Embodiment 1
[0064] Such as figure 1 As shown, it is a schematic diagram of the exploded structure of the antenna 100 in the first preferred embodiment of the present application. The antenna 100 includes a radiation piece 10, a radiation piece reference ground 11, a first transmission line 21, a second transmission line 22, a third transmission line 23, a fourth transmission line 24, a transmission line reference ground 211, a first connection part 31, and a second connection part 32 . The third connection part 33 , the fourth connection part 34 , the first power feeding part 41 , the second power feeding part 42 , the third power feeding part 43 and the fourth power feeding part 44 .
[0065] The radiating sheet 10 is used to transmit and receive radio frequency signals. The radiating sheet 10 can be specifically a copper sheet, or a copper foil attached to a board. The shape of the radiating sheet 10 can be set as required, such as being set as The symmetrical shape can also be set as...
Embodiment 2
[0104] Based on the same inventive concept, the present application also provides a communication device, such as Figure 14 As shown, the communication device 300 includes the antenna 100 in Embodiment 1 and the transceiver 200 for receiving signals from the antenna 100 or sending signals to the antenna 100 .
[0105] The above-mentioned communication device sets the first connecting part 31 opposite to the reference ground 11 of the radiating sheet, two first radiation feeding parts 411 located in a plane, and the first transmission line feeding part 412, based on inductive The characteristic strength is proportional to the distance, and the capacitive characteristic strength is inversely proportional to the distance. Since the distance between the first connecting part 31 and the reference ground 11 of the radiation sheet is greater than the distance between the first transmission line feeding part 412 and the The distance between the two first radiation feeding parts 411, ...
