Embodiment
For above-mentioned and other purposes, feature and advantage of the present invention can be become apparent, cited below particularlyly go out specific embodiments of the invention, and cooperate appended accompanying drawing, be described in detail below.
Please refer to Fig. 2, Fig. 2 is the schematic diagram of the compensation antenna of the present invention.
Compensation antenna 10 of the present invention is a flat structure, and is arranged on the substrate 11.Compensation antenna 10 comprises radiation assembly 20, grounding assembly 30, resonance assembly 40, load point F and earth point G.Substrate 11 is a kind of printed circuit board (PCB), plastic plate or glass mat, but the present invention is not as limit.The edge shape of the radiation assembly 20 of wherein compensation antenna 10, grounding assembly 30 and the form fit substrate 11 of resonance assembly 40 on the same plane that is printed in substrate 11, perhaps utilizes ironware to make to be attached at the same plane of substrate 11 again.
Radiation assembly 20 can be by electric current with the exciting radiation energy.Wherein radiation assembly 20 comprises first radiation areas 21, second radiation areas 22 and the 3rd radiation areas 23, wherein first radiation areas 21 and second radiation areas 22 are connected to each other, second radiation areas 22 and the 3rd radiation areas 23 are connected to each other, to form the structure of similar loop-type antenna.When load point F feed-in electrical signals, compensation antenna 10 can be with electrical signals through first radiation areas 21, second radiation areas 22 and the 3rd radiation areas 23 thus to form signal circuit, to produce a certain amount of magnetic field radiation energy.
Grounding assembly 30 is in order to the usefulness of formula antenna 10 ground connection by way of compensation, and the scope of grounding assembly 30 can be the substrate 11 of full wafer, to strengthen the ground connection scope.And in the present embodiment, grounding assembly 30 comprises first ground area 31, second ground area 32 and the 3rd ground area 33.First ground area 31 and second ground area 32 be vertical connection in fact, and the 3rd ground area 33 then joins with radiation assembly 20.But grounding assembly 30 of the present invention does not exceed with above-mentioned shape.
Resonance assembly 40 extends out from grounding assembly 30.Resonance assembly 40 comprises first resonance zone 41 and second resonance zone, 42, the first resonance zones 41 and second resonance zone 42 vertical connection in fact.And first resonance zone 41 and second radiation areas 22 are parallel to each other in fact, and second resonance zone 42 and the 3rd radiation areas 23 are parallel to each other in fact.Resonance assembly 40 is by producing the effect that resonates with radiation assembly 20, to form effective radiant body.Thus, compensation antenna 10 is able to the exciting radiation energy.And the working frequency range of compensation antenna 10 can be adjusted by the length of resonance assembly 40, and the length of extending when first resonance zone 41 of resonance assembly 40 is long more, and compensation antenna 10 can have lower working frequency range.
On compensation antenna 10, also comprise a load point F and earth point G.In an embodiment of the present invention, load point F is positioned on the 3rd radiation areas 23.Load point F electrically connects a feed-in line (scheming not formula), in order to the feed-in electrical signals.The feed-in line can be the cable as RF cable (RF Cable) etc., but the present invention is not as limit.Earth point G then is positioned on the grounding assembly 30, and electrically connects by feed-in line and load point F, with the usefulness as signal ground.Its earth point G can be positioned at the ground connection scope that grounding assembly 30 is strengthened, but the present invention is not as limit.When electrical signals during via load point F feed-in, the effect by resonance assembly 40 produces resonance coupling with the structure of radiation assembly 20 makes compensation antenna 10 be able to the exciting radiation energy.
Then please refer to Fig. 3, Fig. 3 is according to Fig. 2, shows that it is in the dB of different frequency value.
By among Fig. 3 as can be known, compensation antenna 10 is by the effect of above-mentioned structure and resonance, but if being the working range of antenna less than negative 9.54dB value, can transmit 2.3GHz arrives near the frequency range about 2.6GHz, not only can meet the required 2.4GHz of Bluetooth system to transmission band, also can be used for the usefulness of other communications near 2.5GHz.
Then please also refer to Fig. 4 A to Fig. 4 C and Fig. 5 A to Fig. 5 C, about compensation antenna in level and vertical direction the radiation pattern figure under different frequency, wherein Fig. 4 A-Fig. 4 C is according to Fig. 2, show its (Phi=0) radiation pattern figure under 2.4GHz, 2.45GHz and 2.5GHz in the horizontal direction respectively, Fig. 5 A-Fig. 5 C is according to Fig. 2, shows that respectively it is at the radiation pattern figure of vertical direction (Phi=90) under 2.4GHz, 2.45GHz and 2.5GHz.
Can learn that to Fig. 4 C and Fig. 5 A the radiation pattern figure of compensation antenna 10 can form the antenna of a directive property by Fig. 4 A to Fig. 5 C, make the energy of radiation more concentrate on same direction.
By the structure of above-mentioned compensation antenna 10, can reach the efficiency of transmission about 40% to 60%.And because compensation antenna 10 cooperates the shape of substrate 11, therefore can be arranged at substrate 11 discarded useless positions, can reduce about cost more than 50%.
At last, please refer to Fig. 6, about the system block diagram of electronic installation of the present invention.
In one embodiment of this invention, electronic installation 50 can be mobile devices such as mobile phone or PDA, but the present invention is not as limit.As shown in Figure 6, electronic installation 50 of the present invention comprises compensation antenna 10 and wireless signal module 51.Electronic installation 50 can utilize feed-in line (figure does not show) to be fed into compensation antenna 10 and electrically connect with wireless signal module 51, to handle the signal of compensation antenna 10 by wireless signal module 51, for example launches or received signal.Thus, electronic installation 50 promptly can receive or transmit the device (figure do not show) of wireless signal to other by compensation antenna 10, to reach the purpose of radio communication.
To sum up institute is old, and no matter the present invention everywhere all shows it totally different in the feature of known technology with regard to purpose, means and effect, earnestly asks the auditor to perceive, and grants quasi patent early, makes Jiahui society, and the true feeling moral just.Only it should be noted that above-mentioned many embodiment give an example for convenience of explanation, the present invention's interest field required for protection should be as the criterion so that the scope of claims is described naturally, but not only limits to the foregoing description.
