Problems solved by technology
In addition, there are more and more carrier aggregation (CA) requirements in various frequency bands in terminal design. If only one antenna is used, the CA requirements are all provided by the RF backend (the RF backend includes RF circuits, including RF switches, dual device, etc.), it will cause a large link loss

The invention provides a dual-antenna system suitable for a three-segment metal body. The system comprises a PCB, wherein a first metal body and a second metal body are respectively arranged on the PCB, the first metal body and the second metal body are connected by a first grounding part and a second grounding part, a gap is arranged between the first grounding part and the second grounding part, a first open slot antenna with an open edge is formed among the first metal body, the first grounding part and the second metal body, and a second open slot antenna with an open edge is formed among the first metal body, the second grounding part and the second metal body. The invention further provides a mobile terminal. Compared with the prior art, the open slot structure is formed between the two metal bodies to constitute two open slot (slot) antennas, one antenna is an intermediate frequency antenna, and the other antenna is a high frequency antenna, therefore radio frequency link loss can be reduced, the cost of the radio frequency back segment is also reduced, and the radiation performance index of the overall antenna is improved.
Description
technical field [0001] The invention relates to antenna technology, in particular to a dual-antenna system suitable for a three-section metal body and a mobile terminal. Background technique [0002] At present, more and more terminals adopt a three-section metal body design, and basically adopt traditional antenna designs such as inverted-F (IFA (Inverted-F Antenna)), loop (LOOP) or monopole (monopole). In addition, there are more and more carrier aggregation (CA) requirements in various frequency bands in terminal design. If only one antenna is used, the CA requirements are all provided by the RF backend (the RF backend includes RF circuits, including RF switches, dual device, etc.), it will cause a large link loss. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a dual-antenna system and a mobile terminal suitable for a three-section metal body, thereby reducing link loss. [0004] The invention...
