Line is the focus of Developing, and in small hand held devices, the design of PIFA receives the accreditation of each side.
PIFA antenna is developed by IFA antenna.For IFA, there is higher Q-value and narrower bandwidth, by
It is thin wire so that the distribution capacity small inductor of equivalent radio frequency is big in its radiating element and earth lead.After making improvement, will
Thin wire changes the sheet metal of width into, makes electric capacity increase inductance and reduces, reduces Q-value, also make bandwidth be increased, and this is just
Become PIFA antenna.
The method realizing multifrequency has orthogonal mode, many pasters, lamped element to load, gap loads (surface fluting) etc..Table
Face fluting is the most simple and practical, and the shape of fluting is varied, such as L-type, U-shaped, T-shaped, cross etc..And about this side
Face research there is also many defects, such as Xu Na et al. " planar inverted F three-frequency mobile phone antenna in conventional design
Design " in mention and utilize dual U-shaped groove to obtain 2.45GHz, but structure is relatively complicated.Therefore a kind of simple in construction is designed
Multifrequency antenna has the meaning of more reality.The 1GHz antenna being currently used for aviation also needs to study further, is radiated by improvement
Patch shape can reach required frequency range.
Summary of the invention
This utility model relates to a kind of flag-shaped isometric L-shaped groove dual-band antenna, simple in construction, it is easy to processing.Pass through coaxial feed
Line feeds, and uses the radiation patch structure of flag-shaped isometric L-shaped groove, and loads short-circuiting jumper, it is achieved that impedance matching
Characteristic, effectively reduces the return loss of operating frequency range, adds bandwidth.
This utility model adopts the following technical scheme that
This utility model flag-shaped isometric L-shaped groove dual-band antenna includes radiation patch 101,102, L-shaped groove 201, coaxial feeder
301, short-circuiting jumper 401, ground plane 501, it is characterized in that: 101,102 two rectangles of described radiation patch connect in flag
Shape, in radiation patch, L-shaped groove 201 is to be made up of long and wide two equal rectangular channels.Described coaxial feeder 301 and short circuit gold
Belonging to 401 to be connected with ground plane 501 with radiation patch 101,102, coaxial feeder 301 and short-circuiting jumper 401 are on the side.Institute
The radiation patch 101,102 stated is parallel with ground plane 501.
This utility model compared with prior art, has a following remarkable advantage:
1, simple in construction: this utility model simple in construction, it is easy to processing；
2, frequency range is adjustable: this utility model uses flag-shaped equilateral L-shaped groove paster structure, is adjusted by the length and width changing flag-shaped
Frequency, the length and width changing L-shaped groove adjust higher frequency.

Detailed description of the invention
Below in conjunction with example and accompanying drawing, the utility model is described in further detail.
As it is shown in figure 1, rectangular radiation patch 101 and 102 combination presents flag-shaped structure, and open in radiation patch 101
Going out an isometric L-shaped groove 201, the rectangle that this groove is long by two and width is equal is constituted.Thus constitute flag-shaped isometric L-shaped groove double frequency
The radiation patch part of antenna.Label 101 is the big rectangle of radiation patch, and its length and width size is 45mm × 36mm, and label 102 is
The little rectangle of radiation patch, its length and width size is 8mm × 9mm, and the length and width size being opened isometric L-shaped groove is 27mm × 2mm.With
The feeder shaft 301 distributing point in radiation patch 101 is positioned on the left of radiation patch.
As in figure 2 it is shown, ground plane 501 is paralleled with radiation patch 101,102, the wide high size of short-circuiting jumper 401 is
6mm × 10mm, top is connected with radiation patch, and lower section is connected with ground plane.The radius of coaxial feeder 301 is 0.25mm, its
The positional distance radiation patch 101 left margin 5mm of distributing point, top is connected with radiation patch 101,102, lower section and ground plane
501 are connected.Ground plane 501 length and width size is 120mm × 55mm, nothing between radiation patch 101,102 and ground plane 501
Filled Dielectrics.
If Fig. 3 is the back view of this example, representing the ground plane 501 of antenna, coaxial feeder 301 is at ground plane 501
On feed position distance ground plane left margin 10mm.
If Fig. 4 is the return loss plot figure of this example, as can be seen from the figure this antenna at 0.94GHz-1.1GHz and
2.44GHz-2.48GHz the return loss in frequency range is respectively less than-10dB.
Such as Fig. 5,6 be the present embodiment directional diagram when 1GHz and 2.45GHz respectively, it can be seen that the present embodiment this two
There is in individual frequency range preferable omnidirectional characteristic, meet design requirement.
Examples detailed above is this utility model preferably embodiment, additionally on the basis of the present embodiment, changes radiation single
Unit, the position of coaxial feeder and the size of ground plane and size, all should be included in protection domain of the present utility model.
