Description

technical field [0001] The invention relates to antenna technology, in particular to an antenna circuit and electronic equipment. Background technique [0002] The main diversity technology is widely used in mobile terminals. The main antenna is generally connected to the main radio frequency circuit and is responsible for the transmission and reception of radio frequency signals. The diversity antenna is generally connected to the diversity radio frequency circuit and is only responsible for the reception of radio frequency signals. refer to figure 1 , figure 1 It is a schematic diagram of the antenna circuit in the prior art Figure 1 , the antenna circuit includes a main set chip, a diversity chip, a main set antenna 1, a diversity antenna 1, and a double-pole double-throw switch, through which the radio frequency path of the main set chip can be connected to the main set antenna 1 or the diversity antenna 1. The radio frequency channel of the diversity chip can also b...

Problems solved by technology

refer to figure 1 , figure 1 It is a schematic diagram of the antenna circuit in the prior art Figure 1 , the antenna circuit includes a main set chip, a diversity chip, a main set antenna 1, a diversity antenna 1, and a double-pole double-throw switch, through which the radio frequency path of the main set chip can be connected to the main set antenna 1 or the diversity antenna 1. The radio frequency channel of the diversity chip can also be connected to the diversity antenna 1 or the main antenna 1 through the double pole double throw switch; knife double throw switch, and then loop back to the diversity antenna 1, the wiring path is long and the signal loss is large; in addition, it also takes up more printed circuit board (PCB, Printed Circuit Board) wiring area

[0004] refer to figure 2 , figure 2 It is a schematic diagram of the antenna circuit in the prior art Figure II , the antenna circuit includes a main set chip, a diversity chip, a main set antenna 1, a main set antenna 2, a diversity antenna 1, and a three-pole three-throw switch, through which the two radio frequency paths of the main set chip can be connected respectively To any two of the main antenna 1, the main antenna 2, and the diversity antenna 1; through the three-pole three-throw switch, one RF path of the diversity chip can also be connected to the diversity antenna 1, or the main antenna 1, or the main antenna Antenna 2; the disadvantage of this solution is that although it solves the problem of adding a radio frequency path and a main antenna to the main set chip, it still does not solve the problem of the routing of the diversity radio frequency path; Antenna, still can't switch
