[0021] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0022] like Figure 1 to Figure 2 As shown, a 433 MHz antenna includes a PCB 1 and a steel sheet antenna 2.

[0023] PCB1 is set at the bottom of the product and has been debugged.

[0024] A pin 21 is provided at one end of the steel sheet antenna 2 .

[0025] The PCB 1 is provided with welding holes 11 .

[0026] The pins 21 of the steel sheet antenna 2 are inserted into the welding holes 11 on the PCB 1 .

[0027] The pins 21 are perpendicular to the steel sheet antenna 2 .

[0028] The steel sheet antenna 2 is parallel to the PCB 1 .

[0029] There are traces on the PCB 1 to form a circuit, and the welding holes 11 are located on the circuit.

[0030] There is copper cladding in the welding hole 11, and the copper cladding is connected to the circuit.

[0031] The size of the pin 21 is smaller than the size of the welding hole 11 .

[0032] The pins 21 of the steel sheet antenna 2 are inserted into and soldered to the soldering holes 11 on the PCB 1 .

[0033] The utility model provides a 433MHz antenna, which adopts a structural form of a combination of PCB and steel sheet in a small-size environment to solve the problem that the antenna size is not enough to meet the performance requirements. A steel sheet antenna is added on the basis of PCB, which has a better use in height, so that the antenna performance can meet the requirements.

[0034] The utility model provides a 433MHz antenna, which uses a debugged PCB1 at the bottom of the product. There are traces on the PCB1 to form a circuit. When current passes through the circuit of the PCB1, it will radiate a signal, and the signal cannot meet the 433M standard because the PCB trace is not long enough. Based on this situation, a welding hole 11 is set on the circuit of the PCB1, and there is copper in the hole. The copper in the hole and the circuit of the PCB1 are connected. In addition, a steel sheet with a suitable shape is designed as a steel sheet antenna 2. One end of the steel sheet antenna 2 is bent to form a pin 21. The size of the pin 21 is smaller than the welding hole 11 on the PCB1. 1. Insert the pin 21 of the steel antenna 2 into the welding hole 11 on the PCB1, and solder the pin 21 of the steel antenna 2 in the welding hole 11 of the PCB1 with solder. The steel antenna 2 and the PCB1 are in parallel, and the circuits of the steel antenna 2 and the PCB1 are connected through the welding hole 11. When the antenna current flows through the circuit of the PCB1 and the welding hole 11 into the steel antenna 2, the PCB1 and the steel antenna 2 form a whole, which increases the radiation size of the overall antenna and reaches the antenna performance requirement of 433M, thereby realizing the miniaturization of the antenna and ensuring the stable working frequency of the antenna.

[0035] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
