Abstract
The invention discloses an array antenna organizing method. According to the method, the antenna array employs staggered arrangement of two adjacent arrays of oscillators, and the staggering spacing between the oscillators is greater than 0. The types of the oscillators includes but are not limited to two forms of vertical/horizontal and +/-45 degrees dual polarization, and also comprises other various types of oscillator forms. The uniqueness and consistency of various array radiation modes are realized via sidewalls of a reflection plate. The staggered arrangement of the antenna array in the method is advantageous in that mutual interferences between oscillator arrays can be effectively reduced, performance parameters such as the isolation degree between the antenna arrays and the beam width are improved, and the space of a base station is saved.
Description
Technical field
The present invention relates to a kind of dislocation group battle array method of array antenna elements, comprise the oscillator arrangement of single-frequency, double frequency and multi-frequency array antenna.This array mainly considers the group battle array mode of antenna oscillator, utilizes dislocation group formation formula to improve the efficiency of transmission of antenna in wireless transmitting system.This invention can be widely used in the field of array antennas such as smart antenna and multiple antennas.
Background technology

Along with array antenna frequency range and array get more and more, the interference between array is more and more serious.In order to reduce this interference, better realizing the transmit-receive diversity effect of MIMO multiple antennas, improving the application scenarios of array antenna, to the research of aerial array group battle array method, there is great meaning.
Summary of the invention
The technical problem to be solved in the present invention:
The object of the invention is the deficiency in order to overcome above-mentioned technical background, a kind of dislocation group battle array method is provided, the demand of cordless communication network pair array aerial signal interference can be met.
Solving this technical problem adopted technical method is: utilize dislocation group formation formula to improve the efficiency of transmission of antenna in wireless transmitting system.
In the inventive method, array format adopts adjacent two row oscillator Heterogeneous Permutations, and oscillator dislocation spacing is greater than 0.
Oscillator type includes but not limited to vertical/horizontal and ± 45 ° of dual polarizations two kinds of forms, also comprises other various forms of oscillator forms.
Combination arrangement between array is not limited to multiple antennas quantity, can be four antennas, eight antennas etc., combination arrangement relation simultaneously between array is not limited to the distributing position in concrete physical space, can be that the horizontal combination of antenna is structured the formation, or vertical cartel is structured the formation, also or horizontal vertical jointly structure the formation, can diversity be there is in the interlace mode between array.
Independence and the consistency of each array element radiation mode is realized by reflecting plate sidewall.
The advantage that the present invention is compared with the existing technology had, feature or good effect:
The present invention for realizing that antenna for base station covers, high-quality call and data transmission ratio, space, saving base station, promote the sector covering problems such as client capabilities and provide a kind of new array antenna group battle array method.Dislocation arrangement oscillator, can effectively reduce between layered transducer elements and mutually disturb, the performance parameters such as the isolation between raising aerial array and lobe width.When antenna index one timing, array antenna elements adopts dislocation arrangement, and antenna size can be made to diminish, and this under the prerequisite ensureing antenna footprint, speech quality, can save space, base station; On the base station of same space, more antenna of can arranging, improves client capabilities.
