Embodiment

[0029] A dual-band wearable antenna with switchable working modes, such as image 3 , Figure 4 , Figure 5 As shown, it includes a circular dielectric substrate 1, a grounding plate, and a circular radiation patch 2. The circular dielectric substrate 1 is composed of two upper and lower dielectric substrates with the same size, and the grounding plate is located on the lower layer of the circular dielectric substrate 1. The lower surface of the sheet, the radiation patch 2 is located on the upper surface of the upper substrate of the circular dielectric substrate 1; wherein, the radiation patch 2 is circular in shape, located at the center of the upper substrate of the circular dielectric substrate 1, and radiates The left and right sides of the patch 2 are provided with rectangular grooves with the same shape and size and distributed symmetrically.

[0030] By loading segmented ground metallization vias 3 at an appropriate distance from the center of the radiating patch 2,...

Abstract

The invention provides a dual-band wearable antenna with switchable working modes, and belongs to the technical field of antennas. The adopted technical scheme is that the dual-band wearable antenna comprises upper and lower layers of dielectric substrates. A radiation patch is arranged at the upper surface of the upper layer substrate. A grounding plate is arranged at the lower surface of the lower layer substrate. The radiation patch and the grounding plate are connected by segmented metalized through holes. Symmetrically distributed rectangular grooves are arranged at the left and right sides of the metal radiation patch. The segmented metalized through holes are connected by a segment of conductor strip. The antenna adopts a coaxial probe for direct feed. A coaxial internal conductor extends to the radiation patch from the grounding plate. A circle of circular groove is etched around a feeding point so as to increase inductive reactance, and thus impedance matching is facilitated. Problems in the prior art that the wearable antenna cannot meet the requirements of people for miniaturization, integration and wearing facilitating are mainly solved by the dual-band wearable antenna with the switchable working modes.

Description

technical field [0001] The invention belongs to the technical field of antennas, and relates to a dual-band wearable antenna with switchable working modes. Background technique [0002] In recent years, with the development of mobile communication technology, people's user experience has been greatly improved, and the application of many new technologies has subverted people's cognition of traditional communication methods. As people carry more and more electronic devices, how to interconnect the electronic devices distributed in various parts of the human body to form an efficient working system, so as to realize specific functions, has gradually become a research hotspot. The human body center communication system is convenient Came into being. The body-centered communication system takes the human body as the center, constructs a system network, and enables the electronic devices distributed in various positions of the human body to realize interconnection, so as to real...
