Problems solved by technology

When the flip-type mobile phone is in the closed state, the ground area of ​​the flip-type mobile phone changes, and the circuit board located in the folded cover is closer to the main body. At this time, the radiation efficiency (Radiationefficiency) of this type of antenna will be greatly affected. In other words, when the flip phone is opened and closed, the performance of the antenna may not be stable enough

Abstract

The invention provides an antenna module, which comprises an antenna carrier and an antenna group; the antenna carrier comprises an upper surface and an outer end face adjacent to the upper surface; the antenna group comprises a first antenna and a second antenna; the length of the second antenna is greater than that of the first antenna; the outer end face comprises an upper edge adjacent to theupper surface and a lower edge far from the upper surface; the first antenna is arranged on the upper edge of the outer end face; the second antenna comprises a main body part, a bending part and a terminal part; the main body part is arranged on the lower edge of the outer end face; the bending part is extended from the main body part, and is arranged on the upper edge and the lower edge after extending from the lower edge to the upper edge; and the terminal part is extended from the bending part and arranged on the upper surface of the antenna carrier.

Description

technical field [0001] The present invention relates to an antenna module and a portable electronic device using the antenna module, in particular to a hidden antenna module for reducing the effect of frequency deviation and a portable electronic device using the hidden antenna module. Background technique [0002] As consumers increasingly demand thin, light and small mobile phones, the design of hidden antennas has become an important and difficult issue; in order to reduce the volume of mobile phones, the antenna needs to be properly configured so that it does not take up extra space and at the same time can Maintain a certain signal quality. [0003] At present, dual-band mobile phones include high-frequency antennas and low-frequency antennas. However, since many electronic components are generally arranged on circuit boards in mobile phones, this type of antenna is very easy to be emitted by these electronic components. Electromagnetic wave interference, therefore, in...
