The invention provides a mobile terminal and a millimeter wave broadband array antenna. The millimeter wave broadband array antenna comprises an antenna body, an antenna ground and a feed line which are located in a first metal layer. The antenna body comprises at least two array elements in the form of metal patches, the outer side of the array elements is provided with a slot and the outer sideof the slot is provided with the antenna ground. The feed line comprises a coplanar waveguide port and at least one stage power divider connected with the coplanar waveguide port. The power divider has a line structure comprising one input end and two output ends, and the feed line comprises an intermediate metal conductor and two side antenna grounds. Each output end of the last power divider iscorrespondingly connected with one array element to form an array coplanar waveguide antenna. The problem of narrow feed band width of the traditional microstrip line can be solved and greater improvement of antenna bandwidth performance can be realized; and the lower directivity level can be guaranteed and the antenna gain can be effectively improved.
Description
technical field [0001] The invention relates to the field of mobile communication, in particular to a mobile terminal and a millimeter-wave broadband array antenna. Background technique [0002] With the rapid development of 5G mobile communication technology, the demand for 5G mobile terminals in the application market continues to increase. The ultra-high data transmission rate of 5G technology will have a significant impact on the user's application experience, and the communication performance of the antenna is important in data transmission. play a vital role in the process. [0003] The 5G frequency band is divided into Sub-6GHz and 28GHz / 39GHz millimeter wave frequency bands: for the Sub-6GHz frequency band, the antenna shape is similar to that of the existing LTE frequency band; but when it comes to the millimeter wave frequency band, due to transmission path loss and space loss A series of problems, antenna shape and layout are also undergoing major changes; accord...
