M310387 八、新型說明： 【新型所屬之技術領域】 本新型是有關於一種無線行動通訊之裝置，且特別是 有關於一種無線網路卡之裝置。 【先前技術】 隨著行動通訊需求的日益增加，無線通訊的技術與設 備也不斷地被開發出來。這些無線通訊的技術與設備除了 追求通訊速度與品質上的提昇之外，在設備的使用便利性 方面、外觀要求方面、攜帶要求方面等也必須符合消費者 的需求。 一般來說，可攜式的電子資訊產品，如筆記型電腦必 須透過無線網路卡才能建立無線通訊的環境。無線網路卡 因應不同的無線通訊技術會有不同的設計與要求。這些無 線通訊技術中，尤其以行動通訊（mobile communication)技 術的發展與使用，最為快速與便利。 近期以來，行動通訊技術主要著重於傳輸速度上的提 昇，較為主要的通訊協定，如第2代的全球行動通訊系統 (Global System for Mobile Communications，GSM)、第 2·5 代的整合封包無線電服務（General Packet Radio Service， GPRS)、第3代的寬頻分碼多工存取（Wideband CDMA， WCDMA)、到第3.5代的高速下行封包存取（High Speed Downlink Packet Access，HSDPA)等，經由一代代技術的 改善，使得行動通訊通訊的資料傳輸速度大幅的提昇。 6 M310387 一般來說，無線網路卡上設有天線以接收與傳送無線 訊號。天線的位置與設計，往往會是影響訊號接收與傳送 效能的最主要因素之一，直接會影響資料傳輸的速度與品 質。又由於各個國家所採用行動通訊技術的使用頻率不盡 相同，可攜式的電子資訊產品的使用環境也會隨著使用者 的移動而改變，單一天線並無法滿足達到良好訊號接收與 傳送效率的要求。 因此，為了改善在行動通訊（如使用第3代或第3.5代 技術）時，語音或資料傳輸的通訊聯結（link)品質，行動接收 分集（Mobile receive diversity)的方法已經被認為是一種快 速且便宜的方法。所謂天線分集的方法，即是利用不同天 線經由不同的路徑條件以不同路徑輸出，而這些輸出訊號 間會有部分的相關性（partially correlated)。 在接收分集系統中，較為普遍使用的技術即為陣列天 線相互搞合（mutual coupling)技術。對於行動通訊設備的硬 體製造商而言，行動接收分集系統的設計中，可接受的相 互搞合，主要的挑戰來自於高輻射效率（high radiation efficiency)與低衰落相關係數（low fading correlation coefficient) ° 在現有的行動接收分集系統的設計中，已經普遍被使 用的直接方法，即是空間分集（spatial diversity)技術。空間 分集是於不同接收天線間，間隔有半個或多個波長的間 距。然而，這樣會需要較大的空間以容置部份的接收天線， 造成行動通訊裝置整體體積過大。 7 M3103 87 近來，另一種分集方法，稱之為極化分集㈣arizati〇n —_)，也已經被發現具有接近於空間分㈣效率。在 極化刀集了 ’天線間具有互補或是方向性的輻射場型 (radiation pattern) 〇 ^ ^ ^ ^ ^ ^ ^ , ^ 分集可以提供足夠的天線效率。 、因此，可攜式電子資訊產品在使用行動通訊（如使用第 ^代或第3.5代技術）時，需要一種能有效運用極化分集與 場型分集的無線網路卡。 【新型内容】 本新型的目的在提供一種無線網路卡，運用極化分集 與場型分集來達到天線的接收效率。 〃 本新i的另目的在提供一種無線網路卡，以提供輕 巧與美觀的整體外型，符合行動通訊設備便於攜帶的需求。 依據本創作的一種無線網路卡，包含一本體、一電路裝 f、一傳輸介面裝置以及一可調式天線裝置。該本體具有< —插接部以及一外座體，該插接部具有一第一端以及一第 二蠕，該外座體係設於該第二端，並具有一連結座以及兩 •對的側邊中，該連結座係鄰靠於其中—側邊，該第 〜端係界於兩侧邊之間。該電路裝置係設於該本體内。該 輪"面裝置係设於該第一端，並電氣地連接於該電路裝 置。 該可調式天線裝置係可調整地設於外座體的該連結座 上，以供調整該可調式天線裝置對應天線行動接收分集 M310387 (Mobile receive diversity)的最佳效能。該可調式天線裝置 包含一天線本體以及一連結樞軸，該連結樞軸係連結於該 天線本體，並樞設穿置於該連結座。 在一較佳的實施例中，該電路裝置包含至少一個内建天 線，各該内建天線係位於對應該外座體内。各該内建天線 係為一多路徑（multi-path)天線。 藉此’本創作所達成的功效在於： 當樞轉天線本體至相對於本體約為9〇度位置時，可有 效的產生兩正交的極化輻射場型，並減少天線相關性的輕 射場型。可獲得低相⑲合（低於·聽），低衰落相關係數 (小於5)，以及良好的天線輻射效率（大於5〇%)。除此之外， 也增加在設計時，選用天線類型的設計彈性，如可採用倒F 型天線（Planar Inverted F Amenna，piFA)、單輛極 (m〇n〇P〇le)、迴路（l〇〇P)、槽孔（slot)等天線。 同時，也可確保了行動通訊中（如第3代或第3·5代 C D Μ Α行動通訊技術），與使用者間語音或資料傳輸的通訊 聯結（link)品質。 卜天線本體可以相對於本體調整收合，使得無線 網路卡整體具有輕巧與美觀的整體外型。而連結座的位置 ㈣靠於外座體側邊’使得天線本體在達到前述輕巧與美 觀的整體外型的要求下，可以具有最大的長度（即約等於無 線網路卡的寬度）。 【實施方式】 M3103 87 • _參照第1圖與第2圖所示。第1圖係為依照本新型 一較佳實施例的一種無線網路卡的立體圖。第2圖係為第1 圖中無線網路卡的立體分解圖。 ‘ 依據本新型之一無線網路卡100，其包含有一本體 • 110、一可調式天線裝置120以及一傳輸介面裝置13〇。本 體U0具有一插接部111以及一外座體112。本體110内並 設有一電路裝置140。 φ 插接部U1具有一第一端1Π以及一第二端II4,其中 第一端113係相對於第二端114。傳輸介面裝置13〇係設於 A第 ^ 113位置’並電氣地連接於電路裝置140。當使用 無線網路卡1〇0時，係將插接部ill插入一可攜式電子裝 置（如筆記型電腦）的插槽中，使傳輸介面裝置13〇與插槽中 的傳輸介面呈電氣上的連結。傳輸介面裝置13〇可使用 express card傳輸介面、USB傳輸介面、pcMCIa傳輸介面、 CF card傳輸介面等。 外座體U2係設於插接部111的第二端114並包容有部 、 分電路裝置140。外座體112具有一連結座115以及兩相對 的側邊1121，其中，該連結座115的位置係鄰靠於其中一 側邊1121或是設於其中一側邊1121上。連結座115具有 座孔116。該第二端1丨4係界於兩側邊丨丨2丨之間。 可調式天線裝置120係可調整地設於外座體112上， 並電氣地連結於該電路裝置14〇。可調式天線裝置12〇可為 一多頻帶（multi-band)天線，以供調整該可調式天線裝置對 應天線行動接收分集（Mobile receive diversity)的最佳效 M310387 旎。可調式天線裝置12〇包含一天線本體121以及一連結 極轴122。該連結樞軸122係連結於該天線本體121，並樞 沒穿置於該座孔116中。該連結樞軸122係可為一中空金 屬嘗。藉此’可調式天線裝置120的調整方式，可以使用 天線本體121相對於外座體U2樞轉方式調整。 可調式天線裝置12〇更包含一導線123，該導線123穿 設於該連結樞軸122中，其一端並延伸出該連結樞軸122 並電氣地連接於該電路裝置14〇。 此外’電路裝置140於外座體112内，可設有一或一個 以上的内建天線141，内建天線係可為一多路徑（multi-path) 天線。配合可調式天線裝置120，可使無線網路卡 100可適 用於多頻的使用需求。 叫參照第3圖與第4圖所示，第3圖係為第1圖中無 線網路卡的使用狀態立體圖。第4圖係為第3圖中無線網 路卡的側視圖。 备樞轉天線本體121至相對於本體11 〇約為9〇度位置 時，該天線本體121將具有垂直極化輻射場型 (vertiCal-p〇larized radiation pattern)600，而内建天線 141 具有水平極化輪射（h〇rizontal-p〇larized radiates)700。藉由 該天線本體121與内建天線141約為正相交的天線配置， 可以有效達到在行動接收分集中，低衰落（封包）相關係數 (correlation coefficient)小於5的需求。同時也可確保行動 通訊中（如第3代或第3·5代CDMA行動通訊技術），與使 用者間語音或資料傳輸的通訊聯結（Hnk)品質。 π M310387 雖然本新型已以一較佳實施例揭露如上 以限定本新型’任何熟習此技藝者，在不脫離本新=二 神㈣圍内’當可作各種之更動與潤飾，因此本新型之^ s 蒦辄圍當視後附之中請專利範圍所界定者為準。 【圖式簡單說明】M310387 VIII. New Description: [New Technology Field] The present invention relates to a wireless mobile communication device, and more particularly to a wireless network card device. [Prior Art] With the increasing demand for mobile communication, technologies and devices for wireless communication have been continuously developed. In addition to the improvement of communication speed and quality, these wireless communication technologies and devices must meet the needs of consumers in terms of ease of use, appearance requirements, and carrying requirements. In general, portable electronic information products, such as notebook computers, must establish a wireless communication environment through a wireless network card. Wireless network cards There are different designs and requirements for different wireless communication technologies. Among these wireless communication technologies, especially the development and use of mobile communication technology is the fastest and most convenient. Recently, mobile communication technology has mainly focused on the improvement of transmission speed. The main communication protocols, such as the 2nd generation Global System for Mobile Communications (GSM) and the 2nd and 5th generation integrated packet radio services. (General Packet Radio Service, GPRS), 3rd generation of wideband code division multiplex access (Wideband CDMA, WCDMA), to the 3.5th generation of High Speed Downlink Packet Access (HSDPA), etc. The improvement of generation technology has greatly increased the data transmission speed of mobile communication. 6 M310387 In general, an antenna is provided on the wireless network card to receive and transmit wireless signals. The location and design of the antenna is often one of the most important factors affecting the performance of signal reception and transmission, which directly affects the speed and quality of data transmission. Since the frequency of use of mobile communication technologies in different countries is different, the environment in which portable electronic information products are used will also change with the movement of users. A single antenna cannot meet the efficiency of receiving and transmitting good signals. Claim. Therefore, in order to improve the communication quality of voice or data transmission in mobile communication (such as the use of 3rd generation or 3.5th generation technology), the method of mobile receive diversity has been considered as a fast and Cheap way. The so-called antenna diversity method uses different antennas to output different paths via different path conditions, and these output signals are partially correlated. In the receive diversity system, the more commonly used technology is the mutual coupling technology of the array antennas. For hardware manufacturers of mobile communication devices, the design of the mobile receive diversity system is acceptable for each other. The main challenge comes from high radiation efficiency and low fading correlation coefficient. ° In the design of existing mobile receive diversity systems, the direct method that has been commonly used is the spatial diversity technique. Spatial diversity is the spacing between different receiving antennas with half or more wavelengths. However, this would require a larger space to accommodate a portion of the receiving antenna, resulting in an overall bulk of the mobile communication device. 7 M3103 87 Recently, another diversity method, called polarization diversity (IV) arizati〇n —_), has also been found to have near-space (IV) efficiency. In the polarization knives, the radiation pattern 〇 ^ ^ ^ ^ ^ ^ ^ ^ with complementary or directionality between the antennas can provide sufficient antenna efficiency. Therefore, portable electronic information products require a wireless network card that can effectively use polarization diversity and field diversity when using mobile communication (such as using the second generation or the 3.5th generation technology). [New content] The purpose of the novel is to provide a wireless network card that uses polarization diversity and field diversity to achieve antenna reception efficiency.另 The purpose of this new i is to provide a wireless network card to provide a compact and aesthetically pleasing overall appearance that meets the mobility requirements of mobile communication devices. A wireless network card according to the present invention comprises a body, a circuit package, a transmission interface device and a tunable antenna device. The body has a <-plug portion and an outer seat, the plug portion has a first end and a second creep, the outer seat system is disposed at the second end, and has a joint and two pairs In the side of the side, the connecting seat is adjacent to the side, and the first end is bounded between the two sides. The circuit device is disposed in the body. The wheel & face device is disposed at the first end and is electrically connected to the circuit device. The adjustable antenna device is adjustably disposed on the connecting base of the outer base body for adjusting the optimal performance of the adjustable antenna device corresponding to the antenna receive diversity M310387 (Mobile receive diversity). The adjustable antenna device includes an antenna body and a connecting pivot, and the connecting pivot is coupled to the antenna body and pivotally disposed on the connecting base. In a preferred embodiment, the circuit arrangement includes at least one built-in antenna, each of the built-in antennas being located in a corresponding outer housing. Each of the built-in antennas is a multi-path antenna. The effect achieved by this creation is: when pivoting the antenna body to a position about 9 degrees relative to the body, it can effectively generate two orthogonal polarization radiation patterns and reduce the antenna correlation light field type. Low phase 19 (below), low fading correlation coefficient (less than 5), and good antenna radiation efficiency (greater than 5〇%) are available. In addition, the design flexibility of the antenna type is also selected in the design, such as Planar Inverted F Amenna (piFA), single pole (m〇n〇P〇le), loop (l 〇〇P), slot and other antennas. At the same time, it can also ensure the communication quality of communication or data transmission between users (such as 3rd generation or 3rd generation C D Μ Α mobile communication technology). The antenna body can be adjusted and folded relative to the body, so that the wireless network card as a whole has a light and beautiful overall appearance. The position of the joint (4) depends on the side of the outer seat so that the antenna body can have the largest length (i.e., approximately equal to the width of the wireless network card) under the requirements of the aforementioned lightweight and aesthetic overall appearance.

When the wireless network card is used, the plug portion ill is inserted into the slot of a portable electronic device (such as a notebook computer), so that the transmission interface device 13 is electrically connected to the transmission interface in the slot. The link on. The transmission interface device 13 can use an express card transmission interface, a USB transmission interface, a pcMCIa transmission interface, a CF card transmission interface, and the like. The outer housing U2 is disposed at the second end 114 of the plug portion 111 and houses the portion and sub-circuit device 140. The outer housing 112 has a connecting seat 115 and two opposite side edges 1121. The connecting seat 115 is located adjacent to one of the side edges 1121 or on one of the side edges 1121. The joint 115 has a seat hole 116. The second end 1丨4 is bounded between the two sides 丨丨2丨. The adjustable antenna device 120 is adjustably disposed on the outer housing 112 and electrically coupled to the circuit device 14A.

The adjustable antenna device 12A includes an antenna body 121 and a connecting pole shaft 122. The connecting pivot 122 is coupled to the antenna body 121 and is pivotally inserted into the seat hole 116. The attachment pivot 122 can be a hollow metal taste.

In conjunction with the adjustable antenna device 120, the wireless network card 100 can be adapted to the needs of multiple frequencies. Referring to Figs. 3 and 4, Fig. 3 is a perspective view showing the state of use of the wireless network card in Fig. 1. Figure 4 is a side view of the wireless network card in Figure 3.
