Abstract
The utility model discloses a multiple frequency antenna, comprising a left and right extending retention part, wherein one flank of the retention part extends to form a connection part and the end of the connection part extends towards one end to form a low frequency radiation part and another end of the connection part extends towards another end to form a low frequency radiation part. An extension part extends downside at one position of the retention part corresponding with the outside of the high frequency radiation part and a resonance radiation part extends outside at the position of the flank of the extension part corresponding with the high frequency radiation part, and the length of the resonance radiation part is equal to the length of the high frequency radiation part. The multiple frequency antenna can generate resonance with the high frequency radiation part because the length of the resonance radiation part is equal to the length of the high frequency radiation part, thus the receiving and sending effect of the electromagnetic signal of the same waveband can be increased.

Technical field
The utility model relates to a kind of multifrequency antenna, relates in particular to a kind of multifrequency antenna that is used on the super portable computer (UMPC, Ultra-mobile Personal Computer).
Background technology
A kind of multifrequency antenna as shown in Figure 2, it comprises the holding parts 20 that extends about, earlier oblique the extension down extends to form a junction 21 more left at the lateral margin middle part of holding parts 20, the left side edge of connecting portion 21 tail ends extends to form a high-frequency radiation part 23, and the right side edge of connecting portion 21 tail ends extends to form a low frequency radiation portion 24.This low frequency radiation portion 24 and high-frequency radiation part 23 can be received and dispatched the electromagnetic signal of 2.4GHz and 5.2GHz respectively.
Along with the raising of current people to the signal transmitting and receiving usefulness requirement of super portable computer, the structure of the existing antenna of improvement, the transmitting-receiving usefulness of enhancing signal become new demand, and above-mentioned multifrequency antenna usefulness is lower, is difficult to satisfy this requirement.
The utility model content
The purpose of this utility model is to provide a kind of higher multifrequency antenna of usefulness of receiving and dispatching electromagnetic signal at the defective that prior art exists.
For reaching above-mentioned purpose, the utility model multifrequency antenna has the holding parts that extends about, one lateral margin of holding parts extends to form a junction, one lateral edges of connecting portion end extends to form a low frequency radiation portion to a side, and the opposite side edge of connecting portion end extends to form a high-frequency radiation part to opposite side; Position corresponding to the high-frequency radiation part outside on the holding parts extends to form an extension downwards, and extension has extended to form a resonance Department of Radiation laterally corresponding to the position of high-frequency radiation part, and resoance radiation portion is suitable with the length of high-frequency radiation part.
As mentioned above, the utility model multifrequency antenna since on extension, increased by one with the length suitable resoance radiation portion of high-frequency radiation part, and resoance radiation portion can resonate with high-frequency radiation part, thereby can increase the transmitting-receiving usefulness of corresponding wave band electromagnetic signal.

Embodiment
For describing technology contents of the present utility model, structural feature, the purpose that is realized and effect in detail, give explanation below in conjunction with specific embodiment and conjunction with figs. are detailed.
See also Fig. 1, the utility model multifrequency antenna 1 has a holding parts, and this holding parts comprises about one the baseplate part that is strip 10 that extends, these baseplate part 10 ground connection, and the forward edge of baseplate part 10 bends vertically downward and extends to form a bending part 100; Here holding parts might not be the shape that is made of orthogonal bending part 100 and baseplate part 10, also can be other shape of being convenient to install and fix.Again be parallel to bending part 100 after the also downward-sloping extension in the middle part of these bending part 100 lower edge left and extend to form one first connecting portion 11, the end of first connecting portion 11 is provided with a load point 110, and forms simulaed inductance between first connecting portion 11 and the bending part 100.The terminal lateral margin of first connecting portion 11 extends to form one second connecting portion 12 downwards, second connecting portion 12 and first connecting portion 11 are formed connecting portion 19, connecting portion 19 is not limited to be made up of first connecting portion 11 and second connecting portion 12, can also be for satisfying other structure of its function.The left side edge that the right side edge of these second connecting portion, 12 ends extends to form low frequency radiation portion 14, the second connecting portions, 12 ends of a strip to the right extends to form the high-frequency radiation part 15 of a strip left.Protrude out formation one fixed part 17 downwards in low frequency radiation portion 14 right-hand members on this bending part 100; And extend to form an extension 13 downwards in the position in the high-frequency radiation part 15 left ends outside on the bending part 100.Offer a fixing hole 18 on extension 13 and the fixed part 17 respectively, by this two fixing hole 18, the utility model multifrequency antenna 1 can be provided with on the shell (not shown) that is fixed in super portable computer.The left border of this extension 13 extends to form the resoance radiation portion 16 of a strip left corresponding to the position of high-frequency radiation part 15.
The length of described low frequency radiation portion 14 is the electromagnetic quarter-wave of 2.4GHz, the electromagnetic signal that can receive and dispatch 2.4GHz; The length of this high-frequency radiation part 15 is the electromagnetic quarter-wave of 5.2GHz, the electromagnetic signal that can receive and dispatch 5.2GHz.The length of this resoance radiation portion 16 is suitable with high-frequency radiation part 15, be all the electromagnetic quarter-wave of 5.2GHz, can receive and dispatch the electromagnetic signal of 5.2GHz, and because its length is suitable with high-frequency radiation part 15, so resoance radiation portion 16 can resonate with high-frequency radiation part 15, increase the transmitting-receiving usefulness of the electromagnetic signal of 5.2GHz.
From the above mentioned, the utility model multifrequency antenna 1 since increased on the extension 13 one with the suitable resoance radiation portion 16 of length of high-frequency radiation part 15, and resoance radiation portion 16 can resonate with high-frequency radiation part 15, therefore can increase the transmitting-receiving usefulness of 5.2GHz wave band electromagnetic signal.
