New high-frequency hexagonal ferrite materials i) 900 MHz RFID Antennas ii) 94 GHz non-reciprocal switches

In this paper the development of two new hexagonal ferrite materials is reported: i) Barium hexaferrite materials for RFID antenna applications and reading distance enhancement at a frequency around 900 MHz ii) Strontium hexaferrite materials for non-reciprocal antenna switches in satellite communications at frequencies around 94 GHz.
