C corresponds to the case where the distance D is 42.5 mm (mm), 35.5 mm, and 25.5 mm, respectively. As the distance D between the feed unit 7 and the opening 71 of the slotted antenna structure 7 increases, the frequency of the quarter-wave resonance mode M1 of the slotted antenna structure 7 increases. Moreover, it can be seen from FIG. 6 that the distance D between the feed unit 9 and the opening 71 of the slotted antenna structure 7 is also used to adjust the impedance matching of the full-wavelength resonant mode M2 of the closed-cell antenna structure 8. However, the distance D does not affect the frequency of the full-wavelength resonant mode M2 of the closed-cell antenna structure 8. When the distance D between the feed unit 9 and the opening 71 of the slotted antenna structure 7 is increased, the impedance of the full-wavelength resonant mode M2 of the closed-cell antenna structure 8 is closer to 50 ohms, that is, the impedance matching is better. However, in order to adjust the frequency point of the quarter-wavelength resonance mode M1 of the slotted antenna structure 7, the distance D has an appropriate value depending on the frequency selection requirement.
再者,在本發明實施例中,開槽孔天線結構的高階共振模態以及閉槽孔天線結構的高階共振模態可以是對應於2.4GHz的無線網路應用頻段。可替換的,上述高階模態的頻率例如也可以是對應於GSM 1800/1900/UMTS(1710-2170MHz)頻帶, 或是LTE 2300/2500(2300-2690MHz)的頻帶,又例如為5GHz的無線網路應用頻段。然而,上述頻帶僅是用以舉例,本發明並不因此限定開槽孔天線結構的高階共振模態以及閉槽孔天線結構的高階共振模態的應用頻帶。 Furthermore, in the embodiment of the present invention, the high-order resonant mode of the slotted antenna structure and the high-order resonant mode of the closed-cell antenna structure may be a wireless network application frequency band corresponding to 2.4 GHz. Alternatively, the frequency of the above higher-order mode may also be corresponding to the GSM 1800/1900/UMTS (1710-2170 MHz) band, for example. Or the frequency band of LTE 2300/2500 (2300-2690MHz), for example, the frequency band of the wireless network application of 5 GHz. However, the above-mentioned frequency bands are only for exemplification, and the present invention does not thus limit the high-order resonant mode of the slotted antenna structure and the application band of the high-order resonant mode of the closed-cell antenna structure.
綜上所述,本發明實施例所提供的具有天線的電子裝置,適用於具有金屬外殼的電子裝置,不但利用金屬背蓋(第一金屬殼體)實現開槽孔,且將閉槽孔天線結構整合於電子裝置的轉軸。再者,依據本發明實施例所述,本發明實施例所提供的天線設計可以應用於諸如LTE 710MHz、無線廣域網路(WWAN)960MHz、GSM 850(824-960MHz)、GSM 900(880-960MHz)、GSM 1800/1900/UMTS(1710-2170MHz)、LTE 2300/2500(2300-2690MHz)、2.4GHz無線區域網路(WLAN)以及5GHz的WiFi無線區域網路等應用。 In summary, the electronic device with an antenna provided by the embodiment of the present invention is suitable for an electronic device having a metal casing, not only using a metal back cover (first metal casing) to realize a slotted hole, but also a closed slot antenna The structure is integrated into the shaft of the electronic device. Furthermore, according to the embodiment of the present invention, the antenna design provided by the embodiment of the present invention can be applied to, for example, LTE 710 MHz, wireless wide area network (WWAN) 960 MHz, GSM 850 (824-960 MHz), GSM 900 (880-960 MHz). Applications such as GSM 1800/1900/UMTS (1710-2170MHz), LTE 2300/2500 (2300-2690MHz), 2.4GHz wireless local area network (WLAN), and 5GHz WiFi wireless LAN.
