Abstract

The invention provides an annular circularly-polarized implantable microstrip antenna used for a wireless body area network. The annular circularly-polarized implantable microstrip antenna comprises aradiation patch and a dielectric substrate, wherein the radiation patch is arranged on a front surface of the dielectric substrate and comprises an annular microstrip piece and a round metal piece, the round metal piece is arranged in the center of the annular microstrip piece, a pair of disturbance components are arranged on an inner boundary of the annular microstrip piece, a plurality of firstgrooves and a plurality of second grooves are formed in the annular microstrip piece, and a third groove is formed in the round metal piece. The annular circularly-polarized implantable microstrip antenna has a small antenna size and has an external profile suitably implanted in a human body, and data receiving and sending in the wireless body area network are more facilitated due to characteristic of circular polarization.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a miniaturized annular circularly polarized implantable microstrip antenna suitable for use in a wireless body area network. Background technique [0002] Wireless Body Area Network (WBAN) is a communication network that is centered on the human body and consists of sensors on the human body or even in the body and various network elements around the human body. It is the core technology of the health monitoring system. Its sensors distributed on the body can effectively perceive one or more human physiological signals, process and store them and send these signals to an external WBAN server, and finally transmit them to the medical server for analysis and diagnosis by professionals. One of the main problems faced by this technology is that the human body is a non-homogeneous medium, and the communication between the implanted device in the human body and the external b...
