Abstract

The invention relates to a dual-frequency band antenna structure and a manufacturing method thereof. The dual-frequency band antenna structure comprises a first substrate unit, a second substrate unit, and an adhesion unit. The first substrate unit consists of a first insulating substrate, a first electrode layer and a first ground layer; the second substrate unit includes a second insulating substrate, a second electrode layer and a second ground layer, wherein a second dielectric coefficient is larger than a first dielectric coefficient; and a connecting pin unit includes a feed connecting pin successively penetrating the second substrate unit and the first substrate unit, wherein the feed connecting pin is insulated with the first electrode layer and the second electrode layer mutually and the first ground layer and the second ground layer are insulated with each other. The first substrate unit and the connecting pin unit cooperate with each other to form a first antenna with a first set working frequency band; and the second substrate unit and the connecting pin unit cooperate with each other to form a second antenna with a second set working frequency band, wherein the first set working frequency band is larger than the second set working frequency band.

Description

technical field [0001] The invention relates to an antenna structure and a manufacturing method thereof, in particular to a dual-band antenna structure and a manufacturing method thereof. Background technique [0002] With the development of communication technology, various electronic products using wireless communication technology have been born one after another, such as mobile phones, wireless Internet access devices, personal digital assistants and so on. Consumers' requirements for the performance, appearance design and size of these wireless communication devices are also increasing. Taking mobile phones as an example, the receiving frequency has developed from single-band and dual-band to triple-band and quad-band. The appearance of the mobile phone is streamlined and novel, and at the same time it has the characteristics of small size, light weight, and portability. Furthermore, due to the advancement of communication technology, an antenna with dual-frequency and...
