Abstract
An antenna element includes a feed probe, an insulating sleeve, and a reflecting cavity. The reflecting cavity is formed by an inner concave of an outer side of the metal frame of the metal back cover. The reflecting cavity includes a first wall and a second wall. One end of the feed probe is connected with the first wall. The middle of the feed probe is connected with the second wall through an insulating sleeve, and the other end of the feed probe is connected with a signal feeder line. The present invention also provides an RF frontend system which includes the above mentioned antenna system. Through an architecture which includes a feed probe and a reflecting cavity, the present invention realizes that the 5G antenna is arranged at the sides of the mobile terminal. Therefore the 5G antenna can coexist with 3G, 4G, GPS, WIFI and other antennas.
