Abstract: The invention provides an antenna subsystem with improved radiation performances. The antenna subsystem may comprise an antenna-in-module (AiM), an auxiliary structure being conductive, and a support structure being nonconductive and disposed between the AiM and the auxiliary structure. The AiM may comprise a base, and one or more radiators being conductive. The antenna subsystem may provide a spherical coverage by a combination of a first component of gain and a second component of gain. The auxiliary structure may be insulated from the one or more radiators, and may be configured for orienting a radiation pattern of the first component of gain and a radiation pattern of the second component of gain to two different directions respectively; and/or, causing the spherical coverage provided by the antenna subsystem to be broader than a spherical coverage provided by the AiM alone.

Abstract: A method for evaluating radio performance of a device under test (DUT) comprises the following steps. A first set of points, a second set of points and a third set of points are defined to locate on a sphere surrounding the DUT. A signal power of the DUT is evaluated at the first set of points to identify a first region related to the first set of points. Candidates of the second set of points are selected based on the first region. The signal power of the DUT is evaluated at the candidates of the second set of points to identify a second region related to the second set of points. Candidates of the third set of points are selected based on the second region. The signal power of the DUT is evaluated at the candidates of the third set of points to identify a beam peak.
