Title: ANTENNA AND MOBILE TERMINAL
Abstract:
An antenna and a mobile terminal, relating to the technical field of antennae, and achieving design within a small space of an antenna having multiple resonant frequencies. The antenna comprises a first radiator (2) and a first capacitor structure (3). A first end (21) of the first radiator (2) is electrically connected to a signal feed end (11) of a printed circuit board (1) via the first capacitor structure (3). A second end (22) of the first radiator (2) is electrically connected to a ground end (12) of the printed circuit board (1). The first radiator (2), the first capacitor structure (3), the signal feed end (11) and the ground end (12) form a first antenna, used to generate a first resonant frequency. The electrical length of the first radiator (2) is greater than an eighth of a wavelength corresponding to the first resonant frequency, and the electrical length of the first radiator (2) is less than a quarter of the wavelength corresponding to the first resonant frequency.
