Abstract

The invention provides a dual-frequency antenna structure and an antenna system. The dual-frequency antenna structure comprises a dielectric plate, a metal ground, a first antenna branch knot and a second antenna branch knot, the dielectric plate has a front surface and a back surface, the metal ground and the first antenna branch knot are arranged on the front surface of the dielectric plate, and a feeding point is arranged between the metal ground and the first antenna branch knot; and the second antenna branch knot is arranged on the back surface of the dielectric plate, the dielectric plate is provided with a metal through hole electrically connected with the first antenna branch knot and the second antenna branch knot, and projections of the first antenna branch knot and the second antenna branch knot on the front surface of the dielectric plate have an overlapping area. According to the dual-frequency antenna structure provided by the invention, the equivalent capacitance values of the first antenna branch knot and the second antenna branch knot on the front and back surfaces of the dielectric plate are adjusted by adjusting the size of the overlapping region, the position of a resonant frequency point is flexibly adjusted by using the equivalent capacitance loading effect, and the antenna frequency point can be adjusted under the condition of not increasing the antenna branch knot and keeping the size of the antenna unchanged. unchanged.

Description

technical field [0001] The invention belongs to the technical field of antennas, and more specifically relates to a dual-frequency antenna structure and an antenna system. Background technique [0002] Dual-band antennas such as dual-band wifi antennas produce dual-band because they have two antenna stubs. Although the structure of two antenna stubs can achieve dual-band characteristics, it will inevitably increase the volume of the antenna. In antennas such as terminal antennas In the case of limited size, a larger antenna cannot be used in a compact device, which is not conducive to the high integration of the antenna. Contents of the invention [0003] The purpose of the present invention is to provide a dual-frequency antenna structure to solve the technical problem of the large volume of the dual-frequency antenna in the prior art. [0004] In order to achieve the above object, the technical solution adopted by the present invention is to provide a dual-frequency ant...
