Types of gps antennas

With the rapid development of Global Positioning system (GPS) technology, GPS antennas, as the key equipment to receive GPS signals, are increasingly widely used. In this paper, the types of GPS antennas are introduced in detail, including their characteristics, application scenarios and advantages, so that readers can better understand the development status and future trend of GPS antennas.

Types of GPS antennas

1. Classify by structure

(1) Spiral antenna: spiral antenna is a commonly used GPS receiving antenna, which has the advantages of simple structure and low price. It is suitable for GPS positioning on mobile platforms such as vehicles and ships.

(2) flat panel antenna: flat panel antenna has wide bandwidth and good circular polarization characteristics, so it is suitable for GPS signal reception in various complex environments. It is widely used in handheld devices, measuring instruments and other fields.

(3) microstrip antenna: microstrip antenna has the characteristics of small size and light weight, so it is suitable for integration in mobile devices, and it is often used in portable navigation equipment, UAV and so on.

(4) Array antennas: array antennas are composed of multiple single antennas. Through optimal arrangement and combination, the receiving performance of GPS signals can be improved. It is suitable for high-precision positioning, aerospace and other fields.

2. Classification by use

(1) Civil GPS antenna: mainly used in general navigation, positioning, speed measurement and other civilian fields, this kind of antenna has low cost and wide applicability.

(2) Professional GPS antenna: mainly used in aerospace, geological survey, marine fishery and other high-precision fields, this kind of antenna has high performance and stability, and can meet the needs of high-precision positioning in complex environment.

(3) Special environment GPS antenna: GPS antenna designed for special environment, such as waterproof, explosion-proof, anti-corrosion, etc., this kind of antenna is suitable for GPS signal reception in extreme environment.
