Abstract: According to some embodiments, a system is provided for simulating a cluster of reflections. The system includes an array of antenna elements distributed in space over a solid angle having an angular spread. The solid angle is substantially less than a full sphere and each antenna element has a spatial orientation. The system also includes a variable path simulator connected to the antenna elements and configured to apply one of excitations to the antenna elements and weights to signals from the antenna elements. The variable path simulator enables simulation of a near field arising from a cluster of reflections of a multipath environment.

Abstract: A method and system for measurement of a device under test (DUT) are provided. According to one aspect, a system includes a first positioner having a first antenna and a second positioner having a second antenna. The system also includes circuitry configured to cause the first antenna to radiate a test signal to the DUT and to implement one of a probing mode and an interference mode. The probing mode causes, for each of at least one position of the first antenna, the second antenna to receive a signal from the DUT at each of the second set of positions of the second antenna. The interfering mode causes, for each of at least one position of the first antenna, the second antenna to transmit an interfering signal to the DUT at each of the second set of positions of the second antenna.

The system also includes a spatial environment simulator connected to the antenna elements and configured to apply one of excitations to the antenna elements and weights to signals from the antenna elements. The combination of the spatial distribution of the antenna elements, the orientation of the antenna elements, and the weighting applied by the variable path simulator simulates a near field arising from a cluster of reflections of a multipath environment.

Abstract: Embodiments include systems and methods for simulating a multipath environment for testing a device. In one embodiment, a plurality of antennas are placed around a device under test in an anechoic chamber. Each of a plurality of the antennas is connected to a path of a variable path simulator capable of generating multiple paths between the antennas and external wireless communication test equipment. The variable path simulator introduces a delay spread into each path. In this way, a multipath environment is simulated with signals appearing to arrive from different angles and different distances. Each of a plurality of antennas may be adapted to produce substantially plane waves at the device under test.
