UWB antenna and wearable device

Abstract

The invention discloses a UWB antenna and wearable equipment, which are applied to the field of signal transmission and are used for enhancing the signal transmission capability of the antenna, the UWB antenna comprises a dielectric substrate, a coaxial feeder line, a first radiation patch, a second radiation patch and a grounding patch, the first radiation patch and the second radiation patch are arranged on the front surface of the dielectric substrate, and the coaxial feeder line is arranged on the front surface of the dielectric substrate; the grounding patch is arranged on the back surface of the dielectric substrate, and the first radiation patch is connected with the grounding patch through a coaxial feeder line. According to the antenna, the second radiation patch is added on the basis of the first radiation patch, so that the radiation capability of the antenna can be enhanced, and furthermore, a certain gap is formed between the second radiation patch and the coaxial feeder line, so that the resonance current can be increased, and the bandwidth of the antenna is further increased. Furthermore, the grounding patch is provided with a plurality of hollow grooves, so that the current flowing path can be increased, and the working frequency band of the antenna can be widened and the signal transmission capability of the antenna can be improved under the combined action of the grounding patch, the first radiation patch and the second radiation patch.

Description

technical field [0001] The present application relates to the field of signal transmission, and in particular, to a UWB antenna and a wearable device. Background technique [0002] With the development of Internet of Things communication technology, higher and higher requirements are placed on the antenna as a communication component. For example, in order to improve the user's experience when using VR equipment, it is necessary to use an antenna with a wide bandwidth and multiple frequency bands. However, the antenna bandwidth and frequency bands in the existing technology are relatively narrow. The antenna of the frequency band is an urgent problem to be solved in the art. SUMMARY OF THE INVENTION [0003] The purpose of this application is to provide a UWB antenna and a wearable device, which can increase the resonant current, thereby increase the bandwidth of the antenna, widen the working frequency band of the antenna, and improve the ability of the antenna to transm...
