Description of the Invention: [Technical Field] The present invention relates to a slot antenna, and more particularly to an antenna structure having a dual-frequency single-phase aperture. [Prior Art] Most of the slot antennas currently designed are in the form of single slots. They are designed as single-frequency systems, so they can only operate in a wireless LAN system in a single frequency band. There are many improvements in the structure proposed. Figure j is a top view of a conventional dual-frequency slot antenna, comprising: an elongated metal piece 1〇, a longer-shaped slot n, a shorter one (4) Wei 12, a feed. 3. A first-ground point 14 and a second ground point 15; a longer one of the Φ slots 11 formed in the elongated metal sheet for generating a first (low frequency) operating mode of the antenna The shorter one-shaped slot 12 is formed in the = long gold, the poem produces the second (high frequency) operation 2 of the antenna; the feed point 13 is located in the longer-shaped slot 11 and the shorter one - Word 7 曰 12 between the 'first-ground point 14 is located in the longer - glyph slot I] outer edge 111, the first from the ground point is located on the outer edge of the shorter-shaped slot 12 12 _ the frequency and the length of the two n-slot holes, get the appropriate resonance;; ratio, adjust the feed point 13, first Location 14 and the grounding point of the 1 5 position;; not 丨ή and 5. 2GHz dual-frequency antenna in the / impedance matching, designed by this 2, 4, Huai eight antenna must have one of two different sizes of bandwidth The process is complicated, and the system generates the dual frequency. Please refer to the 2nd S!, & σ picture is a perspective view of another conventional dual-frequency slot antenna. 200905987 The dual-frequency slot antenna 2 is mainly composed of a conductor. The conductor is provided with two different lengths of the first slot 21 & the second slot 22, by forming a first resonance frequency at the first slot 21 when the signal is fed at the feed point 23 Transmitting and transmitting 汛唬 'when fed by another signal' can be coupled to form a resonance at the second slot 22 and generate another-transmission signal' using a combination of two sets of slots to achieve a dual-frequency resonance effect, thereby transmitting and receiving two Different frequencies. However, the slots provided by the conductors 2 must be at a specific angle to each other to produce a better resonance frequency, which increases the difficulty of manufacturing the product, and it does not reliably achieve the effect of wide frequency. In view of the shortcomings of the conventional slot antenna technology, the researchers are actively aiming at simplifying the structural complexity of the slot configuration, and at the same time having multiple operating frequency bands, and providing better frequency ratio and impedance bandwidth improvement problems. SUMMARY OF THE INVENTION An object of the present invention is to provide a slot antenna that utilizes a first conductor, a second conductor 'feeding line, and a grounding portion to form a simple dual-frequency single-slot antenna structure. The first conductor passes through the second conductor. The conductor excitation produces a first resonant mode and the second resonant mode is generated by the feed conductor itself, improving the conventional single slot to only produce a single operating frequency deficiency. Another object of the present invention is to provide a slot antenna, wherein a gap is formed on a side of a first conductor via the missing σ, a matching conductor in the second conductor, and a feed point to which the feed line is connected to the feed conductor for adjustment The impedance matching of the first and second resonant modes increases the operating bandwidth of the antenna. Another object of the present invention is to provide a slot antenna, an extension conductor is extended on the side of the first conductor, and the slot conductor is used to adjust the slot width of the slot 200905987. The bandwidth is insufficient to avoid generating the slot antenna. Problem 0: To achieve the above object, the first embodiment of the present invention is a slot-hole connection: f, including: - a first conductor, a second conductor, a feed line, and a 邛 '5 Xuan-conductor - The slot is slightly c-shaped, including the side of the mouth, the side of the right side, the upper side and the lower side, and the second conductor is disposed on the side of the first conductor and is disposed in the slot of the first conductor Including long strips = feed conductors and matching conductors, matching conductors - the ends are connected to the feed guide 'the other end extends to the vicinity of the gap and is spaced from the first conductor - the feed line contains - the center conductor and - The outer conductor 'where the center guide-, forms a feed point on the surface of the feed conductor, and the outer conductor is connected to the surface of the conductor-conductor; the ground portion is connected to the side of the first conductor. The antenna structure configured by using the first conductor is mainly generated by the excitation of the feeding conductor by the first conductor, and the center frequency of the first resonance mode is changed by using the size of the slot; And generating a second resonant mode by feeding the conductor itself, the length of the feeding conductor can control the heart frequency of the second resonant mode; the distance between the first conductor and the matching conductor is - gap, so the ratio can be generated a capacitive effect, and the matching conductor generates an inductive effect, which can be used to adjust the impedance matching of the first resonant mode; the feed two-point setting can be used to adjust the input impedance of the second resonant mode, and The grounding portion can increase the area of the ground plane of the slot antenna, so that the bandwidth of the slot antenna is increased. In addition to simplifying the antenna structure, the above structure simplifies the single-slot antenna structure to only produce a single operating frequency loss. Text. The operation principle of the second embodiment of the present invention is the same as that of the first embodiment. The difference between the two and the second embodiment is that the conductor on the side of the first conductor is extended with the conductor-end of the first conductor, and the other is the conductor. The end portion is further away from the first guiding rhythm, but the end thereof needs to be turned into a f-curve and close to the first-conductor, and the spot-carrying capacitance fits the effect. The capacitance-consuming effect can be used to adjust the impedance of the slot antenna system. The _m-slot antenna n卩 and the anti-change is more =, the effect increases the impedance bandwidth of the slot antenna system, thereby increasing the operating bandwidth of the antenna system band. In summary, the dual-frequency single-slot antenna of the present invention can generate a (four) common state via the first conductor and the feed conductor, and the improved single-frequency single-slot antenna structure can only produce a single operating frequency loss and improve at the same time. The dual-frequency dual-slot antenna must be configured with the structure limitation of the double-slot hole, and the first conductor 2 notch, the matching conductor and the ore point setting can be used to adjust the antenna to the optimal impedance matching, and then the impedance of the antenna system is adjusted by the extension conductor. The bandwidth makes the dual-frequency single-slot antenna of the present invention have better impedance bandwidth than the dual-frequency dual-slot antenna' and its composition is simplified. To further clarify the details of the present invention by the reviewers, the following description of the preferred embodiments is set forth below. 3 is a top plan view of a first embodiment of the present invention, the slot antenna device includes: a first conductor 31, a second conductor 32, a feed line 33 and a grounding portion 34; The first conductor 31 includes a slot 311 and is slightly C-shaped, including a left side 313, a right side 315, an upper side 317 and a lower side 319, and a notch is provided on one side of the first conductor 31. 312. In this embodiment, the notch 312 is disposed on the left side 312 and is adjacent to the bottom side 319 of the 200905987. The length of the long side of the first conductor 31 is about 35, and the length of the short side is about 9 mm. The width of the first conductor 31 itself is about 2; the length of the slot is about 29, the width is about 5 mm, and the length of the notch is about 3 mm; The first conductor 32 is located in the slot 311 of the first conductor 31 and includes a long strip-shaped feed conductor 321 and a matching conductor 322. The matching conductor 322 - the end is connected to the feed conductor 32. Up to the gap 3丨2 and a gap from the first conductor 31, the feed conductor 321 has a length of about 14 mm and a width of about 1.5 mm, the matching conductor 322 has a length of about 1 mm, and the width is about m matching 'body 322. The gap between one end of the vicinity of the notch 312 and the first conductor 31 is about 1 mm; the feed line 33 includes a center conductor such as an outer conductor 332, wherein the center conductor 331 is connected to the surface of the feed conductor 321 and forms a feed. Point 333, and the outer conductor 332 is connected to the surface of the first conductor 31; the ground portion 34 is a metal foil and is attached to the side of the first conductor 31. In the embodiment, the ground portion 34 and the bottom The side edges 319 are connected but may also be connected to the upper side 317. The slot antenna structure configured in this manner mainly utilizes the excitation of the first conductor 31 to generate a first-resonance mode by the excitation of the feed conductor 321, and generates a second resonance mode by feeding the conductor 321 itself. The position and width of the notch 312 of a conductor I are set, and the position of the matching conductor 322 relative to the notch 312 is controlled, thereby adjusting the impedance matching of the first resonant mode, and the adjusting feed point 333 is located on the surface of the feeding conductor 321 The manner of setting, so that the impedance matching of the second resonant mode of S is completed, so that the overall slot antenna structure has better impedance matching, thereby improving the operating bandwidth of the antenna system band. 200905987 The first embodiment of the present invention utilizes the first conductor 31, the second conductor 32, the feed line 33 and the grounding portion 34 to form a simple dual-frequency single-slot antenna structure. The modified single-frequency single-slot antenna structure can only produce a single The lack of operating frequency 'At the same time, the improved dual-frequency dual-slot antenna must be configured with the structure limitation of the double-slot, and the first and second resonances can be adjusted by using the gap of the first conductor 31, the matching conductor 322 and the feeding point 333. Modal to optimal impedance matching simplifies the complexity of antenna structure combination, increases product mass production speed, and breaks through the limitations of the prior art. Referring to FIG. 4 and FIG. 5, the feed conductor 321 can also be disposed in a -3⁄4. fold shape, and the matching conductor 322 is disposed in the form of a ,, which can change the inductance effect thereof, and the gap 312 of the side of the first conductor 31 is The matching conductors 322 have a gap between them, and the capacitance effect is changed by controlling the gap width, thereby adjusting the impedance matching of the first resonant mode, and also generating an electrical coupling effect through the gap, thereby increasing the slot 311 of the first conductor 31. Internal radiation conduction efficiency. In this embodiment, the width of the notch 312 of the first conductor 31 should not be too large. If the notch 312 is too large, the first conductor 31 will not be easily excited to generate the first resonant mode. The notch 312 can be disposed on one side of the left side 313, the right side 315, the upper side 317, and the bottom side 319 of the first conductor 31, but not at the same side of the ground portion 34, and its position Not limited. In other words, the grounding portion 34 is connected to one side of the first conductor 31 which is different from the one of the notch 312. "Monthly referring to Fig. 6, the return loss measurement data according to the first embodiment of the present invention is not intended to be 'the antenna operating frequency is in the case of a return loss of - brain condition' bandwidth > about 2, 2 (operation The frequency range covers 3. to 200905987 6GHz) 'This bandwidth application range will cover uwB: 3i7〇~6〇〇〇MHz system bandwidth, showing the first conductor 31 and the second conductor 32 set in this way The wider range of operating bandwidths in the composite system range, as well as better impedance matching, improves the lack of bandwidth limitations of conventional single- and dual-slot antennas. Please refer to FIG. 7 , which is a top plan view of a second embodiment of the present invention. The operation principle of the second embodiment of the present invention is the same as that of the first embodiment, and the difference is that the σ 312 is set relative to the first conductor 31 . - the opposite side extension ax of the side is placed with an extension conductor 35, one end of which is connected to the first conductor 3 and the other end extends in a direction away from the first conductor 31, and the end thereof must be bent and close to the first a conductor 31, thereby creating a capacitive coupling effect with the first conductor 31, the capacitive coupling effect can be used to adjust the impedance of the slot antenna system to make the impedance change more gradual and close to q ohms, effectively increasing the slot hole days, (4) The impedance bandwidth is used to improve the impedance bandwidth adjustment efficiency. The ground portion 34 is connected to the side of the first conductor 31 which is different from the gap 312 and the extension conductor 35. The above implementation relies on the extension mode % of the extension conductor 'in addition to the gap 312, the matching conductor 322 and the feed point 333 to adjust the antenna impedance matching, and the extension conductor 35 adjusts the impedance bandwidth of the antenna system' to make the overall slot antenna structure have Better impedance matching and operating bandwidth for a wider range of operating frequency systems. Referring to Fig. 8, there is shown a schematic view of a variation of an extension conductor according to a second embodiment of the present invention. When the extension conductor 35 extends from the opposite direction k of the first conductor 31, the bottom side 319 of the first conductor 31 extends toward the end of the extension conductor π, so that the extension conductor 35 is constructed similarly to the first conductor 31. In the present embodiment, the first conductor 31 and the extension conductor, that is, the structure, are mirrored by the right side 315 of 12 200905987. Therefore, by improving the impedance bandwidth adjustment efficiency of the extension conductor 35 for the overall slot antenna system, it is also possible to generate an electrical coupling effect through the gap between the two conductors, thereby increasing the internal slot 3 11 of the first conductor. Radiation conduction efficiency. 1 is a schematic diagram of return loss measurement data according to a second embodiment of the present invention, wherein the antenna operating frequency is about 5.5 GHz when the return loss is - deleted (the operating frequency range covers I). · Jobs), this bandwidth application range will cover GPS: 1575 MHz, DCS: 1710 ~ 1880 MHZ, PCS: 1850 ~ 199 〇 MHz, UMTS: 192 〇 ~ 2i · ^ WLAN 802. llb / g : 2400- 2500 MHz UWB: 3170-7000 MHz system bandwidth, showing the dual-frequency single-slot antenna structure set in this way, the bandwidth of the system frequency band has been significantly expanded, and also has better impedance matching and operating bandwidth And its composition is also simplified. Referring to FIG. 10, a second embodiment of the present invention is applied to a portable electric Hungarian 3. The slot antenna structure is attached to the edge of the bottom plate 37 of the portable computer 3, and the grounding portion 34 is also attached.
