate, is filled with the Teflon microwave-medium between inner and outer conductor.Coaxial inner and outer conductor size is except that being the 50 Ω design by characteristic impedance; Also need adjust electric capacity at the bottom of the oscillator feed end; Make itself and the reactive balance of lacking oscillator, realize the Broadband Matching characteristic of electronically small antenna feed, guarantee normal reception a plurality of navigation satellite constellation signals.
3) around the center radiation unit block be the parasitic couplings unit of two group switching centres symmetry.One group is arranged in center radiation unit block periphery, is made up of 12 coupling plates of equidistantly radially arranging, and each coupling plate is inclined ladder shape; Another group coupling plate is made up of 4 rectangular slabs, is arranged in below the center radiation unit block top board, circumferentially is 45 with four oscillators and arranges.Geometric position and size through adjustment parasitic couplings plate can make the interaction of center radiation unit block and coupling plate reduce the radiation phase center as far as possible, and it is stable to help the radiation phase heart.The notable feature of this center symmetry, low clearance, flat structure is to have the stable radiation phase heart, and design phase heart dispersion can be less than 1mm;
4) made the ground plate cylindrical cavity that inner height 4mm, a diameter are no more than Φ 180mm to ground plate.Feeding network all sealing is installed in this chamber.4 oscillators on the ground plate, 4 metallization via holes, 4 wire ends (go up 4 ports that dielectric-slab connect antenna) corresponding with it that pass on the ground plate through its inner wire probe connect; The feeding network other end links to each other with receiver, links to each other with RF socket inner core on being installed in down ground plate through the metallization via hole.This socket can stretch out from base plate center or side, and the RF socket adopts SMA/TNC (F) form.This package assembly except that compactedness, globality, easy of integration, also have good electromagnetic compatibility (EMC) property;
5) have complete centrosymmetric architectural feature, the heart is stable mutually to utilize the center radiation unit block and the interaction of coupling plate not only to help radiation.The more important thing is and improved roll-offing and the front and back specific characteristic of directional diagram, reflection and scattering around suppressing preferably reach good anti-multipath performance.Compare with the antenna that uses the Choke ring, this antenna has wideer working band, wideer covering wave beam, structure more lightly, compacter, more convenient installation.
