Innovations in Satellite Antennas Revolutionizing Global Connectivity

Highlights:

• Introduction
• Emerging trends in satellite antennas
• Cobham Satcom’s new satellite antennas
• Key acquisitions in the industry

In today’s highly interconnected world, satellite antennas play an important role in global communication. They also enable various crucial functions starting from television broadcasts and internet connectivity to weather monitoring and military operations.

A satellite antenna is a device mainly responsible for receiving or transmitting high-frequency electromagnetic waves from the Earth to satellites that orbit in free space. Then the device adapts these frequencies to distribute over coaxial cable networks. Traditionally, satellite antennas were large, cumbersome, and limited in their capabilities. However, continuous technological advancements have revolutionized their design, efficiency, and application.

Advances in satellite antenna technology resulting in robust communication

In recent years, the rise of phased array antennas has revolutionized satellite communication. Unlike traditional parabolic antennas, phased array systems use multiple small antenna elements to steer beams electronically. This eliminates the need for mechanical movement, resulting in faster response times and greater reliability. Electronically steered arrays (ESAs) and flat panel phased array antennas are gaining huge popularity in various applications starting from mobile communications to aerospace.

Furthermore, the demand for compact and portable communication solutions is driving the miniaturization of satellite antennas. Micronized antennas, which are smaller and lighter than traditional models, are increasingly popular. These antennas are ideal for deployment on Unmanned Aerial Vehicles (UAVs), aircraft, and portable communication devices, making satellite communication more accessible and versatile.

These days, antennas are developed with multi-band and multi-orbit capabilities. As satellite networks expand into different orbits, including Low Earth Orbit, Medium Earth Orbit, and Geostationary Earth Orbit, antennas capable of switching between these orbits are becoming essential. Multi-band antennas, which operate across various frequency bands (such as Ku, Ka, L, and S bands), offer greater flexibility and performance, catering to diverse communication needs.

Moreover, integration of modern technologies has also played a significant role in enhancing the signal quality and efficiency of satellite antennas. Modern antennas utilize artificial intelligence algorithms to optimize their performance in real-time. These intelligent systems automatically adjust to changing conditions, enhancing signal strength and quality. Techniques like beamforming and Multiple Input Multiple Output (MIMO) are also enhancing signal quality and data rates, making satellite communication more robust and efficient. Also, incorporating 5G technology and IoT in these antennas has improved connectivity. These advanced antennas are developed to support both terrestrial and satellite networks, offering seamless connectivity for mobile devices and promoting several IoT-based applications.

Cobham Satcom’s new satellite antenna for enhancing maritime communication

In March 2024, Cobham Satcom, a leading global technology and services innovator launched its new satellite antennas, namely, SAILOR XTR TVRO antennas for boosting maritime satellite communication. The company’s satellite models - SAILOR XTR 100 TVRO and SAILOR XTR 120 TVRO are designed by combining decades of in-house expertise from Cobham Satcom’s market-leading Sea Tel TVRO portfolio with the latest innovations in maritime satellite communication from the SAILOR XTR VSAT platform. These antennas introduced new capabilities and enhanced performance levels for a wide range of vessel types including superyachts, cruise ships, and merchant vessels.

Key strategies of Thales and MDA to lead in the field of satellite communication

In May 2024, Thales, a global technology leader announced its acquisition of Get SAT, leading provider of micronized satellite communication terminals. With this acquisition, Thales aims to strengthen its product offerings across various sectors including defense, civil aeronautics and emergency services sectors with best-in-class satellite connectivity technology. By signing this agreement with Gen SAT, Thales is securing its position on aircraft flying significantly.

Similarly, in August 2023, MDA, a leading Canadian space technology company acquired the digital payload division of SatixFy, renowned provider of Satellite and Quasi-Satellite communication technology. This acquisition helped MDA strengthen its position in the landscape of digital satellite technology solutions. Along with this, the digital payload team worked with its satellite systems business in Montreal to advance MDA’s new digital satellite product offering. Under this acquisition, the companies worked together to solidify their positions and address the growing consumer demands by capitalizing on the Low Earth Orbit (LEO) satellite communication market.  

To wrap up, the increase in the demand for robust satellite communications from defense and intelligence agencies for tactical needs is expected to boost the growth of the satellite antenna industry in the coming era. Moreover, the ongoing development of sophisticated antenna technologies to strengthen the capabilities of satellite services is predicted to create lucrative opportunities for the landscape in the future.
