I am looking for some metal alloys that are either flexible in their solid-state or liquid metal alloy at room temperature and are applicable for patch antenna fabrication up to 20 GHz of the resonant frequency.
For patch antennae around 20 Ghz one would use commercial substrate with a thin layer e.g. of copper in the meantime there are VERY thin thus very flexible substrates (even to be worn on the human body) available..since just a thin layer of metal would not really help you ..too fragile)
Fritz Caspers Thank you, sir, for sharing your idea. It might be helpful, but I am looking for some materials that will be deformable at any of its thickness like Ga, EGaIn, EGaInSn etc.
you can also use fabrics (and that had been discussed in the literature) with very fine woven wires as part of the fabric..
