The electrical properties of important organ tissues of chicken are presented to understand the electromagneticpropagation characteristics and its biomedical application in biological systems. Measurement of dielectric constant, conductivity, resistivity and loss tangent have been carried out at frequency range 8.2-12.4 GHz on X-Band microwave bench using infinite sample method, which involves mounting of the sample in a rectangular waveguide system excited in the TE10 mode. The result shows that for all organs the dielectric permittivity decreases with frequency whereas conductivity increases with frequency. The dielectric constant and conductivity decreases with the increase of total solid content of the tissues. For higher water content tissues, loss tangent is found to be higher compared to low water content tissues, whereas the resistivity value increases with increasing the solid content of tissues.
