Abstract

The invention provides a double antenna which is provided with a printed circuit board having a first surface and a second surface, a radial wire arranged on the first surface of the printed circuit board and an earth wire which substantially takes the shape of the Chinese character'SHAN' that means mountain in English and is arranged on the second surface of the printed circuit board. The radial wire comprises a plurality of branch wires which are sequentially connected; the branch wires comprise linear structures and continuously bent and circuitous structures, and the linear structures and the circuitous structures are alternately arranged.

Description

【Technical field】 [0001] The invention relates to a composite antenna, especially a high-gain antenna applicable to a wireless local area network. 【Background technique】 [0002] With the rapid development of the wireless communication industry, the application of the wireless local area network is becoming more and more extensive. Therefore, the design of the antenna with high gain is also gradually paid attention to. At the same time, in order to reduce the manufacturing cost and increase the performance, the improvement of its manufacturing method and structure must also be considered. Patent No. TW I241743 of Taiwan Province of China discloses an omnidirectional planar monopole antenna, which increases the gain of the antenna by increasing the radiation metal line segment, but due to the influence of the return circuit, the performance of the antenna is not ideal. [0003] In the present invention, a planar compound antenna design with high gain is proposed. The antenna...
