<p>Disclosed in the present invention are a communication terminal and an antenna system thereof. The communication terminal comprises: a mainboard; and the antenna system connected with the mainboard; the antenna system comprises: a radio frequency signal transmitting and receiving terminal, a frequency dividing device connected with the radio frequency signal transmitting and receiving terminal, and a high-frequency antenna and a low-frequency antenna both connected with the frequency dividing device; the frequency dividing device is used for outputting a radio frequency signal, received by the radio frequency signal transmitting and receiving terminal, to the high-frequency antenna or the low-frequency antenna according to the frequency of the radio frequency signal; the high-frequency antenna is disposed on the middle area of a communication terminal end; the low-frequency antenna is disposed on the communication terminal end and comprises: a first wiring connected with a feeding end, a second wiring connected with a ground end and a third wiring connecting the first wiring with the second wiring, and the first wiring and the second wiring are oppositely disposed on the two sides of the high-frequency antenna. As a result, the radiance performance of the antenna system of the communication terminal can be improved on the basis of good adaptability to a trend of developing lightweight and thinned communication terminals.</p> |
