Abstract

The invention discloses a dual-frequency dipole antenna, which includes a substrate, a grounding area, a radiation body, a grounding point and a feeding point. The ground area can be disposed on the substrate. The radiating body can be adjacent to the grounding area, can be arranged on the substrate, and can include a first radiating body and a second radiating body, the first radiating body can be connected to the second radiating body, and the first radiating body and the second radiating body can There may be a groove between the bodies, and the size of the radiation body may be asymmetric to the size of the grounding area. The grounding point can be arranged on the substrate and can be connected to the grounding area. The feed-in point can be arranged on the substrate and can be connected to the radiation body, and the ground point and the feed-in point can be arranged adjacent to each other.

Description

technical field [0001] The invention relates to a dual-frequency dipole antenna, in particular to a dual-frequency dipole printed antenna with simple structure, low cost and easy adjustment of operating frequency band. Background technique [0002] With the advancement of science and technology, handheld electronic devices have become an indispensable equipment in people's lives. In order to cope with the massive use of handheld electronic In light and handy handheld electronic devices (such as mobile phones, notebook computers, etc.) or wireless transmission devices (such as wireless sharers, wireless network cards, etc.). For example, a planar inverted-F antenna (Planar Inverse-F Antenna, PIFA), monopole antenna (Monopole Antenna) or dipole antenna ( Dipole Antenna) has been widely used in various handheld electronic devices. [0003] However, prior art antennas suffer from a number of grievous disadvantages. For example, the bandwidth of the antenna in the prior art is...
