Circular Polarization in mmWave Applications. Enhances Connectivity in 3 Aspects

,

The rise of mmWave (millimeter-wave) technology in communication systems has sparked significant interest due to its ultra-high-speed wireless connectivity. From 5G to emerging 6G networks, mmWave applications are shaping the future of telecommunications. In this context, circular polarization (CP) is vital in enhancing signal quality and overcoming challenges unique to mmWave communication. 

 

Introduction of mmWave Communication

Satellite-Connected Car

 

Satellite communication: In space-based networks, mmWave provides high-throughput communication channels for satellite-to-ground and inter-satellite links. 

 

Challenges Faced by mmWave Communication and How Circular Polarization Overcomes Them

mmWave offers a promising solution for many applications requiring high-quality networks, but it also comes with several challenges. 

 

Propagation loss: mmWave signals face higher propagation losses, particularly in urban environments where buildings and other obstacles block or reflect signals. Circular polarization can help maintain signal quality in environments with significant signal reflections and polarization mismatches. 

 

Multipath interference: In urban or indoor settings, mmWave signals often encounter reflections from walls, windows, and other surfaces, leading to multipath interference. Circular polarization significantly reduces the impact of multipath reflections, as its signal pattern minimizes destructive interference caused by these reflections. 

 

Polarization sensitivity: Currently, 5G mmWave communication systems use linear polarization, which can suffer from polarization mismatch if the transmitting and receiving devices are not perfectly aligned. Circular polarization mitigates this by allowing signals to be received regardless of device orientation, providing more consistent communication quality.

Why do LEO Satellite Antennas Utilize Circular Polarization?

,

Polarization is a key factor in antenna design, directly influencing performance and transmission efficiency. In LEO (Low Earth Orbit) satellite communications, array antennas are widely used, with circular polarization strategically employed. 

 

What is Antenna Polarization? 

Polarization refers to the orientation of an electromagnetic wave’s electric field vector. It describes how the electric field oscillates in a particular direction as the wave propagates. Based on the direction of the electric field vector’s oscillation, there are two main polarization types: linear and circular. 

Linear Polarization: The electric field vector oscillates along a fixed direction, such as horizontal or vertical. When the polarization directions of the transmitting and receiving antennas align, signal transmission efficiency is optimized. However, if the polarization directions differ, signal strength can diminish. Vertical or horizontal linear polarization antennas are commonly used in mobile communication systems. 

Linear Polarization

 

Circular Polarization: The electric field vector rotates in a helical pattern as the wave propagates, which can be either LHCP (Left-Hand Circular Polarization) or RHCP (Right-Hand Circular Polarization). Circular polarization helps to minimize signal attenuation caused by angular variations between the transmitting and receiving ends, making it particularly suitable for environments with movement, rotation, or multipath effects. Circular Polarization

 

Why Do LEO Satellites Use Circular Polarization? 

Circular polarization antennas reduce signal attenuation across various transmission paths, especially when satellites move rapidly. This enhances signal stability and communication efficiency. Here are three critical features of circular polarization. 

Reduce Polarization Loss: In LEO satellite communications, the satellite’s constant movement means that the transmission path and angle are not fixed. Linear polarization can lead to signal loss or attenuation due to the misalignment of polarization angles between the transmitting and receiving ends. 

 

Improve Multipath Interference Resistance: Circular polarization antennas effectively counter multipath effects, where signals reflect off different surfaces before reaching the receiver, potentially causing interference or signal distortion. Circular polarization maintains higher signal integrity across various reflection paths, thus improving signal quality. 

 

Reduce Path Loss: Atmospheric conditions like rain, fog, and ionospheric disturbances can degrade satellite signals. With its rotating electric field, circular polarization is less affected by these conditions than linear polarization. This makes it more effective at reducing path loss, especially in long-distance satellite communications, ensuring more stable and reliable signal transmission.
