With the development of science and the upgrading of global positioning system, GPS antenna in the field of professional and business, such as exploration of science and technology,convoys, military tracking and other consumption products occupy very important position, then what is the function of it?
The first function is to capture satellites and receive satellite positioning information, which is radiation and electromagnetic waves. Any high frequency circuit which is not completely shielded can radiate electromagnetic waves more or less to the surrounding space, or receive electromagnetic waves more or less from the surrounding space.
The second function is to change the electromagnetic energy of radio signal sent by the satellite into the current that can be absorbed by the electronic device of the receiver, it is the energy conversion. For the special equipment or car equipment, the equipment and GPS receiver module before tend to have a certain distance, so in a real environment more than 1 meter of feeder cable may be used, but as there are many signal loss for feeder cable, so in this environment can only choose active GPS antenna.
After reading the above information, you may have a certain understanding of the function of GPS antenna. For more questions, please email us info@rfsupplier.com for professional service.
