Description

1327389 -九、發明說明: :【發明所屬之技術領域】 * 本發明涉及一種天線,尤其涉及一種平面天線。 【先前技術】 近年來,由於移動通訊産品之市場需求大增,使得無線通 訊之發展更為迅速’在眾多無線通訊標準中,最引人注目的為 美國電子電機工私師協會(Institute of Electrical and • Electronics Engineers,IEEE)制定的 802.11 無線區域網路 (Wireless Local Area Network,WLAN )協定。該協定制定於 1997年,其不僅提供了無線通訊上許多前所未有之功能,而且 提供了可令各種不同品牌之無線通訊產品得以相通之解決方 案。在IEEE所制定的諸多標準中IEEE 802.11b/g為當前較常 用之標準,其工作頻段為2.4GHz。 天線為移動通訊產品中之一必備高頻組件,其主要功能係 _用來接收及發射電磁波訊號。由於無線通訊產品均朝向輕、 薄、短、小之方向發展,故要求天線所佔面積亦應相應較小。 故如何在兼顧天線之效能的前提下,同時將天線之所佔的面積 減小乃當今天線設計之一大挑戰。 【發明内容】 有鑑於此,有必要提供一種平面天線,使天線所佔據的面 積有效縮小,其可工作於中心頻率為2.4GHz。 一種平面天線,設置於一基板上’用於接收及發射電磁波 61327389 - IX. Description of the invention: : [Technical field to which the invention pertains] * The present invention relates to an antenna, and more particularly to a planar antenna. [Prior Art] In recent years, the market demand for mobile communication products has increased, making wireless communication more rapid. ' Among the many wireless communication standards, the most striking is the Institute of Electrical. And • Electronics Engineers (IEEE) developed the 802.11 Wireless Local Area Network (WLAN) protocol. Established in 1997, the agreement not only provides many of the unprecedented features of wireless communications, but also provides solutions that enable wireless communication products from a variety of brands to communicate. Among the many standards established by the IEEE, IEEE 802.11b/g is the currently more commonly used standard, and its operating frequency band is 2.4 GHz. The antenna is one of the necessary high-frequency components in mobile communication products, and its main function is to receive and transmit electromagnetic wave signals. Since wireless communication products are moving toward light, thin, short, and small, the area occupied by the antenna should be correspondingly small. Therefore, how to reduce the area occupied by the antenna while taking into account the performance of the antenna is one of the major challenges in today's antenna design. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a planar antenna that effectively reduces the area occupied by the antenna, which can operate at a center frequency of 2.4 GHz. A planar antenna disposed on a substrate for receiving and transmitting electromagnetic waves 6
