In the world of the Internet of Vehicles (IoV), satellite connectivity is regarded as one key technology for enhancing the smart cockpit experience. How to integrate the user terminal, which receives and transmits satellite signals, into the car without affecting the user experience has become a challenge. 

What Type of Antenna Will Be Used in the Satellite-Connected Car?  

In the domain of satellite communication, the two commonly utilized types of antennas for user terminals are dish antennas and phased array antennas. Compared to dish antennas, the physical properties of phased array antennas enable them to integrate with planar interfaces such as liquid crystal panels or other flat materials. This means that phased array antennas have the potential to be thinner and flatter, allowing them to be integrated into structures such as car sunroofs or other flat surfaces without compromising their functionality. 

YTTEK’S Vision of Satellite-Connected Car Antennas 

With over a decade of solid experience in high-frequency wireless technology, YTTEK successfully collaborated with the Taiwan Space Agency (TASA) to capture cosmic signals. In partnership with a renowned liquid crystal display manufacturer, we develop an exclusive liquid crystal Reconfigurable Intelligent Surface (RIS) system.  

These collaborations give us the foundation to envision a future where the antenna of the satellite-connected car is seamlessly integrated into car sunroofs in a transparent form like the liquid crystal panel used in the RIS system. This would perfectly incorporate satellite connectivity into the car without affecting the user experience. 

In our pursuit of satellite-connected cars, we have also completed an experimental LEO satellite communication system for cars. This research has given YTTEK deeper insights into the feasibility of our vision. 

YTTEK offers comprehensive system integration solutions in wireless communication, including algorithm optimization, baseband signal processing, and phased array antenna design. These core capabilities indicate that in addition to antenna design, YTTEK offers the RF front-end system to provide a complete solution, enabling YTTEK to advance further in satellite-connected cars. 

Signal interference poses a significant challenge in unmanned aerial vehicle (UAV) communications. Frequency hopping technology has emerged as an optimal solution to address this issue. 

What is Frequency Hopping? 

Frequency hopping is a wireless communication technology that rapidly switches communication signals between different frequencies to mitigate signal interference. In Frequency hopping, communication signals hop between frequencies on the frequency axis, with each data packet or interval transmitted at different frequencies. This frequency-hopping pattern is determined by a pre-agreed pseudorandom sequence. 

Frequency Hopping

The Benefits of Frequency Hopping 

Frequency hopping technology offers several advantages, including resistance to interference, security and covert operations, and spectrum efficiency.  

• Resistance to interference: Due to the rapid frequency hopping of communication signals, it can effectively resist malicious interference and eavesdropping.  
• Security and covert operations: Because the frequency hopping pattern is based on a pseudorandom sequence, communication signals are difficult for unauthorized recipients to capture and comprehend, thereby enhancing communication security and covert operations. 
• Improves spectrum efficiency: A frequency hopping transmitted radio signal can share frequency bands with conventional transmissions without causing significant interference, thus enhancing spectrum efficiency. 

Application of Frequency Hopping 

Frequency hopping is currently employed in Bluetooth, unmanned aerial vehicles (UAVs), and other military applications. Due to its resistance to interference, security, and covert operation, this technology is particularly suitable for UAV communications. 

Unmanned Aerial Vehicle (UAV)
