It is obviously improved.
As seen from Figure 8, the impedance bandwidth of the antenna that embodiment three is proposed with comparative example one, comparative example two all compares
It is close, there are two obvious resonance points in working band, respectively appear at 7.6GHz and at 10.8GHz, therefore implement
, in the case where working band is not influenceed, than comparative example one and comparative example two more preferably, gain is higher for directionality for example three, and embodiment
The impedance operator of two antenna is due to the addition of metal patch, and change is relatively acutely, just humorous in master mainly due to metal patch
Shake the surface of medium, and the main operation modes to medium generate disturbance so that radiation characteristic is no longer symmetrical, i.e., directionality is more
Well, the side in the desired direction of radiation direction that energy can be concentrated more, that is, antenna, meanwhile, compared to former three, embodiment
Two antenna gain is higher.To antenna size, (main resonance medium is situated between embodiment one with resonance is guided on the basis of embodiment two
Spacing, both interior outer radial dimensions and height dimension between matter etc., are specifically shown in Table 1 with table 2) make optimization transfer, in addition
Quantity and position to metal column are optimized transfer, from fig. 6, it can be seen that the antenna available frequency band of embodiment one is
7.69GHz-11.61GHz, with a width of 3.92GHz, relative bandwidth is 40.6%, there is two obvious resonance points in band,
It is respectively 8.0GHz and 10.06GHz, the match condition in band is improved while having expanded bandwidth.
In order to further verify main resonance medium and guide the distance between resonator, dielectric, feed probes length and main resonance into
Influence of the medium internal diameter to antenna performance, present inventor further based on embodiment one, separately designs different
Main resonance medium from guide resonator, dielectric distance, different feed probes length and different main resonance medium inner radius values into, and
Emulation testing has been carried out to antenna, the S parameter scanning curve figure of Fig. 9~Figure 11 has been obtained.
Fig. 9 show main resonance medium and guides influence of the distance s 2 of resonator, dielectric to antenna impedance bandwidth into.From Fig. 9
As can be seen that spacing is not very big for the influence of bandwidth, the effect of matching is simply have impact on.In fact, spacing this parameter
For antenna it is critical that.When two media are away from too far away, the field of main resonance working medium radiation is guided into no arrival
Will decay before resonator, dielectric, the coupling of two media substantially diminishes, so that the effect of guiding into for guiding resonator, dielectric into is difficult to
Play；And when the distance between two media are too near, the directional diagram bandwidth of antenna apparent can diminish, in impedance bandwidth again
Indivedual frequency ranges on, the antenna pattern of antenna can occur bifurcated, therefore, in embodiment one choose s2 be equal to 9 when, antenna impedance
Matching is optimal.
Figure 10 shows the influence of the height to antenna operating band of feed probes.As can be seen that height increases to from 6mm
During 9mm, the impedance bandwidth of antenna is tapered into, and impedance matching is gradually deteriorated.Even if probe height is smaller at one
In the range of change, the working band of antenna can also occur violent change.In embodiment one when the height of probe is 6mm,
Impedance matching reaches most preferably.
It can be seen from fig. 11 that there are two resonance points, and main resonance medium inside radius r1 in working band in antenna
This parameter mainly influences the impedance matching property at high-frequency resonance point, main resonance medium inside radius to increase to from 1.0mm
During 1.6mm, the frequency band of antenna is overall to be moved to high frequency treatment, when main resonance medium inside radius is equal in embodiment one
During 1.0mm, impedance matching is optimal.
The preferred embodiments of the present invention are the foregoing is only, is not intended to limit the invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.It is all within the spirit and principles in the present invention, made any repair
Change, equivalent, improvement etc., should be included within the scope of the present invention.
