    Abstract
    An amphibian antenna was constructed that is capable of radiating both above and below the surface of water. The antenna is effectively a dual band PIFA design where each radiating element is tuned to resonate in close proximity of either air or water. A tuning stub was switched into circuit by the use of a passive, water filled, capacitive microstrip switch. The antenna was designed to operate at 433 MHz and good input impedance was observed in both simulation and measurement for both environments.An amphibian antenna was constructed that is capable of radiating both above and below the surface of water.
