Description
本創作係有關一種天線,尤指一種低電磁波能量的特定吸收比率(SAR)值的天線結構。 This creation relates to an antenna, and more particularly to an antenna structure having a specific absorption ratio (SAR) value of low electromagnetic energy.
隨著科技不斷的提昇下,許多移動式電子裝置相繼的被發展出來,如現在市售的平板電腦。由於平板電腦的體積輕薄短小,且攜帶方便,因此廣被各種行業及各單位購買使用。 With the continuous improvement of technology, many mobile electronic devices have been developed, such as tablet PCs that are currently on the market. Because the tablet is light and thin, and easy to carry, it is widely used by various industries and units.
在產品要被相關單位採購時,該產品都必須經過嚴格的檢驗,在檢驗的項目中包含落摔、防震、高低溫運作、EMI/EMC干擾…等,在這些檢驗的項目中落摔測試要進行該產品26個點線面的落摔測試。由於產品在進行落摔測試時,產品的殼體的角落處都是最脆弱的部位,因此有很多產品都無法通過摔落法規檢驗,因此為了通過該法規檢驗,業者常於該產品的殼體內部角落增加補強的金屬塊或金屬器件,在該殼體內部角落上增加補強的金屬塊或金屬器件補強後,可增加機器本身的機構強度,達到通過摔落規範。 When the product is to be purchased by the relevant unit, the product must undergo rigorous inspection, including falling, shockproof, high and low temperature operation, EMI/EMC interference, etc. in the inspection items. A 26-point line drop test of the product was carried out. Since the product is in the corner of the product, the corners of the product are the most vulnerable parts. Therefore, many products cannot be tested by the fall regulations. Therefore, in order to pass the inspection, the manufacturer often uses the housing of the product. The corners of the part are added with reinforcing metal blocks or metal parts. After the reinforcing metal blocks or metal parts are reinforced on the inner corners of the casing, the mechanical strength of the machine itself can be increased to meet the specification of falling.
雖然,在產品的殼體內部角落上增加補強的金屬塊或金屬器件可通過摔落法規檢驗,但是該金屬塊或金屬器件會使得天 線SAR值提高,無法通過FCC SAR法規檢測。 Although the addition of reinforcing metal blocks or metal parts to the inner corners of the product's casing can be verified by falling regulations, the metal block or metal device will make the day The line SAR value is increased and cannot be detected by the FCC SAR regulations.
