All GNSS antennas are meant to receive and amplify radio signals transmitted to certain frequencies from GNSS satellites and convert these into electronic signals to use. GNSS antennas help optimize the performance of your GNSS receiver. The variety of GNSS antenna types can make it harder to choose the right option for the needs of your application. The diversification of GNSS applications requires using different GNSS antenna types to meet the needs of each application.
Different GNSS antenna applications need different antenna types. We have described the most common types of GNSS antennas here to make things more understandable.
So, here we go:
A patch antenna is a type of directional antenna that operates in the microwave frequency range. It consists of a radiating patch placed over a ground plane with a dielectric material in between them. The patch can be square, circular, or rectangular in shape and can be designed for different frequencies depending on its dimensions. Patch antennas are commonly used in GPS receivers, cellular phones, and wireless communication systems due to their low profile and high efficiency.
A helical antenna is a type of antenna with a coil-shaped wire wound around a central rod. It is a popular choice for handheld GPS devices due to its compact size and good performance in high signal noise environments. The helix can be either right-handed or left-handed, and the number of turns and pitch angle can be adjusted to optimize its performance. Helical antennas are also used in satellite communication systems, weather monitoring, and military applications.
The choke ring antenna is a circularly polarized antenna used in GPS receivers. It consists of a cylindrical ring with slots cut into it, which provide a delay path for the incoming signals. This helps to mitigate multipath effects and is often used in areas with tall buildings or other obstructions. Choke ring antennas are commonly used in surveying, geodesy, and mapping applications.
A geodetic antenna is a type of high-precision antenna used in geodetic and surveying applications. Geodetic antennas are designed to provide highly accurate measurements of position and orientation, making them ideal for use in applications where even small errors can have significant consequences.
Geodetic antennas typically have a large diameter and are characterized by their high gain and low noise characteristics. This allows them to pick up weak signals from GPS and other GNSS satellites, even in areas with poor visibility or high levels of interference.
Geodetic antennas can be used in a wide range of applications, including land surveying, construction, mining, and oil and gas exploration. In each case, the accuracy and reliability of the antenna are critical factors in achieving the desired results.
We understand that GNSS antennas are popularly used in various applications ranging from mapping to surviving, military, and more. Regardless of the application you need a GNSS antenna for, Mide has various GNSS antennas. You can explore the GNSS antennas catalog here to make the best choice.
