This will make the antenna structure of communication products must be limited to a certain volume. If the design of the communication product has a structure with more than two antennas and the dual antenna is placed in a limited m, the distance between the antenna and the antenna will be very close.

The continuation 'as shown in Fig. 2' is a schematic diagram of the current path of the antenna structure which can improve the isolation between short-distance antennas. As shown, the first antenna 10 includes a -first current path 161 and a second current path 163, and the second antenna 30 includes a third current path 361 and a four current path 363. The first current path 161 of the first antenna 10 has a current system of a first > 64 点 person point li, a trapezoidal portion ” a connecting section 17, a first Π 15 and a 161. The first Fa1 has a The first current path of the first operating band reads the eight points "~the second current path 163' of the antenna 1() begins with the first light band and flows through the first adjustment segment 19 to produce a second Falling into the current path 163.

The second path 122, the third groove 123, the second groove 123, and the second area and the long acoustic groove 321 and the sixth groove 322 of the antenna antenna 30 may be adjusted. The seventh groove milk path 363 changes the second current _ 163 and the fourth current path step adjusts the length again. In this way, the antenna structure of the present invention will just enter the first operational frequency band and the second operational frequency band which are actually required. In the autumn, the isolation slot 23 described in Figure 1 of the skirt can be a hollow portion. As shown in Fig. 2, the isolation slot 23 of the present invention can also be optionally provided with a reinforcing 231 or a non-conductive material (for example, a plasticized material), thereby tying the isolation between the antennas. 1-Reading Fig. 3 is a structural diagram of another embodiment of the present antenna structure. The advantages and disadvantages of antenna radiation efficiency, one of which depends on the '^ antenna will open on the dielectric material = a resonant cavity when receiving or transmitting wireless signals. If the antenna is placed on a dielectric material with a higher dielectric constant, the radiation efficiency will be reduced. Conversely, if the antenna is placed on a dielectric material with a lower electric constant, the radiation efficiency of the antenna will be relatively improved. In order to achieve the effect of integrating the body, the antenna structure (100) of the brother 1 is a small-sized and lightweight antenna, and the antenna structure (10) is directly laid on the substrate 5, and the substrate 5 of the glass fiber is generally used. The dielectric constant of 〇 is generally referred to as M349564. However, the antenna structure 200 of the present embodiment can also provide the radiation surface of the first antenna 10, the first feed point 11, and the second antenna in order to improve the radiation efficiency of the antenna. A portion of the substrate of the radiating surface 30, the second feeding point 31, and the grounding surface 21 is removed to form a hollowed out state, and the isolation slot 23 at this time may be selected as a hollow portion. After the antenna structure 200 removes part of the substrate 50, when the antenna structure 200 receives or transmits a wireless signal, a resonant cavity is formed on the air.

由於空氣的介電常數較低(大約為1),藉此將大幅提高天線 結構200的輕射效率。 當然^本創作天線結構200為了提高天線間的隔離度 ,亦可如第4圖所示,在隔離槽孔23中選擇設置有一泡 棉31或非導電材料(例如:塑化材料),如此以避免天 線間之個別的無線訊號相互干擾。 請參閱第5圖及第6圖,係為一未設置有隔離槽孔之 =線^構之穿透損耗圖及—設置有隔離槽孔之天線結構之 穿透損耗圖。 本創作天線結構對於四個頻率點以2.4GHz)、 2.(2.5GHz) > 3 (λ ο-η Λ4.9〇Ηζ)及4.(5.8GHz)進行S參數測量的動 如第5圖所示, 帶曲線的四個頻率點 及-22db。 未設置有隔離槽孔的天線結構,在頻 所測得S參數約為-8db、-9db、-19db 而如第6 & - ^ ... 圖所不’設置有隔離槽孔的天線結構’在頻 ▼曲線的四個頻率點所測得S參數約為损b、-16db、- 12 M349564 21db 及-33db。 由上測1的S參數可知,加人隔離槽孔的天線結構(第 6圖)在各個頻率點所測量出的s參數的此值都比未設置 有隔離槽孔的天線結構(第5圖)還要低,此即代表加入隔 離槽孔後的天雜構(第6目)將會綠㈣通訊品質。Since the dielectric constant of air is low (about 1), the light-emitting efficiency of the antenna structure 200 is greatly improved. Of course, in order to improve the isolation between the antennas, as shown in FIG. 4, a foam 31 or a non-conductive material (for example, a plasticized material) is selectively disposed in the isolation slot 23, so that Avoid interference between individual wireless signals between antennas. Please refer to Fig. 5 and Fig. 6 for the transmission loss diagram of the =-line structure without the isolation slot and the penetration loss diagram of the antenna structure provided with the isolation slot. The creation of the antenna structure for the four frequency points at 2.4 GHz), 2. (2.5 GHz) > 3 (λ ο-η Λ 4.9 〇Ηζ) and 4. (5.8 GHz) for the S-parameter measurement is as shown in the fifth The figure shows four frequency points with curves and -22db. The antenna structure is not provided with an isolation slot, and the S parameter measured at the frequency is about -8 db, -9 db, -19 db, and the antenna structure is not provided with the isolation slot as in the sixth & - ^ ... The S-parameters measured at the four frequency points of the frequency-curvature curve are approximately the losses b, -16 db, - 12 M349564 21 db and -33 db. It can be seen from the S parameter of the above measurement 1 that the antenna structure of the isolation slot (Fig. 6) has higher values of the s parameter measured at each frequency point than the antenna structure without the isolation slot (Fig. 5). ) It is still low, which means that the hybrid structure (item 6) after the isolation slot is added will be green (four) communication quality.
