A kind of radar antenna test fixture, including the transverse slat intersecting and being fixedly connected perpendicular to one another and riser, first antenna installing hole is offered on described transverse slat, offer the second antenna installing hole on riser, and the centrage in first antenna installing hole is equal with the centrage in the distance between riser plate face and the second antenna installing hole and the distance between transverse slat plate face.
Preferably, described transverse slat is set to the double-layer plate face structure being made up of upper cross plate and lower cross plate, and described first antenna installing hole is opened on upper cross plate, the plate face of described lower cross plate offers for testboard installing hole joining with testboard.
It is further preferred that be provided with several reinforcing plates between described upper cross plate and riser and between lower cross plate and riser.
Further, described reinforcing plate is set to four, and described in two of which, reinforcing plate is between upper cross plate and riser, and two other described reinforcing plate is between the region that upper cross plate, lower cross plate, riser surround.
It is further preferred that be provided with the through hole for cabling on described upper cross plate, lower cross plate and riser.
Further, a diameter of the 100～200mm of described through hole.
The beneficial effects of the utility model are:
1) this utility model uses the transverse slat and the version of riser intersecting vertically and being fixedly connected, when real work, transverse slat of the present utility model being fixed on testboard, if needing antenna is carried out the test of vertical orientations, then antenna being vertically fixed on transverse slat；If needing antenna is carried out the test of level orientation, then antenna is fixed in portrait in the horizontal direction.Thus, this utility model not only simple in construction, and also easy for installation when testing, cabling is easy, it is possible to meet antenna in vertical orientations and the test of level orientation simultaneously.
2) centrage of the antenna installing hole being positioned on described upper cross plate is equal to the distance of described upper cross plate with the centrage of the antenna installing hole on described riser to the distance of described riser, ensure that this test fixture is when carrying out level orientation and vertical orientations test, the central point of antenna element is in the same space point position, and therefore this utility model is effective to ensure that measuring accuracy.
3) transverse slat in this utility model is set to the double-layer plate face structure being made up of upper cross plate and lower cross plate.It practice, the transverse slat in this utility model can be designed as the multilamellar board face structure of at least two-layer.Transverse slat structure in this utility model is preferably double-layer plate face structure, not only simple in construction, it is easy to manufacture, and on the one hand can be effectively reduced height of C.G., guarantee this test fixture stability when following testboard and rotating, on the other hand the most then can be fixed with testboard by the testboard installing hole on lower cross plate and couple, facilitate fixing, be also effectively improved test fixture and testboard couples tightness.
4) several reinforcing plates it are provided with between the upper cross plate in this utility model and riser and between lower cross plate and riser, thus ensure that the tightness coupled between riser with upper horizontal slope and riser with lower horizontal slope, improve structural strength and the overall performance of this test fixture.
