One of perspective directions of a solid-state electronic engineering is producing new devices on the basis of ferrite-piezoelectric materials. Design and application of new microstrip microwave attenuator are considered.
A new class of electrically tunable microwave signal processing devices based on layered ferrite-piezoelectric structure is proposed. A trilayer magnetoelectric structure consisting of a lead magnesium niobate-lead titanate (PMN-PT) and yttrium iron garnet (YIG) film on gadolinium gallium garnet (GGG) substrate is considered. Design and experimental data of microstrip phase shifter are presented.
The design and characterisation of a miniaturised 100 MHz antenna based on magnetoelectric (ME) composites are discussed. Ferrite - ferroelectric composites with high and equal permeability mur and permittivity epsivr have been synthesised and used as the substrate for a microstrip antenna. The composite also facilitates impedance matching to free space. A sample of nickel zinc ferrite and bismuth...
