Abstract

The invention provides electronic equipment, and relates to the technical field of antennas. The electronic equipment comprises a composite antenna composed of a slot antenna and a line antenna. Wherein a first strip-shaped conductor of the slot antenna comprises a first grounding part, a second grounding part and a feed part, and the first grounding part and the second grounding part are respectively two end parts of the first strip-shaped conductor. The feed part is located between the first grounding part and the second grounding part. A second strip-shaped conductor of the line antenna includes a first end portion and a second end portion. The first end portion of the second strip-shaped conductor is electrically connected to the first grounding part. And the second end part of the second strip-shaped conductor is an open end. The composite antenna formed by the slot antenna and the line antenna can generate a plurality of resonant modes to realize broadband coverage, and can also ensure that the plurality of resonant modes meet the requirement of low SAR value to reduce the influence of electromagnetic wave radiation on a human body.

Description

technical field [0001] The present application relates to the technical field of antennas, in particular to an electronic device. Background technique [0002] With the rapid development of key technologies such as full screens, thinner and lighter electronic devices and extreme screen-to-body ratios have become a trend. This design greatly reduces the space for antenna layout. In such an environment where antennas are tightly arranged, it is difficult for traditional antennas to meet the performance requirements of multiple communication frequency bands. In addition, in the design of mobile phone antennas, attention should also be paid to the impact of electromagnetic wave radiation on the human body. The energy absorbed by the electromagnetic wave by the human body is quantified by the electromagnetic wave specific absorption ratio (Specific Absorption Ratio, SAR). A small SAR value represents a small effect of electromagnetic radiation on the human body. Therefore, how...
