Abstract
The invention discloses a microstrip coupled radiation unit for a broadband dual-polarized directional base station antenna. The unit comprises a reflecting bottom plate, a feed baron and radiating arms fixed on the reflecting bottom plate, wherein the number of the radiating arms is four; every two of the four radiating arms are opposite to each other to form a symmetrical vibrator; the two groups of formed symmetrical vibrators are arranged in a cross shape; and the feed baron is fixed with the radiating arms so as to feed the vibrators in a coupling mode through an insulated fixing device. The microstrip coupled radiation unit has excellent gain, standing wave, isolation, cross polarization, third-order intermodulation and other electric properties. Therefore, the communication quality in a service area can be well guaranteed from the aspect of antennas.
Description
Technical field
The present invention relates to a kind of antenna element, be specifically related to a kind of microstrip coupled radiation unit of broadband dual-polarized directional base station antenna.
Background technology
The base station is the important component part of mobile communication system, and antenna is the critical component of base station front end, plays a part to accept and the carrier wave that transmits.In mobile communications network, antenna is directly determining the covering of base station network and the transmission of signal, and is most important for the mobile communication quality.
The dual polarization mobile base station antenna is the indispensable part in each base station, and its performance directly influences the quality of communication; And radiating element is the key component that influences dual polarization mobile base station antenna performance as the element of dual polarization mobile base station antenna.
In the prior art, the radiating element of dual polarization mobile base station antenna generally all realizes that by welding procedure feed Ba Lun is to the oscillator feed.
There is following shortcoming at least in above-mentioned prior art: complex structure, cost height, processing difficulty are big.
Summary of the invention
Goal of the invention: the objective of the invention is at the deficiencies in the prior art, the microstrip coupled radiation unit of a kind of function admirable, simple in structure, service-strong broadband dual-polarized directional base station antenna is provided.
Technical scheme: the microstrip coupled radiation unit of a kind of broadband dual-polarized directional base station antenna of the present invention, comprise reflected bottom plate, feed Ba Lun and be fixed on radiation arm on the described reflected bottom plate, described radiation arm is four, four independently radiation arm form symmetrical dipole in twos relatively, formed two groups of symmetrical dipoles are cross to be arranged, forms ± 45 ° of two-way polarization modes; Four radiation arms are the metal stamping structure, can adopt pressing and bending to realize, its material can be a copper, also can be that aluminium etc. is to reduce cost; Described feed Ba Lun fixes by insulation fixture and described radiation arm, and feed Ba Lun is a copper sheets, but mold production also can be finished by precision machined modes such as line cutting or laser cutting; For guaranteeing good third order intermodulation index, the present invention adopts the air microstrip Ba Lun feed that is coupled, and does not have pad between feed Ba Lun and the oscillator, thereby has guaranteed good third order intermodulation; Described insulation fixture is high temperature resistant sludge proof nonmetallic materials, can certainly be other insulation exotic materials, as non-conductive and do not inhale the polytetrafluoroethylmaterial material of ripple; But insulation fixture mould words are produced, so cost is very low.
The cross center of two groups of symmetrical dipole formations overlaps with the center of described reflected bottom plate.
Reflected bottom plate adopts lightweight aluminium, and the both sides bending has guaranteed the electric property of radiating element and the mechanical strength of base plate.
The radiation arm base is provided with positioning pillars, is provided with to be used for the screwed hole that is connected with reflected bottom plate on positioning pillars, and described four radiation arms are fixedlyed connected by screw or rivet with described reflected bottom plate.
Beneficial effect: the present invention compared with prior art, its beneficial effect is: 1, electric properties such as gain of the present invention, standing wave, isolation, cross polarization, third order intermodulation are outstanding, thereby can well guarantee the communication quality in the service area from the antenna aspect; 2, the present invention can realize the half power lobe width of broad in when battle array group, is particularly suitable for being used in horizontal half power lobe width and is in the Bipolarization antenna for base station design of 90 ° or 105 °; 3, the present invention is in light weight, stable performance, and cost is low, and conformity of production is good, the production efficiency height; 4, function admirable of the present invention, simple in structure, use reliable.
