Aluminium phosphate ( AlPO 4 )-Magnesium fluoride ( MgF 2 ) composite has been prepared through solid state ceramic route. The formation of composite has been confirmed by X-ray diffraction studies. The variation in ε r and tanδ of the composite with frequency in the range (1K Hz – 3 MHz) has been studied. The AlPO 4 - MgF 2 has a small temperature dependence of ε r . The composite shows low relative permittivity of 3 and low dielectric loss (tanδ = 7×10 −3 ) at 5.85 GHz.
