Abstract

A device for Over-the-Air testing includes a carrier unit, an automatic positioning member and a housing unit. The automatic positioning member is adapted to convey an object under test to an electrical connection zone of the carrier. The housing unit includes a housing shell, a pressing plate and a receiver. The housing shell defines a testing space that has an open end where the pressing plate is disposed. The housing unit and the carrier unit are movable relative to each other. When the carrier unit abuts the housing unit, the object under test is exposed to the testing space and is pressed against the electrical connection zone by the pressing plate so that electromagnetic waves from the object under test are received by the receiver.

First claim

What is claimed is:

1 . A device for Over-the-Air testing comprising:
a carrier unit including a holding base that has an electrical connection zone; an automatic positioning member operable to convey an object under test to said electrical connection zone; and a housing unit including a housing shell, a pressing plate and a receiver, said housing shell having a testing space and an open end, said pressing plate being disposed at said open end, said receiver being disposed on said housing shell inside said testing space; wherein said open end of said housing shell of said housing unit is spaced apart from said carrier unit and faces said carrier unit, said housing unit and said carrier unit being movable relative to each other; wherein, when said pressing plate of said housing unit and said holding base of said carrier unit abut against each other to close said open end, the object under test is exposed to said testing space and is pressed against said electrical connection zone by said pressing plate, whereby electromagnetic waves emitted by the object under test are receivable by said receiver of said housing unit.

2 . The device for Over-the-Air testing as claimed in claim 1 , wherein said carrier unit further includes a lifting platform, said holding base of said carrier unit being disposed on said lifting platform, said lifting platform being operable to carry said holding base to move toward said housing unit so that said holding base abuts against said pressing plate of said housing unit.

3 . The device for Over-the-Air testing as claimed in claim 2 , wherein said housing shell has a surrounding wall extending around said testing space, and an end wall connecting one end of said surrounding wall and bounding one side of said testing space, said open end of said housing shell being situated at another end of said surrounding wall opposite to said end wall, said pressing plate being removably attached to said open end of said surrounding wall, said holding base being removably attached to said lifting platform.

4 . The device for Over-the-Air testing as claimed in claim 3 , wherein said pressing plate spans said open end of said housing shell, and has a through hole, an inner periphery surrounding said through hole, and an outer periphery surrounding said inner periphery, said outer periphery being removably attached to said open end of said housing shell, said electrical connection zone of said holding base being registered with said through hole when said holding base abuts against said pressing plate so that the object under test is exposed to said testing space through said through hole.

5 . The device for Over-the-Air testing as claimed in claim 1 , wherein said housing unit further includes an electromagnetic wave absorber, said housing shell of said housing unit having an inner surface inside said testing space of said housing shell, said electromagnetic wave absorber being disposed on said inner surface.

6 . The device for Over-the-Air testing as claimed in claim 1 , wherein said housing shell ( 31 ) of said housing unit has an inner surface inside said testing space of said housing shell, said receiver of said housing unit being disposed on said inner surface.

7 . The device for Over-the-Air testing as claimed in claim 1 , wherein said carrier unit further includes a circuit member disposed on said electrical connection zone of said holding base of said supporting unit, the object under test being electronically connected to said circuit member when the object under test is positioned at said electrical connection zone.

8 . The device for Over-the-Air testing as claimed in claim 7 , wherein said carrier unit further includes a connecting jig disposed over said circuit member of said carrier unit for holding the object under test on top of said circuit member.

9 . The device for Over-the-Air testing as claimed in claim 8 , wherein said holding base of said carrier unit has a concave part formed in a surface thereof that faces said housing unit so as to serve as said electrical connection zone of said holding base, said circuit member and said connecting jig of said carrier unit being disposed in said concave part, said circuit member having a plurality of probes that protrude through said connecting jig, the object under test being electronically connected to said probes when the object under test is held by said connecting jig on top of said circuit member.

10 . The device for Over-the-Air testing as claimed in claim 1 , wherein said holding base of said carrier unit and said pressing plate of said housing unit are made of non-metal materials.

11 . The device for Over-the-Air testing as claimed in claim 1 , wherein said automatic positioning member is a mechanical arm.
