Description
Technical field
The present invention relates to mobile communication dual-band and dual-polarization antenna for base station, relate in particular to a kind of plane double helix array of dual-band and dual-polarization antenna for base station.
Background technology
At present, the arranged in arrays mode of dual-band and dual-polarization antenna for base station employing has two kinds: a biserial orthoscopic array and a row orthoscopic array.These two kinds of arranged in arrays modes all have its shortcoming:
Biserial orthoscopic array is asymmetric on the wide dimension of reflecting plate; Cause the horizontal plane main pole major lobe of directional diagram to point to the off-center position; Horizontal plane cross polarization directional diagram symmetry variation, the cross polarization discrimination ratio within ± 60 ° degenerates, and reflecting plate requires very wide;
Distance between one row orthoscopic array medium-high frequency Hertz antenna and the low frequency Hertz antenna is too small, and it is very big to influence each other, and particularly the low frequency Hertz antenna causes high frequency direction figure to produce the deterioration that can not expect to the shade of high frequency Hertz antenna.
Summary of the invention
The object of the invention just is to overcome the shortcoming and deficiency that prior art exists, and a kind of plane double helix array of dual-band and dual-polarization antenna for base station is provided.
The objective of the invention is to realize like this:
The present invention includes high frequency Hertz antenna, low frequency Hertz antenna, reflecting plate and feeding network;
High frequency Hertz antenna, low frequency Hertz antenna are arranged on the front of reflecting plate, and feeding network is arranged on the back side of reflecting plate;
The high frequency Hertz antenna replaces in twos, and left and right sides sidesway constitutes the high frequency radiation array; Coaxial line in the feeding network is given high frequency Hertz antenna feed; Wherein the outer conductor of coaxial line is connected on the high frequency link slot of high frequency Hertz antenna, and the heart yearn of coaxial line is connected on the high frequency brace at high frequency Hertz antenna top;
The low frequency Hertz antenna replaces corresponding left and right sides sidesway with the direction opposite with the high frequency Hertz antenna and constitutes the low frequency radiation array; Coaxial line in the feeding network is given low frequency Hertz antenna feed; Wherein the outer conductor of coaxial line is connected on the low frequency link slot of low frequency Hertz antenna, and the heart yearn of coaxial line is connected on the low frequency brace at low frequency Hertz antenna top.
Working mechanism:
The present invention is a kind of plane double helix array, is datum line with reflecting plate horizontal plane axis, supposes that high frequency Hertz antenna and low frequency Hertz antenna are evenly arranged in respectively on the datum line, does the sidesway operation then.The high frequency Hertz antenna replaces left and right sides sidesway in twos from top to bottom, and amount of side-shift can equate, also can not wait; The low frequency Hertz antenna replaces left and right sides sidesway in twos from top to bottom with the direction opposite with the high frequency Hertz antenna, and amount of side-shift can equate, also can not wait.The definite of amount of side-shift is as the criterion to meeting the demands with horizontal lobe width adjustment.
Hertz antenna can not influence the directional diagram of vertical plane at the sidesway of horizontal plane.Because horizontal plane and vertical plane quadrature, horizontal direction sidesway can be between each Hertz antenna of vertical direction additional phase error.
Hertz antenna sidesway in the horizontal direction influences the directional diagram of horizontal plane, because its additional phase error between each Hertz antenna in the horizontal direction forms the array effect, and with respect to orthoscopic arranged in arrays mode, can compression level ground roll lobe width.
Overcome interactional problem between a row orthoscopic array medium-high frequency Hertz antenna and the low frequency Hertz antenna;
Broken in the biserial orthoscopic array asymmetry on the wide dimension of reflecting plate; Increased the distance between distance, low frequency oscillator and the low frequency oscillator between high frequency oscillator and the high frequency oscillator, to horizontal lobe width, front and back than, ± indexs such as cross polarization discrimination ratio within 60 °, isolation have the improvement effect.
The present invention is a kind of plane double-spiral structure, and the orthoscopic array compared to traditional has advantage and good effect:
Under the situation that does not change elevation radiation patytern, can adjust the horizontal plane lobe width through the amount of side-shift of adjustment Hertz antenna horizontal direction; Can adjust cross polarization discrimination ratio through adjustment reflecting plate width and side arm height; Can increase distance between high frequency Hertz antenna and the low frequency Hertz antenna to reduce influencing each other between the high and low frequency; Can increase distance between high frequency Hertz antenna and high frequency Hertz antenna, low frequency Hertz antenna and the low frequency Hertz antenna to improve high-frequency isolation degree and low frequency isolation degree; The width that can reduce reflecting plate has improved the space availability ratio of antenna to reduce windage.
The present invention is applicable to that being used for dual-band and dual-polarization antenna for base station high and low frequency oscillator arranges this field.
