CIMERA radomes protect antennas from environmental influences while maintaining their electromagnetic performance all around the world. It can be used in sub-6 GHz bands, and at higher frequencies up to 100 GHz. A fundamental property of those electromagnetic waves in regards of data transfer is their polarization. Additionally, their propagation is influenced by environmental factors. CIMERA radome can protect against attenuation and diffraction, enabling effective utilization of these frequencies.
Electromagnetic waves in general
Polarization is the direction of the electric field vector in an electromagnetic wave. The electric field vector can oscillate in any direction perpendicular to the direction of wave propagation. In some applications, such as satellite communication, circular polarization is used to maintain the signal quality regardless of the satellite orientation. Linear polarization, where the electric field oscillates in a fixed direction, is commonly used in radar applications.
Electromagnetic wave propagation at these frequencies can be affected by various factors such as atmospheric conditions, ground reflection, and diffraction. At higher frequencies, such as millimeter waves, the wave can experience a high level of attenuation due to atmospheric absorption. However, drawbacks as the surrounding weather can’t be controlled. Using CIMERA radomes is one of the few things which can easily be integrated and can help saving energy and signal loss.
In addition, the propagation of electromagnetic waves can be influenced by the presence of obstacles such as buildings, trees, and mountains. Diffraction is the bending of the wave around an obstacle, which can result in areas of reduced signal strength or shadow zones.
Frequency bands of CIMERA radomes – 1 Ghz to 100 GHz and above
CIMERA radomes are used for frequencies above 1 GHz up to 100 GHz and above offering great mechanical stability and electromagnetic performance particularly at millimeter wave frequencies. Below are the IEEE, NATO and ITU frequency bands displayed for which CIMERA radomes are used:
In the field of 12 GHz to 40 GHz different frequency bands fall within this frequency range. For example, the Ku-band from 12 to 18 GHz, the K-band from 18 to 26.5 GHz and the Ka-band from 26.5 GHz to 40 GHz. Within these bands our CIMERA radome is used for 5G antenna applications or satellite communication antennas.
Higher frequency applications ranging from 76 GHz to 81 GHz are widely accepted as the preferred frequency band for automotive radar applications, where our CIMERA radomes are well-suited because of the great RF performance in combination with optimal mechanical strength.
The millimeter wave frequencies used for applications like satellite communication, automotive radar and sensing, offer numerous advantages, such as high data rates, low latency, and high bandwidth. However, these frequencies are highly susceptible to environmental factors such as rain, snow, and dust. CIMERA Radomes are designed to protect against these environmental factors with its high mechanical strength and hydrophobic surface while maintaining the electrical performance of the antenna beneath it.
Overall, the use of frequencies between 1 GHz and 100 GHz and above allow for high data rates and accurate sensing capabilities. The polarization of the signal is important for maintaining signal quality in various applications, and the propagation of electromagnetic waves is influenced by a variety of environmental factors. With the use of advanced technologies – with the CIMERA radome, these frequencies can be utilized effectively in a range of applications, from sub 6GHz to satellite communication, automotive radar and sensing.
