Problems solved by technology
However, the preparation of microwave devices into flexible microwave devices still faces many challenges. First, the widely used microwave ferrite materials are ceramic materials, which have high hardness and brittleness, and generally cannot be bent; second, the coplanar materials used in microwave devices Waveguides (CPW) are generally etched from printed circuit boards and are not flexible

Abstract
The invention provides a flexible microwave device and a preparation method thereof. The device includes a flexible waveguide and flexible ferrite films; the flexible ferrite films are formed on the upper surface of the flexible waveguide. The surface of the flexible waveguide is provided with two parallel S-shaped channels, the flexible ferrite films are located in the middles of the S-shaped channels, and one end of each S-shaped channel is externally connected with an electromagnetic wave generator. The flexible microwave device is simple in structure, small in size, low in cost and good inperformance, can be used for preparing flexible microwave signal processing devices such as isolators, circulators, phase shifters, diplexers, filters, microwave dielectric antennas and ferrite switches, and has important application prospects in microwave communication, the Internet of Things, intelligent household appliances and other fields.
Description
technical field [0001] The invention belongs to the technical field of microwave device preparation, and in particular relates to a flexible microwave device and a preparation method thereof. Background technique [0002] Modern microwave communication equipment is developing in the direction of miniaturization and portability. Microwave devices are made of ferrite materials with gyromagnetic properties as the key materials, and are mainly divided into: isolators, circulators, phase shifters, duplexers, filters, microwave dielectric antennas and ferrite switches, etc. . Compared with other materials, ferrite materials have excellent microwave properties such as greatly adjustable operating frequency, high dielectric constant, low insertion loss and near-zero temperature coefficient of resonance frequency, as well as good mechanical properties and chemical stability. , to ensure that high-power microwave and millimeter-wave loads can work normally in harsh environments. Th...
