Problems solved by technology
[0004] 1. All frequency bands are matched and debugged through a set of feeder circuits. Due to the large span of frequency bands, when debugging a certain frequency band, the impedance characteristics of other frequency bands will be greatly affected, thus affecting the antenna performance of other frequency bands;
[0005] 2. Use a set of feed circuits for full-band matching debugging. In order to take into account the impact on other frequency bands, the matching flexibility is poor;
[0006] 3. The cost of adjustable components is high, and parameter values are difficult to obtain

The present invention provides an antenna for a mobile terminal and a mobile terminal with the antenna. The antenna includes a radiator, a feeder, and a switch, and the switch includes a fixed terminal connected to the radiator and a At least two free ends, switch the fixed end and one of the free ends to be in a connected state; at least two sets of feed circuits, one end of the feed circuit is connected to one of the free ends of the switch, and the other end is connected to the The feeder terminal is connected; the switch selects a feeder circuit to be connected to the radiator, and the radiator generates a feeder signal at the feeder terminal through the feeder circuit after receiving a wireless signal. The technical scheme of the present invention divides the signal of the whole frequency band into multiple combinations or multiple single frequency bands for input, and the matching flexibility of the feed circuit is good; compared with the loss of the adjustable component signal, the performance of a single frequency band can be maximized Excellent, improve natural performance.
Description
technical field [0001] The present invention relates to the field of antennas, in particular to an antenna for a mobile terminal and a mobile terminal with the antenna. Background technique [0002] Today, with the development of communication technology, 2G, 3G, 4G, WIFI, and GPS networks coexist. In order to be compatible with different networks, the antenna of the mobile device needs to be able to work in multiple frequency bands. In the field of mobile terminal equipment, the design environment of the antenna is very complex, the space is limited, and it must be considered to share the space structure with other functional components. One of the limitations is that simply designing any of the above-mentioned antennas cannot cover all the required frequency bands. In order to meet the needs of working in multiple frequency bands, multiple antenna units must be designed and the antennas must be used for full-band coverage. test. The antenna includes a feed circuit, and t...
