Abstract

The invention discloses a multimode broadband antenna module and a wireless terminal, which belong to the field of wireless communication. The multimode broadband antenna module not only has a large-range work broadband, but also has quite a small size. The multimode broadband antenna module comprises a printing circuit board and an antenna body. The antenna body comprises a first radiation body and a second radiation body, which are electrically connected to the printing circuit board. The first radiation body comprises a connecting part, a low-frequency part and a high-frequency part. The second radiation body comprises a grounding part, a low-frequency part and a high-frequency part. A first preset distance is disposed between the low-frequency part of the first radiation body and the low-frequency part of the second radiation body. A second preset distance is disposed between the high-frequency part of the first radiation body and the high-frequency part of the second radiation body. Accordingly, a coupling capacitance effect can be formed between the first radiation body and the second radiation body.

Description

technical field [0001] The invention relates to the field of radio communication, in particular to a multi-mode broadband antenna module and a wireless terminal. Background technique [0002] An antenna is a device used in radio equipment to transmit or receive electromagnetic wave signals. In recent years, the design and performance of mobile terminal antennas for wireless communication have more and more influence on the development direction of mobile communication, among which, the influence on wireless terminals such as mobile phones, PDAs (Personal Digital Assistance), and MP3 / MP4 is particularly large. The bandwidth characteristics of the antenna design have a significant impact on the radiation characteristics. Antennas achieve signal propagation and energy radiation based on frequency resonance. If an antenna can resonate at multiple frequencies, the antenna will work at multiple frequencies. On the other hand, if there are multiple resonant frequencies in the an...
