What types of GPS module antennas are there? What are the advantages of each?

The GPS module antenna is an essential structure for equipment that needs to receive or transmit signals. For example, the most frequently used devices such as mobile phones, radios, TVs, and drones contain GPS module antennas. Although we often come into contact with it, we know very little about this kind of antenna. Next, let’s learn together what types of GPS module antennas there are and what are the advantages of each?

1. Divided from polarization methods

GPS module antennas can be divided into vertical modules and circular modules in terms of design. As the name suggests, the difference between the two is the design arrangement of internal materials. Generally, the circular module has a wider signal reception and emission range, so the received signal is stronger and the use effect is better than the vertical module. Circular modules are also the form used by most equipment on the market.

2. From the installation method

The installation position of the antenna is different, and the GPS module antenna can be divided into built-in type and external type. As the name suggests, the external antenna type places the antenna outside the device. This method makes the device very large, which is not conducive to the transportation of the device and is not in line with the development trend. Now the trend of module antennas is towards miniaturization, and intensive development of internal antenna types has become the mainstream of design.

3. Whether there is an external power supply

With or without external power supply, GPS module antennas can be divided into active antennas and passive antennas, which are distinguished from the power supply method. The active antenna also has a signal amplifier, which requires an external power supply, and the signal reception effect is very good, while the passive signal does not have a signal amplifier or an external power supply, so the signal effect is greatly reduced.

There are many classification methods for GPS module antennas, and their application scenarios are also different.
