Abstract
The utility model relates to an antenna of radiating array telecommunicating base station with high-power micro-band, which is characterized in that a dipole antenna is selected to use for the antenna of mini-band antenna, a linear antenna array with homogeneous side radiation is composed of micro-band and half-wave printing antenna oscillators, a micro-band fed net is feeding with equal width same phase, the distance between adjacent array elements is approximated to half wavelength, a rectangular-shaped radiating element arranged on a basal plate is dipole antenna formed by a segment of double-lined micro-band transmission line which is a symmetrical oscillator antenna, and the cross section of the rectangular-shaped radiating element is a rectangular and belt-type oscillator. Two radiating elements are two arms of the antenna, and are arranged on one line. The electric current of one conductor flows from the start to the end, and the electric current of the other conductor flows from the end to the start. The utility model overcomes the defect of the traditional antenna, and has the advantages of simple structure, small volume, light weight, good stability, uniform index and convenient volume-produce. Because of the simple structure and small volume, a visual shock of an antenna tower for community is alleviated.
Description
Technical field
The utility model belongs to the wireless mobile communications antenna, relates to a kind of microstrip dipole printed antenna that is used for radiation and receiving electromagnetic signals---high-power little band transmission radiating curtain communication base station antenna.
Background technology
At present, the GSM of domestic application, COMA mobile communication base station antenna, what tradition adopted is the feeding network that the little band of class or little band are formed, and common microstrip antenna simultaneously adopts the metal deposition radiation element, and the back side is pasted thin metal layer and is made ground plate.And the oscillator of class micro-strip array antenna and feeding network are divided modes, connect with lead through the assembling back.The antenna of this structure exists that volume is big, weight is big, complex structure, tracking difficulty, cost height, the problem that is not easy to produce in enormous quantities.
Summary of the invention
The purpose of this utility model is to be portable radio device, honeycomb fashion GSM, COMA mobile communication base station antenna and other communication equipment, and a kind of high-power little band transmission radiating curtain communication base station antenna with fabulous radiance is provided.
The high-power little band transmission radiating curtain communication base station antenna content Description of the utility model:
The high-power little band transmission radiating curtain communication base station antenna of the utility model, it is characterized in that: the antenna element of microstrip antenna is selected quadripole subtype antenna for use, form side by little band half-wave printed antenna oscillator and penetrate even linear array, microstrip feed network constant amplitude homophase feed, adjacent array element distance is approximately half-wavelength, reflecting plate be positioned at microstrip feed network below, apart from little band half-wave printed antenna oscillator 1/4 wavelength, substrate adopts ε
γ=3, thickness is that the poly-tetrafluoro double-sided substrate of 1.5mm is made; Little band half-wave printed antenna oscillator and microstrip feed network are produced on the substrate, the strip radiation element of the one side setting on the substrate is that the dipole antenna that the two-wire microstrip transmission line by one section terminal open circuit forms is a doublet antenna, and its cross section is the banded oscillator of rectangle; Two radiation elements are two arms of antenna, come on the straight line, and the electric current of a lead flows to terminal from top, and the electric current of another root lead then flows to top from end.
The high-power little band transmission of the utility model radiating curtain communication base station antenna has overcome the defective that above-mentioned traditional antenna exists, and it is simple in structure, volume is little, in light weight, good stability, index unanimity, is convenient to produce in enormous quantities.The utility model because simple in structure, volume is little, can relax the visual impact that antenna tower cause community.

Have the number of radiant element of certain intervals relevant in the gain of antenna and the antenna array, the quantity that increases the quantity of radiant element in the antenna array or reduce radiant element just can increase or reduce gain.
Its performance index are as follows as a result after tested:
Frequency: 1710～1880MHz;
Gain: 13dB;
Bear power: 200W;
Vertical beam width: 8 °;
Horizontal beam width: 60 °;
Voltage standing wave ratio :≤1.5;
Interface mode 7/16, the cloudy interface of DIN.
