When defeated signal, transmission line 110 is needed transmission line 110 carrying out shielding protection by extraneous interference in order to prevent,
In, the present invention uses a shielding element 20, and shielding element 20 is set on calibration network component 10, transmission line 110 relative to
The internal signal in 20 place space of shielding element is isolated with the external world, meanwhile, shielding element 20 is used for will be where transmission line 110
Space is divided into a plurality of cavities, and shielding element 20 is covered on transmission line 110, and transmission line 110 is coated on shielding
In element 20, since there are the presence of calibration network route and feeding network, the feeding network meetings of inside cavity on transmission line
The electromagnetic energy for having motivated different mode generates resonance in required frequency passband, and the power of feeding network, phase is caused to occur
Unusual fluctuations, and the cavity that resonance is also required to certain space size is generated, therefore, compared to the calibration net of traditional full page structure
110 place space of transmission line is divided into a plurality of cavities using shielding element 20 by network device 200, the present invention, one big
Cavity is divided into several lesser cavitys, the quasi- co-planar waveguide that is formed between calibration network component 10 and shielding element 20 or
On the quasi- microstrip transmission lines road 110 of person, 110 region of transmission line is separated into multiple small cavitys by shielding element 20, should
