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.

Abstract: The present invention provides an antenna system for a user equipment (UE). The antenna system may include a housing of the UE and a radiated module including a first quantity of radiators. The housing may include a second quantity of openings. The radiated module may be arranged to excite the housing for wireless signaling at a target band; at the target band, a performance of the antenna system may be better than a performance of the radiated module alone without the housing.

Abstract: A communication device includes an antenna, a frequency dividing circuit, and at least one variable impedance circuit. The frequency dividing circuit has a common port coupled to the antenna and at least one output port. The frequency dividing circuit is configured to divide a frequency range received from the common port into a plurality of frequency sub-ranges and output at least one of the frequency sub-ranges respectively at the output port. Each variable impedance circuit is coupled between a corresponding output port of the frequency dividing circuit and a first reference voltage. Each variable impedance circuit provides a respective variable impedance value switched between different respective impedance values.
