摘要：
In this paper the propagation of electromagnetic waves in a medium with non zero conductivity is discussed, analyzing the dielectric properties of the sea water, in order to accurately characterize a wireless communication channel. Mathematical models for sea water dielectric constant, wavelength, propagation speed and path loss when an electromagnetic wave at 2.4GHz propagates through sea water are presented. A Bow-Tie microstrip antenna that is required to overcome the high path loss and bandwidth requirements in sea water is studied. A dual-band antenna, with arc-shaped circular slots, operating for IEEE802.11 b/g/n standards, at 2.4GHz and 5.1 GHz for WLAN communications, with dimensions 1.4 cm(2) is implemented. Return loss, input impedance and gain have been extracted in order to characterize antennas' performance in a conductive medium.
