Description

Technical Field

[0001] This utility model relates to the field of GPS antenna technology, specifically to satellite navigation receiving antennas. Background Technology

[0002] GPS is a terminal that uses satellite signals for positioning or navigation. Receiving these signals requires an antenna. GPS satellite signals are divided into L1 and L2, with frequencies of 1575.42MHz and 1228MHz respectively. L1 is an open civilian signal with circular polarization and a signal strength of about 166 dBM, which is relatively weak. These characteristics necessitate the use of a dedicated antenna for receiving GPS signals. The GPS receiving antenna is a sub-part of the clock system's signal receiving section, used to receive GPS satellite signals.

[0003] Traditional GPS antenna installation methods typically involve directly mounting the antenna onto the surface of the carrier. This makes it impossible to adjust the antenna's position, making it inconvenient to carry, bulky during transport, and affecting efficiency, which can easily lead to problems with usability.

One end of the second support arm 23 is hinged to the back plate 24 through the damping pivot 25.

[0022] Specifically, the fixed dark box 21 has fixing holes 26 around its bottom and finger positions 27 on its top.

[0023] In this embodiment, the support component 2 is fixed to the surface of the carrier by means of fixing holes 26 and screws. The finger position 27 is designed to make room, mainly to leave room for operation, so as to make it easier to remove the antenna body 1 from the fixing box 21.

[0025] In this embodiment, the outlet 28 is designed to allow for the connection of the cable 14 on the antenna body 1 to the power supply or control system.

[0026] Specifically, a magnet 29 is embedded in the back plate 24, and an iron sheet 15 is bonded to the bottom surface of the antenna body 1, and is magnetically attached to the back plate 24 by the iron sheet 15 and the magnet 29.

[0032] In use, the antenna body 1 (the internal low-noise signal module 12, also known as LNA, is the part that amplifies and filters the signal. The LNA can amplify the weak signal received by the antenna from the air, making it reach the strength that the receiver can process. Since the GPS signal is very weak, directly processing these signals will result in a very low signal-to-noise ratio. Therefore, it needs to be amplified by the LNA. The ceramic antenna 13, also known as a passive antenna, dielectric antenna, or patch, mainly receives and processes GPS satellite signals to achieve ground positioning) and the support assembly 2 are used together. The fixed dark box 21 in the support assembly 2 is used to store the antenna body 1.
