Personal robot

An electronic device is provided. The electronic device includes a housing, a wireless communication circuit, a first antenna radiator electrically connected with a first ground, a second antenna radiator electrically connected with a second ground, a feeding unit that feeds at least one of the first antenna radiator or the second antenna radiator, and a first switch that operates at a first connection state where the feeding unit and the first antenna radiator are electrically connected to each other, at a second connection state where the feeding unit and the second antenna are electrically connected to each other, or at a third connection state where the feeding unit and the first antenna radiator are connected to each other and the feeding unit and the second antenna radiator are electrically connected to each other, based on a first control signal from the wireless communication circuit.

Electronic device comprising antenna

A multi-band antenna apparatus using a multiple frequency band is provided. The apparatus includes a substrate body formed in a flat plate structure having a preset thickness and in which at least one dielectric plate is stacked, a power supply line, disposed at the substrate body and connected to an external power source, for forming an electromagnetic field when power is supplied from the external power source, a radiation line, separated from the power supply line using the dielectric plate as the boundary in the substrate body, for forming an overlapping area overlapped with the power supply line along one axis through at least a portion, and for resonating in a frequency band determined according to the overlapping area when the electromagnetic field is formed, and a ground plate disposed in at least one an upper ground area and a lower ground area of the substrate body, for grounding the radiation line by contacting with the radiation line.
