Embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 2, be the one preferably execution mode of the present embodiment, a kind of PCB router antenna, comprises radiating doublet 1, ground area 2, connecting line 3, coiling 4 and PCB5.Radiating doublet 1, ground area 2 and coiling 4 are arranged on PCB5, and one end of radiating doublet 1 is electrically connected with coiling 4, and the other end is electrically connected with extraneous power supply (not shown) and connecting line 3, and ground area 2 is connected with extraneous power electric.
Particularly, radiating doublet 1, ground area 2 and coiling 4 are for being covered in the copper sheet on PCB5, and coiling 4 entirety is wavy in continuous print rectangle, thus can reach the effect of helicon.Optimally, the number of turns of coiling 4 is 8.5 circles, and the width of coiling 4 is 0.7mm, and stitching wide is 0.7mm.
Above-mentioned connecting line 3 is coaxial line, and it comprises conductor 31 and is wrapped in the ground connection braid 32 of conductor 31 periphery, and conductor 31 is electrically connected with radiating doublet 1, and ground connection braid 32 is electrically connected with ground area 2.
Above-mentioned radiating doublet 1 comprises radiant body 11, and the length of radiant body 11 is identical with the length of ground area 2.
The PCB router antenna of the present embodiment also comprises plastic cement loop bar (not shown), above-mentioned radiating doublet 1, ground area 2, coiling 4, PCB5 and part connecting line 3 are all arranged in plastic cement loop bar, and the current existing WLAN5dBi on the market of the optional use of this plastic cement loop bar overlaps the plastic cement loop bar of spike antenna.
For the design principle of the PCB router antenna of the present embodiment is as follows:
Wire has alternating current by time, electromagnetic radiation can occur, radianting capacity is relevant with conductor length and shape.When two wires are very near, electric field is strapped between two wires, and radiation is very faint.But when two wires open, electric field is just spread out in surrounding space, radiation intensification.When the length L of wire can follow wavelength X comparable time, wire conductance current becomes large, and radiation is just stronger.
Half-wave dipole is made up of the straight wire that two diameters are all equal with length, and each wire is 1/4 length of operation wavelength, diameter of wire << λ.(calculating of antenna length: L=λ/4=c/4f, c are the light velocity in vacuum, f is operating frequency.)
The PCB router antenna of the present embodiment extends in above-mentioned principle, and λ/4 radiation conductor increases the wavy resonance cabling of rectangle, and the gain that improve PCB router antenna is mated with port Impedance.
Utilize high-frequency structure to emulate (High Frequency Structure Simulator, HFSS) and carry out emulation confirmation PCB router antenna performance: first determine that PCB5 size is 7.6*125*0.8mm according to the plastic cement size of the external cover spike antenna of the general 5dBi in current market; Then radiant body 11 length roughly 30mm is determined by working frequency range 2.4G ~ 2.5G.Because PCB5 dielectric property can shorten the length of radiant body 11, so tentatively fix on 25mm, similarly, the length of ground area 2 is also 25mm.
Can show that PCB5 surface current is except except the distribution of feed point from simulation result, main integrated distribution is at coiling 4 upper area.Coiling 4 forms gap electric field between each gap, and alternating electric field forms magnetic field to space radiation electromagnetic energy, thus strengthens the radianting capacity of PCB router antenna, improves the gain of PCB router antenna.
Radiating doublet 1, earth connection 2 and coiling 4 are arranged on PCB5 by the PCB router antenna of this enforcement, instead of the structures such as the screw rod of traditional antenna, copper pipe, simplify production process, also save material cost simultaneously.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
