Abstract
The present disclosure relates to a radome for protecting an antenna assembly. The radome comprises a body made of dielectric material, wherein the body is configured to redirect at least a portion of waves emitted by the antenna assembly. The present disclosure further relates to antenna systems including such a radome, and to methods of manufacturing such radomes.
Claims20
A radome for protecting an antenna assembly, the radome comprising:
- a body made of dielectric material,
- wherein the body is configured to redirect at least a portion of waves emitted by the antenna assembly and is configured to reduce grating lobe levels of the antenna assembly and to improve gain of the antenna assembly in a selected direction.
A radome for protecting an antenna assembly, the radome comprising:
- a body made of dielectric material, wherein
- the body incorporates one or more internal structures configured to redirect at least a portion of waves emitted by the antenna assembly, wherein
- the internal structures have a first refractive index and a surrounding portion of the body of the radome has a second refractive index.
An antenna system comprising:
- an antenna assembly;
- and
- a radome configured to protect the antenna assembly, wherein
- the radome comprises a body made of dielectric material, and a matching layer, wherein
- the antenna assembly is configured to emit electromagnetic waves, the electromagnetic waves including a main beam and on or more grating lobes, and wherein
- the body is configured to redirect at least a portion of the electromagnetic waves emitted by the antenna assembly to reduce grating lobe levels of the antenna assembly.
