Description
Technical field
The utility model relates to a kind of radiating element of antenna, relates in particular to a kind of radiating element that is applied on the bipolar antenna for base station.
Background technology
Along with the development of mobile communication technology, more and more higher to the requirement of antenna for base station.Antenna for base station generally is combined into array format by the radiating element of same form, to obtain high gain.The radiating element of antenna for base station generally has two kinds of forms at present, and a kind of is the air microstrip aerial form, and a kind of is the oscillator form.The air microstrip aerial form has shortcomings such as narrow bandwidth, cross polarization be big; The antenna of oscillator form has the shortcoming that needs the balance conversion, and oscillator form antenna is departing from polarization resolution meeting variation, just polarization mismatch on the direction of greatest irradiation.Finish by the ribbon feeder that plays feed and supporting role simultaneously as the feed of common folded dipole, a ribbon feeder connects the reflection floor, another root connects microstrip transmission line, the polarization mismatch rate was big when the radiating element that such folded dipole is formed was applied to dual polarized antenna, loosely organized, area occupied is big, and single folded dipole impedance ratio is bigger, is not easy coupling.
Summary of the invention
Technical problem to be solved of the present utility model: a kind of radiating element that is applied on the Bipolarization antenna for base station is provided, this radiating element has improved the polarization mismatch rate of dual polarized antenna, increase the polarization resolution of dual polarized antenna, compact conformation, firm, reduce the radiating element area occupied, the feed form of this radiating element is mated radiating element easily.
The utility model solves the technical scheme that its technical problem adopts: a kind of radiating element that is applied on the Bipolarization antenna for base station, it comprises the distortion folded dipole, carves son, feeding network, reflecting plate, microstrip transmission line, ribbon feeder, described distortion folded dipole is an arc, four distortion folded dipoles constitute a circle, the son made from dielectric material between the distortion folded dipole of carving separates also fastening, it is right that two relative distortion folded dipoles are formed oscillator, each pair is connected with a feeding network oscillator, and two feeding networks are separate.
Two ribbon feeders that each distortion folded dipole has been passed through feed and supporting role are connected with feeding network, and two ribbon feeders pass through the microstrip transmission line connection of 1/2 wavelength.
The beneficial effects of the utility model:
1. four distortion folded dipoles of the present utility model constitute circle, have improved the polarization mismatch rate of dual polarized antenna.
2. the son made from dielectric material between the distortion folded dipole of the present utility model of carving separates and fastening, makes radiative unit structure compactness of the present utility model, and firmly, area occupied is few.
3. the ribbon feeder of the novel distortion folded dipole feeding network of this use connects the microstrip line that a segment length is 1/2 wavelength, and 1/2 wavelength microstrip line has balance and impedance conversion effect, makes coupling be more prone to.
Further specify the utility model below in conjunction with the drawings and the specific embodiments.
