Abstract
A wireless communication device is presented. The wireless communication device includes: a high-frequency circuit; and an analog signal processing circuit that performs gain adjustment such that a gain for each of the plurality of antenna elements, in case of a signal transmission or in case of a signal reception, is a predetermined value being dependent on a position of the antenna element. The analog signal processing circuit includes a first splitter/combiner between the high-frequency circuit and the plurality of antenna elements. For each antenna element in the plurality of antenna elements, a second splitter/combiner is coupled to a particular antenna element in the plurality of antenna elements and, for each antenna element in the plurality of antenna elements, two or more phase shifters of a given M system are connected in parallel with each other and coupled between the first splitter/combiner and a corresponding second splitter/combiner.
