Abstract

The invention provides a broadband monopole cellphone antenna which comprises a metal ground, a dielectric plate arranged above the metal ground and a metal antenna piece attached on the surface of the dielectric plate. The metal antenna piece comprises a first radiation unit, a second radiation unit, a connecting portion connecting the first radiation unit with the second radiation unit, and a feeder line electrically connecting the first radiation unit with the metal ground, the connecting portion extends along a long side of the dielectric plate, the first radiation unit and the second radiation unit are connected with one end of the connecting portion respectively and face the other end of the connecting portion to be arranged on the upper surface of the dielectric plate in a manner of serving as multiple folding units, and unfolding length of the first radiation unit is smaller than that of the second radiation unit. The broadband monopole cellphone antenna adopts a folding monopole antenna form, so that occupied area of the antenna is greatly reduced; wide bandwidth is provided, and all frequency bands used in current cellphone communication can be covered.

Description

technical field [0001] The invention relates to the field of mobile phone antennas, in particular to a broadband monopole mobile phone antenna. Background technique [0002] In recent years, with the continuous development of mobile communication technology, my country's mobile communication industry has maintained a high-speed development in the field of wireless applications. As of May 2012, the January-April telecommunication business operation statistics released by the Ministry of Industry and Information Technology show that the cumulative number of mobile phone users in the country has exceeded 1 billion. As the most important device in a mobile phone, the mobile phone antenna's performance is crucial to the communication quality of the mobile phone. Currently, the main communication systems used are 2G, 3G and 4G. GSM is the most widely used second-generation mobile communication system (2G). In order to adapt to different situations of radio frequency allocation i...
