Abstract: An antenna apparatus includes a plurality of patch antenna patterns, a plurality of first feed vias each electrically connected to a corresponding patch antenna pattern among the plurality of patch antenna patterns, and a plurality of first feed lines each electrically connected to a corresponding first feed via among the plurality of first feed vias. Each of the first feed vias is electrically connected to the corresponding patch antenna pattern at a point offset from a center of the corresponding patch antenna pattern in a first direction. An angle between a direction in which each of at least one of the plurality of first feed lines starts to extend from the corresponding first feed via and a direction in which each of remaining ones of the plurality of first feed lines starts to extend from the corresponding first feed via is not zero degrees and is not 180 degrees.

Abstract: There is provided a circuit board capable of internally transferring a signal through radio communications. The circuit board according to the present disclosure may include: an insulation layer; a first signal transfer circuit formed of a circuit pattern on one surface of the insulation layer; and a second signal transfer circuit formed of a circuit pattern on the other surface of the insulation layer and wirelessly transferring a signal through resonance with the first signal transfer circuit; wherein the first and second signal transfer circuits transfer the signal in a super high frequency (SHF) band or an extremely high frequency (EHF) band.

Abstract: Disclosed herein is a multiple-input multiple-output (MIMO) wireless communication apparatus including: a plurality of radio frequency (RF) modules each processing RF signals input; a plurality of local area communication modules processing a local area communication signal input; a plurality of switches; and a control block determining whether there is an idle RF module in the plurality of RF modules at the time of the MIMO mode operation and switching a corresponding switch so that the local area communication module operating in the MIMO mode and a corresponding RF antenna corresponding to the idle RF module are connected to each other. Therefore, the MIMO mode is implemented without adding the local area communication dedicated antenna, thereby making it possible to maximize space utilization and reduce a cost.
