Problems solved by technology

The traditional metal waveguide structure has the advantages of high Q value, large power capacity, and low loss, but it has disadvantages such as large volume, difficult processing and debugging, and difficulty in integrating with the plane; the stripline structure is small in size and flexible in layout, but its open The coaxial structure introduces a large radiation loss in the millimeter wave frequency band, which is not suitable for millimeter wave band applications; the coaxial structure has a high Q value and a large power capacity, but in the millimeter wave frequency band, its size is too small, and the existing processing level is not easy to meet the demand. , and it is also difficult to integrate with planar circuits

Abstract

The invention discloses a millimeter wave dual-passband filter and a design method therefor. The millimeter wave dual-passband filter comprises a first PCB and a second PCB that are adhered to each other through a bonding layer, an SIW filter arranged on the first PCB and the second PCB, and a lower sideband filter arranged on the lower surface of the first PCB; the SIW filter comprises a copper coating layer arranged on the upper surface of the first PCB, a copper coating layer arranged on the lower surface of the second PCB, and a metal via hole and an inductive window that are formed in the copper coating layer on the upper surface of the first PCB and the copper coating layer on the lower surface of the second PCB and penetrating through the first PCB and the second PCB; and a blind hole for conducting the copper coating layer on the upper surface of the first PCB with the lower sideband filter is formed in the copper coating layer on the upper surface of the first PCB.

Description

technical field [0001] The invention belongs to the technical field of millimeter wave communication equipment, measuring instruments, etc., and in particular relates to a millimeter wave double-passband filter and a design method thereof. Background technique [0002] With the rapid development of communication technology and the exhaustion of spectrum resources in the microwave low frequency band, modern communication is developing towards the millimeter wave frequency band. The millimeter wave frequency band has the characteristics of relative bandwidth, short working wavelength, strong anti-interference ability, narrow beam, and good directivity. Wide relative bandwidth means large available bandwidth, high data transmission rate, and large channel capacity, while short and narrow working wavelength The characteristics of the beam width have high resolution in the application of target tracking and identification, and it has highlighted huge advantages in the fields of c...
