The design of a millimeter-wave reflector based on the ferroelectric ceramic was elaborated and considered. Among the advantages of the proposed design are simplicity and cost-effectiveness compared to devices based on active repeaters and reflectarrays. The use of ferroelectric ceramic in the reflector design allows operating in a wide frequency range up to 100 GHz. Parameters of ferroelectric ceramic were experimentally measured and used in the electromagnetic simulation of the proposed reflector. Simulation of the reflector’s radiation pattern demonstrated the effective beam scan possibility in a range of 35 deg.

Millimeter waves are increasingly used in modern telecommunication systems for wireless data transmission. However, higher path loss, especially caused by non-line-of-sight scenarios, remains challenging. The design of an electrically controllable reflector for the millimeter-wave range is elaborated and presented in this manuscript. The reflector design was based on distributed ferroelectric ceramic elements and could be used in a frequency range up to 100 GHz. The issue of the ferroelectric reflector impedance matching was analyzed in detail. Two possible implementations of the reflector for indoor and outdoor communication systems were considered and simulated. The prototype of the proposed reflector for an operating frequency of 60 GHz was manufactured. Both simulation and measurement results demonstrated the beam steering by the proposed ferroelectric reflector.

This article provides the results of an experimental investigation of characteristics of thin-films transparent electrodes deposited on ferroelectric ceramic plates. The experimental investigation of parameters of ZnO and resistive alloy of Si-Ti-Ce deposited on ferroelectric BSTO plates was performed. The influence of transparent electrode deposition on properties of ferroelectric ceramic based on a solid solution of barium-strontium titanate was investigated. The measured low insertion loss of the Si-Ti-Ce thin-film deposited on BSTO ceramic substrate allows considering this material as the perspective for the transparent for microwaves electrodes realization.
