Further, the insulator and the coaxial axle center of air are on same vertical line.
Further, SIW shielding ground hole is provided with two rows, is located at the opposite side of the substrate upper surface.
Further, the insulator is 50 ohm coaxial insulators.
Compared with prior art, the utility model has the following beneficial effects:
(1) the utility model coaxially will directly switch to substrate integration wave-guide, be not required to solve traditional by microstrip transitions
The problem of SIW is gradually gradient to by microstrip line coaxially is needed to SIW transition, so that the transition structure has structure simply easy
Row；By one section of air coaxial transition, it is connected to substrate surface layer transition member via contact pin, is finally directly connected to table on SIW
The ground of layer, which achieves that, coaxially turns substrate integration wave-guide, and insertion damage small with easy to operate, transition structure occupied space size
Consume feature small, that standing wave is small.
(2) transition member of the utility model and air coaxially play the role of impedance matching, guarantee signals transmission
