Problems solved by technology

At the same time, due to the change of body position when people exercise, the environment they live in and other factors will affect the propagation of signals, so it is difficult for an antenna with a single radiation direction to meet the requirements of communication.

Abstract

The invention discloses a reconfigurable wearable microstrip antenna. The antenna comprises a dielectric substrate a; a dielectric substrate b is arranged below the dielectric substrate a; a metal floor is arranged between the dielectric substrate a and the dielectric substrate b; an antenna radiation unit is arranged on the upper surface of the dielectric substrate a; a feed network is arranged on the lower surface of the dielectric substrate b; the feed network is connected with the antenna radiation unit through a copper shaft; the feed network is divided into four feed branches by a feederline through three equal power dividers; each feed branch is provided with an output port which is connected with the copper shaft; and a diode a and a diode b are arranged on each of the two feed branches at the upper end of the feed network. The rotary placement of an antenna unit and different substrate thicknesses are more beneficial to the formation of an omnidirectional radiation mode; andthe antenna feed network realizes the phase changes of the ports by changing the on-off states of the diodes, so that the antenna can realize the switching of different radiation modes.

Description

technical field [0001] The invention belongs to the technical field of antennas, in particular to a reconfigurable wearable microstrip antenna. Background technique [0002] Wearable antenna (Wearable Antenna) refers to the use of special methods or special materials to integrate the antenna on the carrier that the human body often wears. [0003] Wearable antennas have great application value in medical, military and other fields. In terms of medical care, antennas, sensors and medical equipment can be placed on the human body together, and the detected data can be transmitted to the network terminal through the antenna, so that doctors can monitor the patient's physical status in real time, which is very worthwhile for the elderly's medical care services expected. In the military field, compared with traditional head-mounted antennas, wearable antennas will be widely used due to their small size, portability and concealment. [0004] Since the working environment of the...
