Description

Angle reflecting flush printed board dipole antenna
Technical field
The present invention relates to a kind of printed board dipole antenna, especially relate to a kind of angle reflecting flush printed board dipole antenna.
Background technology
The application of dipole antenna is very extensive, both can independently use, or as the component units of antenna array, can also be as the feed of complex antenna such as surface antenna.Printed dipole antenna adopts the printed circuit board technology processing and fabricating, compare with traditional line dipole antenna, have that planar structure, volume are little, in light weight, low cost of manufacture, be easy to extensive integrated characteristics, it is limited or require the use of occasion such as conformal assembling to be more suitable for installing space.In the design of printed dipole antenna, usually use with antenna not coplane and size realize the half space radiation much larger than the reflector of operation wavelength, also can not use reflector to realize omnidirectional radiation.In modern radio-frequency or microwave communication system, often the directivity to antenna proposes certain requirement, and for example mobile communication base station sectors cover antenna, antenna for mobile phone weaken head radiation, surface antenna directivity feed and phased array.Along with the development of broadband connections, require antenna in wideer frequency band, to work gradually in addition.
Summary of the invention
The purpose of this invention is to provide a kind of angle reflecting flush printed board dipole antenna.
The technical solution adopted for the present invention to solve the technical problems is as follows: the one side at the printed board substrate is provided with the microstrip transmission line layer, and a side of microstrip transmission line layer has the metallization via hole, and the opposite side of microstrip transmission line layer connects the coaxial feed interface; Be provided with the corner reflection plane layer of ingot type at the another side of printed board substrate near coaxial feed interface one side, be provided with the microstrip balun layer in the middle of the corner reflection plane layer of ingot type, be provided with radiation both arms layer near metallization via hole one side at the another side of printed board substrate; The microstrip transmission line ply is on the microstrip balun layer of reverse side; Radiation both arms layer connects metallization via hole and microstrip balun layer, and the corner reflection plane layer of ingot type connects microstrip balun layer and coaxial feed interface.
The useful effect that the present invention has is: compare with traditional printed dipole antenna that does not have the corner reflection plane, this antenna has increased impedance bandwidth, has improved the forward radiation gain, has suppressed backward radiation.This antenna has kept simultaneously that planar structure, volume are little, in light weight, low cost of manufacture, be easy to extensive integrated characteristics, and it is limited or require the use of occasion such as conformal assembling to be fit to very much installing space.

Embodiment
As shown in Figure 1 and Figure 2, the present invention is that the one side at printed board substrate 1 is provided with microstrip transmission line layer 2, and a side of microstrip transmission line layer 2 has metallization via hole 3, and the opposite side of microstrip transmission line layer 2 connects coaxial feed interface 4; Be provided with the corner reflection plane layer 7 of ingot type near coaxial feed interface 4 one sides at the another side of printed board substrate 1, be provided with microstrip balun layer 6 in the middle of the corner reflection plane layer 7 of ingot type, be provided with radiation both arms layer 5 in close via hole 3 one sides that metallize of the another side of printed board substrate 1; Microstrip transmission line layer 2 overlaps on the microstrip balun layer 6 of reverse side; Radiation both arms layer 5 connects metallization via hole 3 and microstrip balun layer 6, and the corner reflection plane layer 7 of ingot type connects microstrip balun layer 6 and coaxial feed interface 4.
The corner reflection plane layer 7 of described microstrip transmission line layer 2, ingot type, microstrip balun layer 6 and radiation both arms layer 5 are the copper layer.
Signal feed-in place of the present invention adopts coaxial feed to be interfaced to the microstrip line transition structure, can use coaxial cable to connect easily.Signal carries out the balanced excitation feed by microstrip balun to the radiation both arms of antenna.The corner reflection plane is extended to the radiation both arms and is opened, can reflecting antenna to the radiation of coaxial feed interface, reduced feeder line and radiation arm degree of coupling, the input reflection loss of antenna is improved.When extension angle, the extended position on corner reflection plane are selected when suitable, reflected wave and radiated wave stack strengthen, and emittance is concentrated forward and produced directive gain, has adjusted the antenna pattern of antenna.The plane of reflection extends at a certain angle and has guaranteed that when pumping signal departs from antenna resonant frequency the in-phase conditions of reflected wave and radiated wave can not worsen rapidly, makes antenna can keep lower input reflection loss in the frequency band of broad.
The coaxial feed of using coaxial cable to connect antenna is interfaced to subscriber equipment, can use.
As shown in Figure 2, Antenna Design instance parameter of the present invention is as follows: the FR-4 printed board of 1.6mm thickness, its dielectric constant 4.6, loss angle tangent 0.018, its length l s=40mm, width w s=56mm; Single armed length l=the 19.9mm of radiation both arms and width w=6mm, the microstrip balun length l p=16mm, the Center Length l on the corner reflection plane of ingot-shaped g=10mm and perimetric length l f=23mm, the width w of microstrip balun p=5mm, the center width w on the corner reflection plane of ingot-shaped g=15mm, extension width w f=51mm, extension angle θ=45 ° and extended position d=5mm, the coaxial feed interface adopts the SMA type connector of standard.Use printed circuit board technology processing and fabricating antenna, its input reflection loss S 11And the standing-wave ratio bandwidth of operation of antenna (reflection) and antenna pattern (three frequencies reflect the directive gain of antenna) are seen shown in Fig. 3,4.
