What is the role of GPS antennas, which play an "important role"?
As we all know, GPS is mainly a terminal product that receives satellite signals and then locates or navigates. During the process of receiving the antenna signal by GPS, the antenna must be used. GPS satellite signals are divided into L1 and L2, with frequencies of 1575.42MHZ and 1228MHZ, respectively, of which L1 is an open civil signal and the signal is circularly polarized. The signal strength is about -166dBW, which is a relatively weak signal. It is precisely because of these characteristics that GPS signal reception requires special antennas.

Types of antennas for antenna knowledge sharing (Part 2)
Long and medium waves propagate by earth and sky waves, which are continuously reflected between the ionosphere and the earth. According to this propagation characteristic, long and medium-wave antennas should be able to generate vertically polarized radio waves. Among the long and medium wave antennas, the more widely used vertical type, inverted L type, T type, umbrella type vertical grounding antenna. Long and medium wave antennas should have a good ground network. There are many technical problems in long and medium wave antennas, such as small effective height, small radiation resistance, low efficiency, narrow pass band, and small directivity coefficient. In order to solve these problems, antenna structures are often very complex and very large.

Types of antennas for antenna knowledge sharing (Part I)
Antenna is an indispensable part of wireless transmission, in addition to our use of optical fiber, cable, network cable, etc. to transmit wired signals, as long as it is in the air using electromagnetic wave propagation signals, various forms of antennas are required.
