ABSTRACT:
Methods and apparatus for testing wireless devices. Devices being tested receive and transmit radio frequency test signals. These radio frequency test signals are received or transmitted using an antenna associated with the device, and then are transmitted or received using a unique wide-band tapered-slot antenna connected to a test system. The wide-band tapered-slot antenna has an input path that is substantially orthogonal to the tapered slot, and one of the conductors defining the slot is grounded.
