Description
Technical field
The present invention relates to television antenna technical field, more particularly to a kind of novel wide-band double square loop antenna.
Background technology
The guided wave of the propagation on pipeline can be transformed into unbounded medium by antenna by it（Usually free space）In
The electromagnetic wave of propagation, or carry out opposite conversion, and being widely applied, wherein bandwidth as weigh antenna can effective work
The index of the frequency range of work, the size of its numerical value has a significant impact to the performance of antenna.Traditional antenna is by using
Thicker metal wire, metal cylinder mould and the bandwidth of antenna is improved using means such as the integrated single parts of a plurality of antenna, so
And there is the defects such as the structure of antenna excessively complicated or its performance is unstable in these modes.
At present, with the development of Modern wireless communication technology, various equipment propose higher wanting to the ability to accept of antenna
Ask, but existing antenna equipment all has that bandwidth is not big enough, governs the extensive use of television antenna, it is impossible to and satisfaction disappears
The need for the person of expense.Therefore, it is badly in need of a kind of appearance of the antenna that can realize ultrabroad band, solves the consumption demand of in the market.
The content of the invention
It is reasonable in design it is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of simple structure, can realize super
The novel wide-band double square loop antenna of work in broad frequency range.
To achieve the above object, technical scheme provided by the present invention is：A kind of novel wide-band double square loop antenna, bag
Insulated substrate and a rectangular becket being printed on the insulated substrate are included, the becket is rectangular by a pair
Inside and outside becket is constituted, wherein the side integrator of the inside and outside becket and be provided with a pair for feed current feed department,
The connection that intersected at its relative another side angle is formed with the aerial radiation loop portion for matching.
Further, the profile of the outer becket matches with the characteristic of low end frequency wavelength；The interior becket
Profile matches with the characteristic of high end frequency wavelength.
Further, the corner of the becket is rounded down.
After such scheme is employed, the double square loop antenna can be by its a pair by inside and outside rectangular gold for the present invention
Category ring constitute antenna realize worked in ultrabroad band wide scope, wherein the interior becket by with high end frequency wavelength characteristic
The shape and structure for matching is designed, realize its produce high end frequency signal radiation function, meanwhile, outer becket by with it is low
The contour structures that end frequency wavelength characteristic matches are designed, and realize that it produces low side high-frequency signal radiation function.And
And the aerial radiation loop for matching that the double square loop antenna is formed by the connection that intersects of its inside and outside becket side
The frequency that portion can more further improve abundant signal automatically selects path, effectively increases the bandwidth model of the double square antenna
Enclose, improve the return loss of antenna.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Fig. 2 is the dimensional structure diagram in the present invention.
Fig. 3 is the graph of a relation of the return loss value when present invention is emulated under frequency 470MHz to 860MHz and frequency.
Specific embodiment
With reference to specific embodiment, the invention will be further described：
Referring to shown in accompanying drawing 1 to accompanying drawing 2, a kind of novel wide-band double square loop antenna described in the present embodiment, the antenna
Including an insulated substrate 1 being made up of insulating materials, the upper surface center of insulated substrate 1 is printed with a rectangular metal
Ring 2, the wherein becket 2 are made up of a pair rectangular inside and outside beckets 202,201, specifically, the inside and outside becket
202nd, 201 bottom side is formed integrally, and the bottom side be additionally provided with a pair for feed current feed department 4, while the bottom
The relative opposite side in end side, i.e., inside and outside becket 202,201 is by the connection that intersected at its end angle described in the side of top
The aerial radiation loop portion 3 for matching is formed with, the aerial radiation loop portion 3 that wherein this matches is so that the radiant loop of antenna
Increase, then allow that antenna automatically selects suitable radiation path according to produced radiation signal, effectively raise
The bandwidth range of the antenna.Meanwhile, the interior becket 202 is entered by the shape and structure matched with high end frequency wavelength characteristic
Row design, realize its produce high end frequency signal radiation function, meanwhile, outer becket 201 by with low end frequency wavelength characteristic
The contour structures for matching are designed, and realize that it produces low side high-frequency signal radiation function, the double square loop antenna point
Not by high end frequency signal radiation function, the combination of low end frequency signal radiation function of its inside and outside becket 202,201,
The effective bandwidth range for expanding antenna, realizes broad-band antenna truly, enhances television antenna and TV is believed
Number ability to accept, the gain of antenna is improve, while being also correspondingly improved the quality for receiving television signals.The present invention in order to
Improve the performance and manufacturability of the antenna, the corner of the becket 2 is also rounded down.
It is of the invention when the wave band of frequency 470MHz to 860MHz is emulated referring to shown in accompanying drawing 3, its return loss value
Below -16dB, be can be seen that compared with traditional antenna from the simulated effect, the antenna significantly improves returning for antenna
Ripple is lost, and the efficiency of antenna is effectively improved.
, when test emulation is carried out in the wave band of frequency 470MHz to 860MHz, its standing-wave ratio, should all below 2 for the present invention
Invention effectively solves limitation of the bandwidth to television receiving antenna for a long time, realizes the reception energy of the ultrabroad band of antenna
Power.
The examples of implementation of the above are only the preferred embodiments of the invention, not limit implementation model of the invention with this
Enclose, therefore the change that all shapes according to the present invention, principle are made, all should cover within the scope of the present invention.
