Abstract

The invention discloses a single feed line inner multiple frequency antennas; it adopts single feed line structure to receive and send multiple frequency signal. The antennas in the invention adopts the structure of plane piece and metal stripline to form the first, the second low frequency radiation frequency; high frequency resonance component is mounted in the Inner space of plane piece and metal stripline, by optimizing the structure and position, at the same time with forming the third radiation frequency, the first, the second resonance frequency are close with each other, so the bandwidth of antennas is extended efficiently. Because the effective usage of structure inner space is used to adjust and form the receiving and sending multiple frequency signals, the antennas can decrease the mobile telephone inner space; at each frequency point, the impedance speciality keeps identical, the feed circuit is simple, matching performance is well, cost is low.

Description

technical field

[0001] The invention relates to a single-feeder built-in multi-band antenna for mobile communication terminals. In particular, it relates to a single-feed built-in antenna device for a mobile phone capable of receiving and transmitting multi-band signals. Background technique

[0002] Mobile phones initially only worked on a single frequency. Since Europe and Asia usually use one of the two frequencies 900MHz or 1800MHz specified by the European GSM Committee, there are mobile phone antennas that support both frequencies. With the rapid development of mobile communication technologies, the functions of mobile terminals are increasingly diversified. In addition to traditional voice communication through the mobile phone network, the mobile terminal also has functions such as Internet browsing, mobile multimedia reception, wireless navigation and positioning, and mobile digital TV. The technologies they use include Bluetooth, IEEE802.11b (Wireless Local Area...
