Description of the Invention: [Technical Field] The present invention relates to an antenna module for an electronic device. An antenna module, in particular, a pair that can select different antennas to receive signals according to different conditions [Prior Art]
T圖】及圖2所示，是習知—種外露式平板天線10, 其^ 11樞接在個人數位助理（以下簡稱PDA)12之上端緣 J因此可以該端U為樞點向上樞轉展開以接收(或發送:訊 唬，或者向下樞轉而收折在PDA丨2的背面。 且在安裝有一全球定位系統（GPS)之PDA 12巾，平板 天線10係用以接收衛星訊號並提供給GPS進行定位。但由 於平板天線10是圓形極化天線，具有指向性的問題，亦即 其只有在PDA為直立放置的情況下，具有較佳之接收效能 ，因此當PDA被向左或向右轉9〇度橫向放置時，平板天線 ίο接收訊號的效能將會因其指向性而降低，而使得Gps的 疋位速度及效能因而受到影響。 因此，為了配合PDA直立或橫向放置的需求，必須使 平板天線1 0可以隨著PDA轉動而轉動，但這除了會增加 PDA機構設計上的困難度與複雜度外，而且無法使用内藏 式天線，而使得PDA必須佔用更多空間。 【發明内容】 因此，本發明之目的，即在提供一種不需大幅變更電 子裝置之機構，即可因應電子裝置之不同擺設方式，產生 1255613 良好接收效能之雙天線模組。 於是，本發明之雙天線模組，係設在一包含一系統模 組之電子裝置上，且該電子裝置具有一第一面及一與該第 面垂直之第二面。該雙天線模組包括一第一天線、—第 二天線與一放大及切換單元。該第一天線設在該第一面。 4第一天線设在該第二面。該放大及切換單元用以放大該 弟一及第二天線所接收訊號，並可受控制地選擇該第一天FIG. 2 and FIG. 2 show a conventional exposed-type panel antenna 10, which is pivotally connected to an upper edge J of a personal digital assistant (hereinafter referred to as PDA) 12 so that the end U can pivot upward. Expand to receive (or send: signal, or pivot down to fold back on the back of the PDA 丨 2. And install a GPS (PDA) PDA 12, the flat antenna 10 is used to receive satellite signals and Provided to the GPS for positioning. However, since the panel antenna 10 is a circularly polarized antenna, it has a problem of directivity, that is, it has better receiving performance only when the PDA is placed upright, so when the PDA is left or When turning right to 9 degrees horizontally, the performance of the flat panel antenna ίο receiving signal will be reduced due to its directivity, which will affect the clamping speed and performance of the Gps. Therefore, in order to meet the needs of PDA upright or horizontal placement The panel antenna 10 must be rotated as the PDA rotates, but this not only increases the difficulty and complexity of the PDA mechanism design, but also eliminates the need for a built-in antenna, so that the PDA must occupy more space. Therefore, the object of the present invention is to provide a dual antenna module with good receiving performance of 1255613 in response to the different arrangement of the electronic device by providing a mechanism that does not require a major change in the electronic device. The antenna module is disposed on an electronic device including a system module, and the electronic device has a first surface and a second surface perpendicular to the first surface. The dual antenna module includes a first antenna a second antenna and an amplification and switching unit. The first antenna is disposed on the first surface. 4 The first antenna is disposed on the second surface. The amplification and switching unit is configured to amplify the first and second The signal received by the two antennas and can be controlled to select the first day
