The microstrip antenna loaded with liquid metamaterials is presented in the manuscript. Liquid split ring resonator (SRR) is used as metamaterial inclusion in the antenna. Distilled water and sea water are the two liquids used one after another to form liquid SRR. The liquid metamaterial microstrip antenna is also compared with metal (copper) metamaterial microstrip antenna. The design results in the form of return loss, bandwidth and gain are compared. The tuning in the frequency spectrum is achieved by using liquids instead of metal as metamaterial. The gain of the antenna is also improved by loading it with liquid metamaterials. The frequency spectrum is tuned using liquid metamaterial loading compared with metal metamaterial loading.
