Abstract

The invention discloses a method for improving the performance of an electrically small antenna for a human body center wireless communication network and a formed electrically small antenna structure. A certain space around the electrically small antenna is filled with a filling material with a high dielectric constant and low conductivity, and the electrically small antenna is surrounded and sealed, so that the effects of improving the transmission efficiency, expanding the working bandwidth and reducing the transmission loss of the electrically small antenna are achieved. A wave-transparentmaterial is used as a packaging shell in the periphery of the filling space, so that the effects of fixing the electrically small antenna and the filling material are achieved. Electronic sensing equipment is arranged in a central area in the shell; an interlayer space between the electronic sensing equipment and the shell is a space which continuously wraps the periphery of the electronic sensing equipment; thus, under the limited size, the electronic sensing equipment and the electrically small antenna are integrated, the space occupied by the filling material is increased to the maximum extent, and therefore the radiation efficiency and the receiving efficiency of the electrically small antenna are improved to the maximum extent, the working bandwidth is expanded, and the transmissionloss is reduced.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method for improving the performance of an electrically small antenna used in a human body-centered wireless communication network and an electrically small antenna structure formed. Background technique [0002] The so-called electrically small antenna refers to the antenna whose physical size is smaller than 1 / 2π or 1 / 10 of the working wavelength. The reduction of the physical size of the electrically small antenna relative to the electric wave limits its radio performance, so the electrically small antenna usually has a low radiation efficiency. The disadvantages of narrow bandwidth and high transmission loss. [0003] The human body-centered wireless communication network is a wireless communication network centered on the human body, using electronic sensing devices implanted or worn on the human body to monitor human body signs information and signal tra...
