Abstract

The rapid evolution of GPS, mobile and wireless communication systems in the last years is based, substantially, on ceramic based dielectrics with effect on miniaturization of components (antennas, filters, oscillators), cost and temperature stability. The development of high dielectric constant materials was critical for the dimensions reduction of the equipment but also for their performance improvements. These materials have high dielectric constant, εr, between 20 and 90 ; low losses in microwave and millimetre wave domain and a low variation of dielectric constant with the temperature. The paper describes a high dielectric constant material, Barium Neodymium Titanate - (Ba,Pb)Nd2Ti5O14 (BNT), and presents some results obtained by using this ceramic based material to manufacture a dielectric resonator antenna..

Keywords
