Description
Technical field
It is exactly specifically a kind of omnidirectional antenna the present invention relates to antenna technical field, more particularly to a kind of omnidirectional antenna
Array.
Background technology
Omnidirectional antenna shows as 360 degree of homogeneous radiations on figure in the horizontal direction, that is, usually described non-directional,
Because omnidirectional antenna can cover larger scope, therefore it is used widely in the communications field.Common omnidirectional antenna
Including dipole antenna, monopole antenna, biconical antenna, monocone antenna and loop aerial etc..But, it is existing complete
Some particular demands can not be met to antenna gain is low, in fact, there is not yet gain in the prior art reaches 10dBi
Single omnidirectional antenna.
In order that gain is more than more than 10dBi, people replace single omnidirectional antenna to use using omni-directional antenna arrays.
The most frequently used aerial array is collinear array row, and it is to be connected by multiple low gain omnidirectional antenna units along an axle
Or be formed in parallel.Wherein, series feed collinear array row include Franklin (Franklin) aerial array,
Anti-phase (the meander-line phase reversal) aerial array of meander line, coaxial transposition (transposed coaxial
Sections) aerial array etc..Although omni-directional antenna arrays can improve the gain of omnidirectional antenna, also cause omnidirectional
The complication of feeding network inside aerial array, and be lost also very big.
In addition, omnidirectional collinear antenna array row mentioned above are mainly used in very high frequency(VHF) (VHF) and superfrequency (UHF)
In wave band, and these existing omni-directional antenna arrays can not be applied in Ka wave bands (Ka-band) or higher frequency section
In, will very if by force applied these omni-directional antenna arrays in Ka wave bands (Ka-band) or higher frequency section
Difficulty reaches required gain, and this is primarily due in Ka wave bands (Ka-band) or higher frequency section, transmission network
The high loss of network counteracts the increment of antenna gain.Further, since the feeding network of existing collinear array row can be destroyed
The rotational symmetry of aerial array and the scalar property of radiation mode, thus existing omnidirectional collinear antenna array row can not also answer
Use and high wireless channel measurement field is required to omni-directional.
Thus, those skilled in the art need that a kind of feed network structures are simple, it is low to be lost badly, and may apply to
In Ka wave bands (Ka-band) or higher frequency section, the high-gain omnidirectional antennas of wireless channel measurement requirement can also be met
Line.
The content of the invention
In view of this, the technical problem to be solved in the present invention is to provide a kind of omni-directional antenna arrays, solves prior art
Middle omni-directional antenna arrays are complicated, high energy consumption, it is impossible to be applied in Ka wave bands or higher frequency section, and can not enter
The problem of row wireless channel measurement.
In order to solve the above-mentioned technical problem, the specific embodiment of the present invention provides a kind of omni-directional antenna arrays, bag
Include：First biconical antenna unit, for receiving or sending the first high-frequency signal；Second biconical antenna unit, is stacked in
On the first biconical antenna unit, for receiving or sending and first high frequency signal amplitude and phase all same
Second high-frequency signal；Feeding network, is embedded in the first biconical antenna unit and the second biconical antenna unit,
For launching after high-frequency signal is distributed into first high-frequency signal and second high-frequency signal, or by institute
State the first high-frequency signal and second high-frequency signal synthesis high-frequency signal is received.
According to the above-mentioned embodiment of the present invention, it is known that omni-directional antenna arrays at least have the advantages that or special
Point：Using two biconical antenna being stacked with units (biconical antenna element), and it is embedded in bipyramid
Feeding network (feeding network) composition omni-directional antenna arrays in antenna element, are stacked with due to two
Biconical antenna unit is mirrored into symmetrically, the first high frequency letter formed between the first tapered assemblies and the second tapered assemblies
Number, and the second high frequency signal amplitude for being formed between triconic component and the 4th tapered assemblies and phase all same,
Therefore the omni-directional antenna arrays of the present invention can obtain more than 10dBi gain in Ka wave bands or higher frequency section；Separately
Outside, because biconical antenna unit and feeding network are rotationally symmetrical, so the omni-directional of high-frequency signal is good；Feeding network
The center of biconical antenna unit is arranged at, the rotational symmetry of biconical antenna unit will not be destroyed, therefore, the present invention is carried
The omnidirectional antenna of confession can be also used for measuring wireless channel.
