Hard Ferrites for High Frequency Antenna Applications

Abstract

Advances in wireless communication place an increasing number of demands on antenna performance, necessitating the presence of various capabilities in a single device. Reconfigurable antennas are frequently utilized to meet these various application demands within a restricted area. The purpose of this book chapter is to summarize general introduction about hard ferrites, different synthesis methods of ferrite for antenna application and altering functioning of antenna by reconfiguring them by ferrites. Along with this we have also focused on miniaturization and reconfiguration of antennas which is becoming a very important aspect of wireless communication devices. Miniaturization and reconfiguration of antennas involves a deliberate alteration in the form and/or electrical behaviour of the antenna, leading in a change in the antenna's functioning.
