Through-hole both ends are connect with bottom metal layer and top layer metallic layer respectively.
Further, a conduit, medium base two sides are had among the side wall of two sides inside the metal shell
It is in conduit and fixed along being fastened on.
Further, the plated-through hole is arranged among medium base in two rows of.
Further, one row of plated-through hole is arranged along a side of bottom metal layer and top layer metallic layer edge, i.e.,
The center of circle of plated-through hole is located on the edge line of bottom metal layer and top layer metallic layer, and another row of plated-through hole is along bottom gold
Belong to the other side edge setting of layer and top layer metallic layer.
Further, the equal spaced set of the every row of the plated-through hole, the spacing between adjacent metal through-hole are little
In the quarter-wave of center frequency point.
Further, the plated-through hole two rows are symmetrical set in medium base.
Further, described plated-through hole two rows or so are arranged in a staggered manner in medium base, a metal of first row
Change through-hole to be located on the perpendicular bisector of two adjacent metal through hole center lines of second row.
Further, the medium base uses 5880 plate of Roges, bottom metal layer, top layer metallic layer, metallization
Through-hole is all made of copper product.
Compared with prior art, the present invention having the following advantages that and effect: opposed configuration of the present invention is simple, and cost is relatively low,
Convenient for circuit design and debugging, processing and assembly are more easier, L-band and S-band have good electromagnetic transmission characteristic and
Lower circuit loss.Solve high requirement on machining accuracy in traditional scheme and literature protocol, higher cost or structure ratio
More complex problem.
