The invention discloses a miniaturized mobile phone antenna covering various navigation frequency bands, and a mobile phone. The antenna comprises a substrate, an earth 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 feed band, the C-shaped branch is a parasitic band, and the S-shaped branch and the second L-shaped branch form a short circuit band. An objective of the invention is to provide a scheme. A navigation antenna is integrated in a communication main antenna to save space. The antenna can operate in 2G / 3G / 4G and multiple frequency bands, and covers four global navigation systems. While covering so many frequency bands, the antenna structure is very compact. The antenna just takes 15 mm* 30 mm of area of the substrate, so multi-frequency-band and miniaturization are realized. The antenna is simple in structure and easy in manufacturing, and has very high application value.
Description
technical field [0001] The invention belongs to the technical field of antennas, and in particular relates to a miniaturized mobile phone antenna and a mobile phone covering multiple navigation frequency bands. Background technique [0002] Mobile communication technology has developed rapidly. Since the 1980s, it has experienced the first-generation analog voice system, the second-generation narrowband digital voice system, entered the third and fourth-generation mobile communications (3G, 4G), and gradually moved to the fifth-generation Moving forward in the direction of mobile communication (5G). And each generation standard has different communication frequency bands. For example, in the 2G standard, the main GSM systems in my country are GSM900 and GSM1800, which use 900MHz and 1800MHz frequency bands respectively. Therefore, all kinds of users in the market now have different frequency band requirements, which requires mobile phone antennas to cover as many frequency ...
