The invention discloses a miniaturized mobile phone antenna and a mobile phone covering multiple navigation frequency bands, which include a base plate, a grounding plate, a first L-shaped branch, a C-shaped branch, an S-shaped branch and a second L-shaped branch. The first L-shaped branch is a feeder belt, the C-shaped branch is a parasitic belt, and the S-shaped branch and the second L-shaped branch form a short-circuit belt. The main purpose of the present invention is to provide a solution to integrate the navigation antenna into the main communication antenna to save space. This antenna can not only work in multiple frequency bands of 2G / 3G / 4G, but also cover the four major global navigation systems. While covering so many frequency bands, the antenna structure of the present invention is extremely compact, only occupying a substrate area of 15mm*30mm, which not only realizes multi-frequency and miniaturization, but also has a simple structure and is easy to manufacture, and has high application value .
Description
Technical field [0001] The invention belongs to the field of antenna technology, and specifically relates to a miniaturized mobile phone antenna and a mobile phone that cover multiple navigation frequency bands. Background technique [0002] The rapid development of mobile communication technology has experienced the first generation of analog voice systems and the second generation of narrowband digital voice systems since the 1980s, entering the third and fourth generations of mobile communications (3G, 4G), and gradually moving to the fifth generation. Moving forward in the direction of mobile communications (5G). And each generation of standard has different communication frequency bands. For example, the main GSM systems in my country in the 2G standard are GSM900 and GSM1800, which use the 900MHz and 1800MHz frequency bands respectively. Therefore, various users on the market now have different frequency band requirements, which requires the mobile phone antenna to cover a...
