Antenna structure and communication terminal

Abstract

The invention provides an antenna structure and a communication terminal. The antenna structure comprises a first antenna radiator, a second antenna radiator, a matching network, a frequency selectionnetwork and a signal source; the first antenna radiator and the second antenna radiator are coupled through a gap, the end, far away from the gap, of the first antenna radiator is grounded, a feed point is arranged on the first antenna radiator, and the end, far away from the gap, of the second antenna radiator is grounded; the first end of the matching network is connected with the feed point, and the second end of the matching network is connected with the first end of a signal source; the first end of a frequency selection network is connected with the first position of the second antennaradiator, and the second end of the frequency selection network is grounded; the second end of the signal source is grounded. The antenna structure is used for simultaneously generating a first resonance, a second resonance, a third resonance and a fourth resonance. One gap can excite to generate four resonances, more antenna frequency bands can be achieved by one broken gap, the number of brokengaps can be reduced, and meanwhile, the appearance simplicity and the structural strength of the whole machine are improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an antenna structure and a communication terminal. Background technique [0002] With the rapid development of terminal technology, communication terminals have become an indispensable tool in people's lives, and have brought great convenience to all aspects of users' lives. There are generally multiple antennas on communication terminals, especially in the future 5G terminal antenna frequency bands and the number will increase. However, in the prior art, to achieve more antennas or cover more frequency bands, more gaps and complex circuit structures need to be installed on the communication terminal to achieve more antenna coverage, resulting in an unsophisticated appearance of the communication terminal . Contents of the invention [0003] The embodiment of the present invention provides an antenna structure and a communication terminal to solve the increasing antenna...
