Abstract

The invention discloses a monopole antenna based on flexible wearable application. The monopole antenna comprises a grounding plate, a dielectric substrate, a feeding network and a radiating patch, wherein the thickness of the dielectric substrate is 1.6 millimeters, the grounding plate is arranged at one side of the dielectric substrate, the feeding network and the radiating patch are arranged at the other side of the dielectric substrate, a groove is formed in an upper part of the radiating patch, convex blocks are symmetrically and integrally arranged at a left side and a right side of the groove, a trapezoid structures is symmetrically arranged at a left side and a right side of the radiating patch, and the width of the grounding plate is equal to the width of the dielectric substrate. The antenna has favorable characteristics of radiating gain and radiating direction in a frequency band of 3.1-7.2GHz, and signal radiation still can be effectively performed in a relatively severe deformation condition. The antenna is small in size and simple in structure, is easy to fabricate, is suitable for a wireless communication system and device, is a study hotspot of the recent fields of electromagnet and a wearable device, and has great development prospect.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to a monopole antenna based on flexible and wearable applications. Background technique [0002] With the rapid development of wireless network technology, body-centered network has become an important part of the fifth-generation mobile communication, and one of its important research directions is the study of flexible wearable antennas.
