Description
本創作係關於立體式天線，尤指一種應用於嵌入式無線基地台中，且二天線會直立於電路板上，並在其間設有中性線，以能形成高隔離度的天線架構。 This creation is about a stereo antenna, especially one that is used in an embedded wireless base station, and the two antennas stand upright on the circuit board with a neutral line in between to form a high isolation antenna structure.
近年來，隨著無線通訊產業的迅速發展，各種無線通訊設備亦不斷地推陳出新，市場上對該等無線通訊設備之要求，除了著重其外觀上的輕薄短小，更著重其是否能兼顧穩定傳輸訊號的通訊品質，其中，「天線」更是該等無線通訊設備中，用以收發無線訊號並傳輸數據所不可或缺的關鍵元件，其相關技術的研發亦隨著無線通訊產業的迅速發展，成為相關技術領域所關注的焦點。 In recent years, with the rapid development of the wireless communication industry, various wireless communication devices are constantly being introduced. The requirements for such wireless communication devices in the market, in addition to focusing on the thinness and shortness of its appearance, focus on whether it can balance the stable transmission signals. The communication quality, among them, "antenna" is the key component of these wireless communication devices, which is indispensable for transmitting and receiving wireless signals and transmitting data. The development of related technologies has also become a rapid development of the wireless communication industry. The focus of the related art.
承上，「天線」係一種能將電磁能量(electromagnetic energy)發射至空間中或從空間中接收電磁能量的導電體或導電系統，一般言，天線會同時朝四面八方輻射出電磁能量，令該電磁能量所形成之無線訊號能被遠端的其他電子設備所接收，而根據不同的天線結構，無線訊號在不同方向的傳輸效能也有所差異，此一特性的圖形化顯示方式即為「輻射場型(Radiation Pattern)」，且依照產品需求及輻射場型的不同，天線大致可區分為全向式(Omni-directional)天線及指向性(Directional)天線。傳統上，常見的 一種天線製作技術乃將天線設置於該等無線通訊設備內部之電路板上，尤有甚者，為了避免該等無線通訊設備內部電子零件在運作時產生的電磁波對天線造成干擾，該等無線通訊設備之天線多被設置於該等無線通訊設備的內部角落並加以包覆隔離。前述之設計方式，不僅大大地限制了通訊品質效能之提昇，且為了在該等無線通訊設備內部適當地配置天線，將使得整體產品難以達到輕薄短小的設計目標。 According to the above, "antenna" is an electric conductor or a conductive system capable of emitting electromagnetic energy into or receiving electromagnetic energy from space. Generally speaking, the antenna radiates electromagnetic energy in all directions at the same time, so that the electromagnetic The wireless signal formed by the energy can be received by other electronic devices at the remote end. According to different antenna structures, the transmission performance of the wireless signal in different directions is also different. The graphical display mode of this feature is the "radiation field type". (Radiation Pattern), and depending on the product requirements and the radiation field type, the antenna can be roughly classified into an Omni-directional antenna and a Directional antenna. Traditionally An antenna fabrication technique is to place an antenna on a circuit board inside the wireless communication device, and in particular, in order to avoid electromagnetic waves generated by the internal electronic components of the wireless communication device from interfering with the antenna, the wireless communication The antennas of the device are mostly disposed in the inner corners of the wireless communication devices and are covered and isolated. The foregoing design method not only greatly limits the improvement of communication quality performance, but also makes it difficult to achieve a light, thin and short design goal in order to properly configure the antenna inside the wireless communication devices.
此外，對於小坪數的房型來說，為能節省居住空間，「嵌入式無線基地台」亦成為人們熱愛的產品，然而，由於「嵌入式無線基地台」的使用方式，是嵌入於牆壁中，因此，其天線設計及天線所能形成之場形、隔離度、返回損失比...等特性，均較一般桌上型無線基地台更為嚴苛與困難。 In addition, for the small flat number of rooms, in order to save living space, "embedded wireless base station" has become a favorite product, however, because the "embedded wireless base station" is used in the wall, Therefore, the characteristics of the antenna shape, isolation, return loss ratio, etc. formed by the antenna design and the antenna are more severe and difficult than the general desktop wireless base station.
