GPS Antenna
Description
GPS antennas are mainly used to receive and transmit GPS signals. They are widely used in navigating and positioning equipment, vehicles and handsets. We can offer various antennas and attachments, such as active antennas, passive antennas, cables, connectors, and so on.
Jinchang has developed various kinds of GPS antennas. Different LNA solutions and housings are provided to meet customers’ requirements on antenna’s appearance and mounting. There are three mounting methods: adsorbing with magnet, pasting with adhesive and fastening with screw. Magnet mounting is simple and convenient, because it can be adsorbed directly when there is a metal plate. Adhesive mounting has wide application range. For screw mounting, we now can offer three screw models: M10, M12 and M20.
A whole set of GPS antenna includes ceramic patch, LNA (low noise amplifier), cable, connector and housing (covering). GPS patch is the key part of the antenna. The patch sizes we can offer include 10 mm × 10 mm, 12 mm × 12 mm, 15 mm × 15 mm, 18 mm ×1 8 mm, 25 mm × 25 mm, 35 mm × 35 mm, etc.
Advantages
1. Each product has been through five layer tests and FAQ sampling investigation. The first pass yield is 99%.
2. Our GPS antennas feature high gain, low loss and strong capability of receiving signals.
3. Protection grade is IP67 (ingress protection rating 67), which means our antennas are water proof.
4. The antenna is with corrosion resistance. It has passed 48 hours’ salt spray test.
Classification
1. Passive antenna and active antenna
2. Pre-filter antenna and post-filter antenna
3. First amplification antenna, second amplification antenna and third amplification antenna
4. High water proof degree antenna (IP68), general water proof degree antenna (IP67) and non water proof antenna
