Description
本發明是關於一種平板天線,尤指一種適用於多輻射體以一體成型製造且具有訊號阻絕結構之平板天線。The present invention relates to a panel antenna, and more particularly to a panel antenna suitable for multi-radiator fabrication in one piece and having a signal blocking structure.
由於無線區域網路(Wireless Local Area Networks,WLANs)技術發展愈趨成熟,除了使行動裝置,例如筆記型電腦連上網路更方便外,使得與電腦相關的周邊設備例如印表機、投影機、掃描器、麥克風系統等等也逐漸朝向無線化發展。As wireless local area networks (WLANs) technology matures, in addition to making mobile devices, such as notebook computers, more convenient to connect to computers, peripheral devices such as printers, projectors, Scanners, microphone systems, and the like are also gradually moving toward wireless.
近年來無線通訊技術和半導體製程的快速發展,使得無線通訊已成為生活之必需。無線通訊系統由發射/接收機及天線所組成,其中天線是負責電路與空氣中電磁能量之轉換,為通訊系統中重要之零組件之一。由於電子產品的縮小化及多頻寬之需求,使得天線設計朝向縮小化、結構簡單化及多頻或寬頻的技術方向發展。In recent years, the rapid development of wireless communication technology and semiconductor manufacturing has made wireless communication a necessity for life. The wireless communication system consists of a transmitter/receiver and an antenna, wherein the antenna is responsible for the conversion of electromagnetic energy between the circuit and the air, and is one of the important components in the communication system. Due to the shrinking of electronic products and the need for multiple bandwidths, the antenna design has been developed in a direction of downsizing, simplification of structure, and multi-frequency or wide-band technology.
請參閱圖一,係為習用典型無線網路裝置的天線佈置上視圖。該無線網路裝置內一般係具有包括:一基板5以及兩個平板式或是印刷式的天線61、62。為了提高無線網路裝置的傳輸效能,習用典型無線網路裝置常常配置有兩個或更多個天線61、62。由於在高頻訊號下,該二平板天線61、62若距離過近時很容易有訊號干擾之問題;因此,習知技術必須把二平板天線61、62的位置相離越遠越好,例如但不侷限於分別設置在該基板5之二對角上,以空間距離方式來降低訊號干擾。但由於現今電子裝置的發展趨勢皆朝短小輕薄之目標邁進,體積皆越來越小,單以空間距離方式已無法達到良好之隔離訊號干擾效果。並且,若是使用兩組獨立生產與裝配之平板式天線61、62,不僅製程上及組裝上皆需要更高成本及時間,此對於一般市場對於天線設計的要求,顯然還有進一步改良之空間者。Please refer to FIG. 1 for a top view of the antenna arrangement of a conventional wireless network device. The wireless network device generally includes a substrate 5 and two flat or printed antennas 61, 62. In order to improve the transmission performance of wireless network devices, conventional wireless network devices are conventionally configured with two or more antennas 61, 62. Since the two panel antennas 61 and 62 are easily interfered by the signal when the distance is too high, the conventional technique must separate the positions of the two panel antennas 61 and 62 as far as possible, for example, However, it is not limited to being disposed on two diagonals of the substrate 5, and the signal interference is reduced by a spatial distance. However, as the development trend of today's electronic devices is moving toward the goal of short, light and thin, the volume is getting smaller and smaller, and the spatial isolation method can not achieve good isolation signal interference effect. Moreover, if two sets of panel antennas 61 and 62 independently produced and assembled are used, not only the process and the assembly require higher cost and time, which obviously has room for further improvement of the antenna design requirements in the general market. .

請參閱圖六所示,係為本發明具訊號阻絕結構之平板天線於應用頻帶範圍(2400MHz至2500MHz)內之測試折返損失圖。圖六中之線81、線82、線83分別為第一輻射體、第二輻射體及阻隔部測試折返損失所得之圖形。由圖六可知,本發明具訊號阻絕結構之平板天線1之該第一輻射體11在2400MHz至2500MHz之天線共振頻率下的折返損失大體上是介於-13.029dB至-16.566dB之間;另外,該第二輻射體12在2400MHz至2500MHz之天線共振頻率下的折返損失大體上是介於-13.865dB至-23.590dB之間;且該阻隔部13在2400MHz至2500MHz之天線共振頻率下的折返損失大體上是介於-18.642dB至-29.676dB之間。Please refer to FIG. 6 , which is a test return loss diagram of the panel antenna with the signal blocking structure in the application frequency band range (2400 MHz to 2500 MHz). Line 81, line 82, and line 83 in FIG. 6 are graphs obtained by testing the foldback loss of the first radiator, the second radiator, and the barrier portion, respectively. It can be seen from FIG. 6 that the foldback loss of the first radiator 11 of the panel antenna 1 having the signal blocking structure at the antenna resonance frequency of 2400 MHz to 2500 MHz is substantially between -13.029 dB and -16.566 dB; The foldback loss of the second radiator 12 at an antenna resonance frequency of 2400 MHz to 2500 MHz is substantially between -13.865 dB and -23.590 dB; and the blocking portion 13 is folded back at an antenna resonance frequency of 2400 MHz to 2500 MHz.

It is conceivable that the planar antenna 1 with the signal blocking structure of the present invention increases the blocking portion 13 so that the signals transmitted between the first radiator 11 and the second radiator 12 do not interfere with each other, thereby improving transmission efficiency. It also simplifies the process and reduces the size of the module.
