Abstract

The invention discloses a high efficient microwave energy receiving board formed by secondary wavelength resonance structural units. Each of the unit is in a square structure. A layer of square sheet copper is plated in the middle of a Rogers circuit board of an intermediate layer; the sheet copper is formed by two right-angle isosceles triangles. Two sides of a slit between the two right-angle isosceles triangles are respectively connected with two input interfaces of a high frequency rectification chip and are used as input terminals of a high frequency rectification circuit; and four sides of the square sheet copper are respectively connected with their own long-strip sheet coppers respectively through strip-shaped sheet coppers. A layer of sheet base plate is fully plated under the circuit board of the intermediate layer; two crossed annular openings are opened in the middle of the sheet base plate; two small sheet coppers in the middle of the two annular openings pass through through holes of the circuit board and are respectively connected with two output terminals of the high frequency rectification chip; and a high frequency filtering capacitor is in parallel connection between the two sheet coppers. According to the invention, super high efficient receiving and conversion of microwave energy can be realized; the costs are low and the structure is simple; and efficiencies of receiving and conversion of energy are high; and therefore, the high efficient microwave energy receiving board can be widely applied to microwave energy transmission of various frequency ranges as well as research and development and application fields of receiving equipment.

Description

technical field

[0001] The invention relates to a microwave energy receiving board, in particular to a high-efficiency microwave energy receiving board composed of sub-wavelength resonant structural units. Background technique

[0002] Microwave energy transmission technology refers to a non-contact energy transmission technology that uses free space as the propagation medium to directly transmit energy from the transmitting end to the receiving end. Since the transmission efficiency of microwave energy transmission technology in the S and C bands is generally above 90%, Moreover, the intensity and direction of microwave beams are easier to control, making microwave energy transmission technology receive more and more attention internationally and domestically. Especially in recent years, it has been fully developed. There are broad application prospects.
