Antennas
An antenna is an electrotechnical device used to receive or transmit radio waves. Antennas are one of the basic elements of wireless communication. They found their use in radio and television broadcasting, but nowadays they are mainly used for the operation of mobile phones (GSM), wireless Internet (Wi-Fi) and navigation (GPS).
GSM antennas
GSM antennas (Global System for Mobile Communications) are a basic part of wireless communication systems that use the GSM standard to connect to the mobile network. GSM antennas play a key role in facilitating communication between a mobile device and the nearest GSM cell tower.
We usually differentiate between two main types of GSM antennas: internal and external. Internal antennas are built into the device itself and are commonly found in smartphones and other mobile devices. External antennas are individual units that are connected to a device using a coaxial cable and are often used by industrial, commercial, and military applications that require an increased signal range or power.

The primary function of the GSM antenna is to transmit and receive radio frequency (RF) signals between the device and the nearest cell tower. GSM antennas are designed to operate in specific frequency ranges, such as the 900 MHz and 1800 MHz bands, and must be tuned to match the frequency band that is used by the cellular network.
The performance of a GSM antenna largely depends on its construction, including its shape, size and material used. Some GSM antennas are designed for omnidirectional coverage, while others are directional, providing higher gain and longer range in a specific direction.
GSM antennas are a critical component in wireless communication systems that use the GSM standard. They facilitate communication between a mobile device and the nearest cell tower and play a key role in the performance and quality of a mobile network connection.
GPS antennas
GPS antennas are a key part of wireless communication for GPS systems. The main task of GPS antennas is to receive the signal from the GPS satellites and transmit it to the receiver, which determines the position.
Use of GPS antennas
GPS antennas find their use in many applications, for example:
- Cars: GPS antennas are often included in car navigation systems and allow displaying the location on the map and navigation instructions.
- GPS devices: GPS antennas are a key part of GPS devices, such as GPS watches, GPS trackers or GPS locators.
- Research and cartography: GPS antennas are often part of research and cartography systems that are used for the identification of location and accurate mapping.
- Drones and aerial devices: GPS antennas are often part of drones and other aerial devices that use GPS for positioning and navigation.
- Monitoring and automation devices: GPS antennas are often used in monitoring and automation devices, such as measuring instruments or control units, to enable the identification of location.
GPS antennas must be properly installed and set to ensure accurate and reliable identification of location.
5G antennas
5G antennas are a special type of antenna designed to work with the 5G network. Their task is to transmit the signal between 5G network devices. 5G antennas are designed to work on higher frequency bands than antennas used for previous generations of mobile networks, such as 3G or 4G.
What principle do the 5G antennas work on?
5G antennas receive and transmit radio signals in higher bands, which allows them to transmit and receive more data faster. To ensure reliable communication, the 5G network requires rather a dense network of small cells and antennas instead of large telecommunications towers. That's because 5G transmissions can be easily blocked by buildings and other obstacles, so a dense network of small cells and antennas will help ensure a strong and reliable signal.
5G technology features high capacity and low connection latency and enables data transfer at a speed of up to 20 Gb/s, with a response time at the millisecond level. 5G technology also uses the concept of "network slicing", thanks to which the network environment can be adapted to the specific requirements and needs of devices and applications. This leads to the use of new applications and services such as virtual reality, autonomous vehicles, or the Internet of Things.
Advantages of 5G antennas
The main advantages of 5G antennas are better reliability and availability of the network and the ability to transmit and receive large data volumes faster, which enables the operation of applications and services whose operation was not possible with previous generations of networks.
4G antennas
In the past, 4G technology was the most widely used wireless network for mobile phones. It is still used around the world because it offers a fast and reliable wireless connection.
4G antennas are types of antennas designed to work with the 4G network. Their job is to transmit and receive signals between devices connected to the network and the 4G network infrastructure. In comparison with previous generations of mobile networks, such as 2G, 3G or 4G, they enable faster and more efficient data transfer. 4G antennas operate at higher frequencies than antennas of previous generations of mobile networks and therefore transmit data better. There are either internal or external 4G antennas. Internal antennas are found in devices such as mobile phones or tablets. External antennas are installed outside the equipment and are commonly located on telecommunication towers or buildings.
4G antennas enable fast data transfer and thus ensure the use of new applications and services, the operation of which would not be possible with previous generations of mobile networks. This includes, for example, streaming high-definition videos, playing online games, and fast Internet browsing. In addition, 4G antennas are also important for sectors such as healthcare and industry. 4G antennas enable the connection of sensors and other devices that ensure real-time status and operation monitoring.
Wi-Fi antennas
Wi-Fi antennas are an important element of wireless networks. Their main task is to enable the connection of devices to the Wi-Fi network and ensure reliable and fast data transfer.
Types of Wi-Fi antennas
There are two main types of Wi-Fi antennas: internal and external. Internal antennas are built into devices such as laptops, tablets, or mobile phones. External antennas are separate devices that can be connected to a device or placed on the wall or roof of a building. Wi-Fi antennas operate at different frequencies and have different gain factors that determine their performance and range. The greater the gain factor of the antenna, the greater the range and reliability of the Wi-Fi connection.
Advantages of Wi-Fi antennas
One of the biggest advantages of Wi-Fi antennas is their ability to enable a wireless connection to the Internet. Thanks to this, users can connect to the Internet from any place with an available Wi-Fi signal. This means that Wi-Fi antennas enable a flexible and convenient connection to the Internet, which is important for both homes and businesses.
In addition, Wi-Fi antennas positively affect the quality and reliability of the Wi-Fi connection. They are designed to provide a strong and reliable signal and minimize interference. Users thus have a fast and stable Wi-Fi connection for various activities, such as streaming videos, playing games or browsing the Internet.
