ANTENNA DEVICE

摘要

The embodiments of the present invention disclose an antenna device. An embodiment of the present invention includes: a metal panel and a dipole antenna, wherein the metal panel is provided with a resonant slot thereon; the resonant slot has a resonant frequency that matches an operating frequency of the dipole antenna; and a direction of polarization of the resonant slot is at a preset angle to a direction of polarization of the dipole antenna. The embodiment adds a resonant slot onto the metal panel, which can effectively solve the reflection effect of the metal panel, and thus increase the bandwidth and radiation efficiency of the dipole antenna.
