Abstract

The invention relates to a dipole antenna, which comprises a substrate, a radiating part and a grounding part. The radiating part is arranged on the substrate; the outer frame of the radiating part is similarly D-shaped; at least one slot is formed in the radiating part; the grounding part is also arranged on the substrate; and at least one slot is formed in the grounding part. Moreover, the allocation positions of a feed-in point and a grounding point of the antenna are not limited by the center positions of the sides of the radiating part and the grounding part.

Description

technical field [0001] The present invention relates to an antenna, and in particular to a D-type dipole antenna. Background technique [0002] In today's era of rapid technological development, various sizes of lightweight antennas have been developed to be used in various sizes of increasingly lightweight handheld electronic devices (such as mobile phones or notebook computers) or wireless transmission devices (such as APs) middle. For example, a dipole antenna with a light structure, good transmission performance, and can be easily installed on the inner wall of a handheld electronic device has been applied in wireless transmission or wireless communication devices of various handheld electronic devices. [0003] However, due to the design style of the traditional dipole antenna, it is not easy to change its oscillation frequency, nor is it easy to increase its bandwidth. Moreover, the size of the traditional dipole antenna is not easy to reduce, the low-frequency chara...
