1. An antenna subsystem with improved radiation performances, comprising:
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; wherein:
the AiM comprises a base, and one or more radiators;
the one or more radiators are conductive;
the antenna subsystem provides a spherical coverage by a combination of a first component of gain and a second component of gain; and
the auxiliary structure is insulated from the one or more radiators, and is 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;
the one or more radiators are placed on a front surface of the base, and distribute along an array direction;
the front surface of the base is perpendicular to a forward direction;
the auxiliary structure comprises an upper front structure;
on a geometric plane perpendicular to the array direction, a position of the upper front structure is away from a position of the one or more radiators along an upward-forward direction, and
the upper front structure is arranged to direct the radiation pattern of the first component of gain to another upward-forward direction, or to reflect the radiation pattern of the first component of gain to a downward-forward direction.
