Description

The operational characteristics of the signal provide the antenna with an approximately omnidirectional radiation pattern. However, the length-to-short axis ratio of the pattern of the planar antenna on the antenna and the non-uniform uniform line width are not easy to adjust in design, and the pattern of the antenna is more complicated and difficult to lay, so that the micro-shaped antenna is designed to exist. Many troubles.

As shown in the figure, in the capacitive antenna structure of the present invention, the antenna 10 has a substrate 1 which is any one of glass fiber or ceramic. The substrate 1 has a front surface 11 having a radiant metal layer 12 therein. The radiant metal layer 12 has a first hollow portion 13 having a circular shape for exposing the front surface 11 of the substrate 1. The first hollow portion 13 is There is a signal feeding hole 14 , the first hollow portion 13 keeps the signal feeding hole 14 and the radiation metal layer 12 at a distance to form a non-electrical connection state, and the signal feeding hole 14 can be connected to a general wire. (not shown). In addition, a square or rectangular second hollow portion 15 is formed on the edge of the radiant metal layer 12.
請參閱第三、四、五圖，係本發明之天線背面外觀立體及第三圖的局部放大與第四圖電性連結片狀形電容器示意圖。如圖所示：該基板1具有一背面16，該背面16上具有一接地金屬層17，該接地金屬層17邊緣上具有一對應該第二鏤空部15的第一接點171及第二接點172，該第一接點171及該第二接點172之間具有使基板1背面16外露的第三鏤空部18，該第三鏤空部18對應該基板1正面11的第二鏤空部15該第三鏤空部18相連有一呈S形的第四鏤空部19，該第四鏤空部19中具有一L形的訊號傳輸線173，該訊號傳輸線173上包含有該訊號饋入孔14，該訊號饋入孔14插接一般導線(圖中未示)時，可與該訊號傳輸線173電性連結。 Please refer to the third, fourth and fifth figures, which are a perspective view of the rear side of the antenna of the present invention, and a partial enlarged view of the third figure and a schematic view of the fourth embodiment of the electrically connected chip capacitor. As shown in the figure, the substrate 1 has a back surface 16 having a grounded metal layer 17 having a pair of first contacts 171 and second contacts on the edge of the ground metal layer 17 which should be the second hollow portions 15. Point 172, between the first contact 171 and the second contact 172, has a third hollow portion 18 exposing the back surface 16 of the substrate 1, and the third hollow portion 18 corresponds to the second hollow portion 15 of the front surface 11 of the substrate 1. The third hollow portion 18 is connected to the S-shaped fourth hollow portion 19, and the fourth hollow portion 19 has an L-shaped signal transmission line 173.

該電容器2，為片狀形可以表面黏著於該第一接點171及第二接點172上，並對應基板1正面的第二鏤空部15。當有電流流入時，該 電流會流經該第一接點171及該電容器2至該第二接點172，使天線結構的能量被耦合及激發出來，而且流經電容器2的電流被激盪出來，讓天線結構的接收或發射訊號的效果更佳。同時，在電容器2所對應基板1正面11的第二鏤空部15，主要是避免電容器2被遮蔽(短路)，而形成天線的高頻短路現象。該第二鏤空部15的面積大於該電容器2的表面積。 The capacitor 2 has a sheet shape and can be surface-bonded to the first contact 171 and the second contact 172 and corresponds to the second hollow portion 15 on the front surface of the substrate 1. When there is current flowing in, Current will flow through the first contact 171 and the capacitor 2 to the second contact 172, so that the energy of the antenna structure is coupled and excited, and the current flowing through the capacitor 2 is excited to allow the antenna structure to be received or The effect of transmitting a signal is better. At the same time, the second hollow portion 15 of the front surface 11 of the substrate 1 corresponding to the capacitor 2 mainly prevents the capacitor 2 from being shielded (short-circuited), thereby forming a high-frequency short-circuit phenomenon of the antenna. The area of the second hollow portion 15 is larger than the surface area of the capacitor 2.
