Description
本發明有關於一種槽孔天線,且特別是一種用於第五代行動通信技術的單槽孔天線。 The present invention relates to a slot antenna, and in particular to a single slot antenna for the fifth generation mobile communication technology.
現有行動裝置如筆記型電腦或智慧型手機的天線都需要多種通信規格與多個頻帶的應用,第五代行動通信則更提供更大的頻寬,更能提升信息響應速度。除了資料傳輸量的提升,也提供了新的衍生應用,實現以往所難以實現的信息功能。 The antennas of existing mobile devices such as notebook computers or smart phones require multiple communication specifications and multiple frequency band applications. The fifth-generation mobile communication provides greater bandwidth and can improve information response speed. In addition to the increase in data transmission volume, it also provides new derivative applications to realize information functions that were difficult to achieve in the past.
現有第五代行動通信主要概分為兩個頻率區段,其一為6GHz以下可稱為Sub-6的應用,提供新應用頻段與新的演算編碼方式。其二,則為毫米波(Millimeter Wave,簡稱mmWave)頻段,提供龐大的資料流量與更高的信息響應能力。在6GHz以下的應用是成本較低廉,現有廠商資源投入門檻度較低的解決方案。然而相比於傳統的無線廣域網路(WWAN,Wireless Wide Area Network),更進一步增加了天線需求的操作頻寬,而使得天線數量或天線尺寸需要更增加,使得在新產品設計方面,對於天線設計產生了新的困難挑戰。 The existing fifth-generation mobile communication is mainly divided into two frequency segments, one of which can be called Sub-6 applications below 6 GHz, providing new application frequency bands and new calculation and coding methods. The second is the millimeter wave (Millimeter Wave, mmWave for short) frequency band, which provides huge data flow and higher information response capability. The application below 6GHz is a solution with lower cost and lower threshold for resource investment of existing manufacturers. However, compared with the traditional WWAN (Wireless Wide Area Network), the operating bandwidth required by the antenna is further increased, and the number of antennas or the size of the antenna needs to be increased, so that in terms of new product design, the antenna design New difficult challenges are generated.
