What is the function of a suction cup antenna?

The main function of a suction cup antenna, like a regular antenna, is to radiate and receive radio waves. The suction cup antenna is fixed in a certain center by passing the antenna through the bottom suction cup to prevent unexpected situations. Due to its relatively stable suction cup base, it is applied to vehicles. In the wireless module industry, suction cup antennas are often used in conjunction with wireless modules to increase the communication interval between them. The working principle of an antenna is to transmit high-frequency current

Due to its relatively stable suction cup base, it is applied to vehicles. In the wireless module industry, suction cup antennas are often used in conjunction with wireless modules to increase the communication interval between them.
The working principle of the antenna is to convert high-frequency current into electromagnetic waves during transmission; When accepted, convert electromagnetic waves into high-frequency currents.
Device precautions:
The surrounding environment has a significant impact on the use of antennas, requiring no obstruction from buildings up to the left and no strong electromagnetic interference in the surrounding space. Only in this way can the suction cup antenna radiate and receive distant signals.
When using in conjunction with wireless modules, attention should be paid to the following guidelines to ensure better communication intervals for the modules:
1. Try not to get the antenna close to the ground and keep the surrounding area away from obstacles as much as possible
2. When using a suction cup antenna, try to straighten the leads as much as possible, and the suction cup base should be attached to a metal object.
