Description
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.
