Description
本發明係有關於一種天線結構，特別是一種寬頻天線結構。 The present invention relates to an antenna structure, and more particularly to a wideband antenna structure.
近年來，無線通訊技術快速的發展，長期演進(Long Term Evolution，通常簡稱為LTE)行動通訊技術應運而生；由於LTE的LTE700/2300/2500的頻段涵蓋了704~960MHz及1710~2690MHz，涵蓋了無線廣域網路(Wireless Wide Area Network，通常簡稱為WWAN)五頻操作，相較於傳統的無線區域網路(Wireless Local Area Network，通常簡稱為WLAN)2.4G、5G天線，LTE天線涵蓋較低頻及更大的頻寬；因此，如何兼顧天線多頻操作與收訊品質為天線設計時需要留意之處。 In recent years, the rapid development of wireless communication technology, Long Term Evolution (LTE) mobile communication technology came into being; because the LTE LTE700/2300/2500 frequency band covers 704~960MHz and 1710~2690MHz, covering The wireless wide area network (Wireless Wide Area Network, usually referred to as WWAN) has five-frequency operation. Compared with the traditional wireless local area network (Wireless Local Area Network, usually referred to as WLAN) 2.4G, 5G antenna, LTE antenna covers lower. Frequency and larger bandwidth; therefore, how to balance the antenna multi-frequency operation and receiving quality for antenna design needs to pay attention to.
然而，目前習知的各種類型的天線裝置僅具備雙頻收發或三頻的發射接收電磁波訊號的功能，無法滿足現今4G通訊領域的通訊頻帶，且在使用上仍多所限制。 However, various types of antenna devices of the prior art only have the functions of transmitting or receiving electromagnetic wave signals by dual-frequency transmission or transmission, and cannot meet the communication frequency band of the current 4G communication field, and are still limited in use.

It must be connected to a diplexer to separate two different feed signals (such as GSM and DCS) and then connected to the back-end module; the switch circuit will occupy part of the space of the mobile circuit module. Part of the power is also consumed, resulting in reduced overall antenna efficiency and increased matching complexity.
