    Abstract: 近年來通訊產業的迅速發展,對於天線產品的研究與小型的無線模組需求的增加,無線通訊產品在生活中是不可缺少的,為達到無線的需求,無線通訊頻帶要求多頻帶和寬頻,而PIFA具有尺寸小、重量輕、低姿式的特性,在無線通訊的應用上扮演著重要的角色。本論文提出多頻與寬頻的天線設計以節省材料與降低成本考量,在多頻天線方面是以F 型天線為基礎,但F 型天線頻段是雙頻,故本論文基於現有的架構加以改良並加上適當的分支微帶線的設計,運用此方法能產生具有多頻帶的天線,頻帶分別為9OOMHZ /1800MHZ 及 85OMHZ/9OOMHZ/1800MHZ/1900MHZ。 The rapid development of the communication industry in recent years,The wireless communication products ,As to antenna products research and small module for wireless require,The application communications require multi-band and wideband operation. PIFA antennas have the advantage of light weight small size and low profile and had found wide application in wireless communication. We suggest multi-band and wideband antennas to economize resource and reduce cost.The multi-band antenna is base on F antenna and we microstrip lines to reform the F antenna. Therefore the frequencies of the proposed multi-band ,we design antenna are 900MHZ band ~1800MHZ band, 850MHZ/900MHZ band~ 1800MHZ /1900MHZ band。
