Abstract:
According to embodiments of the present application, provided are an antenna and an electronic device. The antenna comprises: a first radiator; a transmission line provided with a first end and a second end, the first end being coupled to the vicinity of a ground end or an open end of the first radiator, and the length T of the transmission line being set to T=1/4λ or T=1/2λ, wherein λ is a medium wavelength corresponding to one of resonances generated when the antenna is fed; and a feed unit coupled to a coupling point of the transmission line and feeding the first radiator via the transmission line. By providing the transmission line having a predetermined length, when a boundary condition is satisfied, a transmission line mode and a radiator mode can be superimposed, thereby improving the efficiency and bandwidth of the antenna.
