Antenna and wireless terminal device
View Patent ↗Embodiments of the present invention provide an antenna and a wireless terminal device. Through a first conductor connected to the inner side of an antenna body, the embodiments of the present invention can avoid the problem that in the prior art, while the antenna ensures the Specific Absorption Rate (SAR) performance of the wireless terminal device, the wireless performance of the wireless terminal device is greatly reduced. By adopting technical solutions of the present invention, while the SAR performance of the wireless terminal device is ensured, the wireless performance of the wireless terminal device cannot be affected.
