3D printed ceramic antenna is new technology. 3D structured ceramics using additive manufacturing with very solid ceramic materials with low dielectric losses so anyone interested in producing and testing their antenna can. Below we discuss materials used in this technology, and how an antenna benefit from this process?
We also provide a Case Study describing the fabrication of new geometries to enhance its performance.
Firstly, it is true this technology has been used by engineers and designers to push current antennas and RF electronics design and development. Now it is available for a wider audience.
Indeed, you can 3D print your own working antenna. If this interests you it means you are going to be able to develop your own antenna with materials that have amazing properties. So it is certainly possible for engineers, designers, students and hobbyists alike to be involved in antenna product development. 3D printing provides the opportunity for anyone to create a design and fabricate it.
There are materials with various dielectric properties interesting for fabricating antennas. It is possible to produce parts in a new range of filaments each with different permittivity going from 2.2 for the lowest up to 7.5 for the highest suitable for RF applications. These material products are also characterised by their low dielectric losses, their high heat resistance for enduring up to 115 deg HDT. They are suitable for RF Microwave applications including in the avionics and space environment.Evaluate my part

It is also possible to use monolithic materials. Below the combined use of metal and ceramic provides a breakthrough development.
One domain where this new technology has great potential is with antenna applications. It makes a very compact antenna with good radio and mechanical properties. This hasn’t previously been possible.
A recently closed TDE activity with Anywaves in France wanted to develop, test and qualify 3D Printed (SLA) Ceramic Antenna structures. As such, the activity proposed to develop, manufacture and test four antennas.
Anywaves produced two elliptical antennas with a filled lattice structure ad two truncated patch antennas with an empty lattice structure.
The testing of the four antennas proved that this new technology can reach expected radiofrequency performances. It requires a slight shift in frequency as the cleaning of the material as part of the industrial process.
The 3D Printed Ceramic Antenna also surpassed expectations under very demanding environmental tests. Therefore demonstrating good mechanical (low dielectric losses) and thermal properties throughout. This is especially the case with the patch antenna with an empty lattice.
Beyond DRA and patch antenna, there are plans to investigate more complex designs. With further exploration into the industrialisation of the process. Safe to say 3D structured dielectric material is an exciting technology for space development in the future.
