Radome Design Guidelines
7.1
Effects of radomes on mmWave sensor performance
Radar waves are reflected at the radome boundary
Losses in total radar radiated or received power
The reflected wave enters the receiving channel, affecting the isolation between the transmitting and receiving
channels
Reflections may degrade the standing wave of the antenna, further affecting the antenna gain
Radar waves will suffer loss when propagated in the medium. In theory, the higher the frequency, the greater
the loss will be
Electromagnetic waves undergo a certain degree of refraction as they pass through a medium
Affects the antenna's radiation pattern, which in turn affects the sensor's coverage
7.2
Radome Design Principles
7.3
Common materials
Know the material and electrical
properties of the radome before
designing
The table on the right is for reference
only, please confirm the actual value with
the supplier
Height H from the antenna to the inner
surface of the radome
When space permits, 1x or 1.5x
wavelength is preferred
For example, 12.4 or 18.6mm is
recommended for 24.125GHz
Error control: ±1.2mm
Thickness D of the radome
Recommended half wavelength, error
control ±20%
If the thickness requirement at half
wavelength cannot be met
Low er materials are recommended
Thickness recommended 1/8
wavelength or thinner

Common material properties of radomes
Influence of heterogeneous materials or multi-layer composite materials on radar performance,
it is recommended to make experimental adjustments during design
