Abstract: This disclosure provides an antenna and a wireless communication device that includes the antenna in which a high-order mode can be controlled while maintaining good radiation characteristics in both the fundamental mode and high-order mode. The antenna has a radiation electrode provided on a surface of a dielectric substrate and a branch electrode portion that branches from the radiation electrode portion at a branch point near the feeding port toward a vicinity of a position of the radiation electrode at which a maximum voltage of a high-order mode is generated.

Abstract: An antenna disposed on a substrate includes a radiating portion, a first coupling and feeding portion, and a second coupling and feeding portion. A length of the radiating portion is substantially equal to a half wavelength of electromagnetic signals radiated by the radiating portion. Each coupling and feeding portion includes a feeding part and a coupling part. The feeding part feeds the electromagnetic signals to the radiating portion via the coupling part so as to achieve effects of a multiple-input multiple-output (MIMO) antenna.
