Description

行動裝置 Mobile device

本發明係關於一種行動裝置，特別係關於包括一耦合式饋入天線結構(Coupled-fed Antenna Structure)之行動裝置。 The present invention relates to a mobile device, and more particularly to a mobile device including a coupled-fed Antenna Structure.

隨著行動通訊技術的發達，行動裝置在近年日益普遍，常見的例如：手提式電腦、行動電話、多媒體播放器以及其他混合功能的攜帶型電子裝置。為了滿足人們的需求，行動裝置通常具有無線通訊的功能。有些涵蓋長距離的無線通訊範圍，例如：行動電話使用2G、3G、LTE(Long Term Evolution)系統及其所使用700MHz、850 MHz、900MHz、1800MHz、1900MHz、2100MHz、2300MHz以及2500MHz的頻帶進行通訊，而有些則涵蓋短距離的無線通訊範圍，例如：Wi-Fi、Bluetooth以及WiMAX(Worldwide Interoperability for Microwave Access)系統使用2.4GHz、3.5GHz、5.2GHz和5.8GHz的頻帶進行通訊。 With the development of mobile communication technologies, mobile devices have become more and more popular in recent years, such as portable computers, mobile phones, multimedia players, and other portable electronic devices with mixed functions. In order to meet people's needs, mobile devices usually have the function of wireless communication. Some cover long-range wireless communication range, for example, mobile phones use 2G, 3G, LTE (Long Term Evolution) systems and the 700MHz, 850MHz, 900MHz, 1800MHz, 1900MHz, 2100MHz, 2300MHz and 2500MHz bands used for communication. Others cover short-range wireless communication ranges. For example, Wi-Fi, Bluetooth, and WiMAX (Worldwide Interoperability for Microwave Access) systems use 2.4 GHz, 3.5 GHz, 5.2 GHz, and 5.8 GHz bands for communication.

近年來，行動裝置常加入金屬外觀件(例如：金屬飾板)來增進外型時尚感。然而，這些金屬外觀件的存在往往對於無線通訊之天線元件造成負面影響，進而降低行動裝置之通訊品質。 In recent years, mobile devices often incorporate metal-like parts (such as metal plaques) to enhance the stylish look. However, the presence of these metal-looking components often has a negative impact on the antenna components of the wireless communication, thereby reducing the communication quality of the mobile device.

The aperture 165 is for receiving a data transmission component (not shown), such as a Universal Serial Bus Connector (USB Connector) or a Mini Universal Serial Bus Connector (Micro-USB Connector). Therefore, the mobile device 100 can exchange data with an external device (for example, a desktop computer or a notebook computer) via the data transmission component. It must be noted that the opening 165 is not an essential structure. In other embodiments, the exterior trim 160 can also be a non-perforated solid metal sheet.

Available design space within 100. Since the exterior trim 160 can be considered as another radiating portion of the coupled feed antenna structure, the exterior trim 160 will not adversely affect its antenna radiation performance. Compared to the prior art, the mobile device 100 of the present invention has at least the multiple advantages of improved appearance, reduced overall size, and good communication quality.
