Embodiment Construction

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0043] The invention discloses a diversity antenna system. Compared with the existing diversity antenna system, the cost is lower.

[0044] see figure 2 , figure 2It is a structural schematic diagram of a diversity antenna system disclosed in the present invention. The diversity antenna system includes a main antenna 101 , a diversity antenna 102 , a first duplexer 103 , a second duplexer 104 , a third duplexer 105 and a switching component 106 .

Abstract

Embodiments of the invention disclose a diversity antenna system. A quadruplexer in an existing diversity antenna system is replaced by a first duplexer, a second duplexer and a switching assembly, a main antenna, a diversity antenna and an original third antenna in an electronic device are used for achieving diversity sending and receiving of data, and since the costs of the duplexers and a switch are much lower than the cost of the quadruplexer, the diversity antenna system disclosed by the invention has the advantages of low cost. In addition, the first duplexer and the second duplexer are spatially isolated, thereby having better isolation than the quadruplexer, and thus the out-of-band rejection performance of the diversity antenna system can be improved. The invention further discloses an electronic device with the diversity antenna system and a control method applied to the electronic device.

Description

technical field [0001] The invention belongs to the technical field of antennas for electronic equipment, and in particular relates to a diversity antenna system, an electronic equipment and a control method thereof. Background technique [0002] Diversity technology is an anti-fading technology. A diversity antenna system is an antenna system that utilizes diversity technology. [0003] figure 1 The structure of an existing diversity antenna system is shown, including a main antenna 01 , a diversity antenna 02 , a quadruplexer 03 and a duplexer 04 . Transceiver 05 has two transmit ports, two main receive ports and two diversity receive ports. The two transmitting ports and the two main receiving ports of the transceiver 05 are respectively connected with the quadplexer 03, and the quadplexer 03 is also connected with the main antenna 01, and the two diversity receiving ports of the transceiver 05 are respectively connected with the duplexer 04, and the duplexer 04 is al...
