Problems solved by technology

Two adjacent SIW cavities can achieve a dual-mode dual-band filter through window magnetic coupling, but the two passband bandwidths cannot be independently controlled
In order to further reduce the size of the SIW dual-band filter, everyone tends to design the HMSIW dual-band filter, or use a multi-layer board method, but how to control the independent control of the passband bandwidth of the HMSIW dual-band filter is still a problem

Embodiment Construction

[0027] The present invention will be further described below in conjunction with accompanying drawing

[0028] Such as figure 1 , 2 As shown, the inventive HMSIW dual-band filter is formed by superimposing two layers of PCB boards. The lower dielectric board 14 is provided with a number of periodically distributed second metal columns 15 penetrating through the dielectric board. These metal columns form a "匚" structure; the upper layer The dielectric plate 13 is provided with a number of periodically distributed first metal pillars 1 that run through the dielectric plate. The structure surrounded by these metal pillars is the structure after the second metal pillar enclosing structure has been turned horizontally, with the same size and size; and it is in a "匚" structure The two arms of several first metal pillars 1 after being turned horizontally coincide with the two arms of several second metal pillars 15 in a "匚" structure, and the first metal pillars 1 and the second met...

Abstract

The invention relates to an HMSIW (half mode substrate integrated waveguide) dual-mode dual-band filter capable of independently controlling bandwidths. The dual-band filter is formed by using a double-layer HMSIW cavity staggered folding manner and a vertical coupling manner; TE101 and TE201 modes of HMSIW cavities work simultaneously, the TE101 modes of the two cavities constitute a first pass band and the TE201 modes of the two cavities constitute a second pass band; a middle layer comprises 6 coupling grooves and the coupling intensity of the two pass bands can be controlled by changing the size of the coupling grooves; input and output feeders are loaded on an upper metal surface and a lower metal surface respectively. The requirement of a modern multi-standard radio frequency systemfor miniaturization is met by introducing HMSIW dual mode work and using a double layer plate overlaying manner, and the problems of large size and complex design of traditional dual-band filters aresolved.

Description

technical field [0001] The invention belongs to the technical field of electronic information, and specifically relates to a double-layer half-mode substrate integrated waveguide (HMSIW) dual-mode dual-band filter, which is a HMSIW dual-band radio frequency filter with independently controllable bandwidth and miniaturization. Background technique [0002] With the rapid development of wireless communication, there is an increasing demand for dual-band and multi-band filters, which are required to have the characteristics of small size, low loss, high frequency selectivity, and high flexibility. The emerging substrate-integrated waveguide (SIW) technology, due to the advantages of low cost, low profile, relatively high Q, high power handling capability, and high-density integration, represents a very promising candidate for modern wireless communication systems for microwave and millimeter Wave Apps provides an attractive platform. [0003] In the past few years, research an...
