Abstract
The invention relates to the technical field of antennas, in particular to a multiband external antenna of an improved structure. The multiband external antenna comprises a grounding metal tube, a coaxial line and a heat shrink tube, and further comprises a solid metal column, an inner conductor of the axial line is connected with the solid metal column, an external conductor of the coaxial line is connected with the grounding metal wire, one end of the heat shrink tube is sleeved with the grounding metal tube, and the other end of the heat shrink tube is sleeved with the solid metal column. According to the multiband external antenna of the improved structure, a traditional dual-band antenna is improved, and work on two frequency bands can be achieved without a spiral microstrip antenna. The multiband external antenna is simple and scientific in structural design, good in performance, small in size, low in cost, wide in application and high in practicality.
Description
Technical field
The present invention relates to antenna technical field, relate in particular to a kind of multiband external antenna of architecture advances.
Background technology
Antenna is a kind of electromagnetic parts that are used for launching or receiving in wireless device, and its is transformed into guided wave of transmission above-the-line promotion the electromagnetic wave of propagating in unbounded medium (normally free space), or carries out contrary conversion.Antenna is widely used in the engineering systems such as radio communication, broadcast, TV, radar, navigation, electronic countermeasures, remote sensing, radio astronomy.
Along with the development of wireless communication technology, there is multiple communication standard, the frequency range adopting is also had any different, as Chinese two frequency ranges of GSM network using 900MHZ, 1800MHZ, and U.S. GSM uses 1900MHZ, for wireless router, mostly be operated in 2.4GHZ, the trend that develops in addition at present 3.5GHZ, 5.8GHz, correspondingly, also requires the antenna of these equipment under multiband, to work.The screw type microstrip antenna of the general employing of existing dual-band antenna, improve by the shape to screw type microstrip antenna, make them can be for two wave bands, but, the frequency range of this dual-band antenna design trouble, complex structure, work is more approaching, and volume is larger, limit the range of application of dual-band antenna.
Summary of the invention
The object of the invention is to provide for the deficiencies in the prior art a kind of multiband external antenna of architecture advances, traditional dual-band antenna is improved, do not need screw type microstrip antenna can realize two frequency range work, the simple science of its structural design, not only there is better performance, and volume is little, cost is low, application is wide, practicality is very strong.
To achieve these goals, the present invention adopts following technical scheme:
A kind of multiband external antenna of architecture advances, comprise grounded metal pipe, coaxial line and heat-shrink tube, further comprise a solid metal column, the inner wire of described coaxial line is connected with described solid metal column, the outer conductor of described coaxial line is connected with described grounded metal pipe, one end of described heat-shrink tube and the socket of grounded metal pipe, the other end of heat-shrink tube and solid metal column socket.
Wherein, between described grounded metal pipe and solid metal column, leave gap, described heat-shrink tube is coated on the outside in this gap.
Wherein, suppose that wavelength corresponding to resonance frequency that described antenna produces is λ, the odd-multiple that the length of described solid metal column is λ/4 is multiplied by the shortening coefficient of described heat-shrink tube institute loss.
Wherein, the length of described grounded metal pipe is 9～23mm.
Wherein, the length of the new metal column of described reality is 13～25mm.
Beneficial effect of the present invention is: the two waveband external antenna of architecture advances of the present invention, comprise grounded metal pipe, coaxial line and heat-shrink tube, further comprise a solid metal column, the inner wire of described coaxial line is connected with described solid metal column, the outer conductor of described coaxial line is connected with described grounded metal pipe, one end of described heat-shrink tube and the socket of grounded metal pipe, the other end of heat-shrink tube and solid metal column socket, the present invention improves traditional dual-band antenna, do not need screw type microstrip antenna can realize two frequency range work, the simple science of its structural design, not only there is better performance, and volume is little, cost is low, application is wide, practicality is very strong.
brief description of the drawings:
Fig. 1 is the structural representation of the two waveband external antenna of architecture advances of the present invention.
Reference numeral comprises:
1-grounded metal pipe; 2-coaxial line; 3-heat-shrink tube; 4-solid metal column; 5-inner wire; 6-outer conductor.
embodiment:
For the ease of those skilled in the art's understanding, below in conjunction with embodiment and accompanying drawing, the present invention is further illustrated, and the content that execution mode is mentioned not is limitation of the invention.
As shown in Figure 1, a kind of multiband external antenna of architecture advances, comprise grounded metal pipe 1, coaxial line 2 and heat-shrink tube 3, further comprise a solid metal column 4, the inner wire 5 of described coaxial line 2 is connected with described solid metal column 4, the outer conductor 6 of described coaxial line 2 is connected with described grounded metal pipe 1, and one end of described heat-shrink tube 3 and grounded metal pipe 1 are socketed, and the other end of heat-shrink tube 3 and solid metal column 4 are socketed.
The present invention improves traditional dual-band antenna, utilize a real new metal column to substitute traditional spiral microstrip antenna, do not need screw type microstrip antenna can realize two frequency range work, the simple science of its structural design, not only there is better performance, and volume is little, cost is low, application is wide, practicality is very strong.
The material of the new metal column of reality of the present embodiment can be selected from the metal material that copper material, aluminium etc. are conventional.
Further, between described grounded metal pipe 1 and solid metal column 4, leave gap, described heat-shrink tube 3 is coated on the outside in this gap.
Suppose that wavelength corresponding to resonance frequency that described antenna produces is λ, the odd-multiple that the length of described solid metal column 4 is λ/4 is multiplied by the shortening coefficient of 3 losses of described heat-shrink tube, what the shortening coefficient of described heat-shrink tube 3 losses can be measured goes out, and generally its value range is 0.7-0.98.The length of described grounded metal pipe 1 is 9～23mm in the present embodiment, and the length of the new metal column of described reality is 13～25mm.
Finally should be noted that; above embodiment is only for illustrating technical scheme of the present invention but not limiting the scope of the invention; although the present invention is explained in detail with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify or be equal to replacement technical scheme of the present invention, and not depart from essence and the scope of technical solution of the present invention.
