Abstract

【物品用途】;　　本創作係關於一種多頻天線，組裝於電子產品內部，藉此達成電子產品對電磁訊號的接收與發送。;【創作特點】;　　如附圖所示，本創作多頻天線形成於印刷電路板上，在電路板前表面的下部設有一橫向延伸的呈長條形的接地部，接地部上端緣的左側連接有一先向上延伸再向右延伸形成的第一連接部，在第一連接部下端緣的左側連接有一先下延伸再向右延伸然後再向下延伸再向左延伸最後再向下延伸形成的第一輻射部。在電路板前表面的中部設有一大致呈矩形狀的饋入部，在饋入部左側緣的中部連接有一向左延伸的第二輻射部，在饋入部右側緣的中部連接有一向右延伸的第三輻射部。在饋入部右側緣的上部連接有一向右呈上下來回彎折延伸形成的第二連接部，第二連接部的末端緣連接有一先向下延伸再向左延伸並將第三輻射部的前部圍設於其內的第四輻射部。[Use of the item]; This invention is about a multi-frequency antenna, which is assembled inside an electronic product to achieve the reception and transmission of electromagnetic signals by the electronic product. ; [Features of the invention]; As shown in the attached figure, the multi-frequency antenna of this invention is formed on a printed circuit board, and a horizontally extending long strip grounding portion is provided at the lower part of the front surface of the circuit board, and a first connecting portion extending upward and then to the right is connected to the left side of the upper edge of the grounding portion, and a first radiating portion extending downward, then to the right, then downward, then to the left, and finally downward is connected to the left side of the lower edge of the first connecting portion. A roughly rectangular feeding portion is provided in the middle of the front surface of the circuit board, a second radiating portion extending to the left is connected to the middle of the left edge of the feeding portion, and a third radiating portion extending to the right is connected to the middle of the right edge of the feeding portion. A second connecting portion extending to the right in an up-and-down manner is connected to the upper portion of the right edge of the feeding portion, and a fourth radiating portion extending downward and then to the left and enclosing the front of the third radiating portion is connected to the end edge of the second connecting portion.
