Experiments with liquid antenna

In this page we show some experiments with an eGaIn antenna in our lab.

You can watch some videos summarising the laboratory experiments:

  • The liquid length can be changed, adapting the antenna to work in different frequencies. See some examples of adpating a liquid monopole antenna and the transmission of a broadband OFDM signal in this link.
  • It is important to be able to change the liquid length and shape without the need of pumps. See some examples of experiments adapting the antenna operating frequency and moving the liquid with low-frequency EM fields in this link.

eEGaIn is a liquid metal at room temperature – watch it !
