Embodiment Construction

[0025] The invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] The invention combines the wearable antenna with the button on the clothing, and the designed button antenna can be easily integrated into the clothing, figure 1 and figure 2 It shows the overall side view and top view of the antenna. The antenna consists of two layers of substrates, which are connected and supported by a hard coaxial cable. The lower substrate is made of square flexible felt material, which can be perfectly sewn onto clothing. The back of the felt is a complete metal ground. Open a round hole in the ground and the center of the base plate to facilitate the passage of hard coaxial cables. image 3 and Figure 4 Shown is the structure of the upper and lower surfaces of the upper substrate. The upper substrate is a circular FR4 (epoxy resin board) material. Cutting corners and opening U-shaped grooves on the patch can achieve directional cir...

Abstract

The invention relates to a dual-band dual-mode button antenna, and belongs to the field of design and application of wearable antennas. The antenna comprises an upper dielectric substrate and a lower dielectric substrate which are connected and supported through a hard coaxial line; the lower-layer substrate is made of a square flexible felt material, and the back surface of the felt is a complete metal patch; the upper-layer substrate is made of an FR4 material, the front surface of the upper-layer substrate is a square metal radiation patch, the square metal radiation patch is provided with a cut corner, and the square metal radiation patch is provided with an asymmetric U-shaped groove. Four metal branches are led out from the four sides of the square metal radiation patch, extend to the edge of the upper substrate and are bent, the back face of the upper substrate is a circular metal patch slightly smaller than the substrate, and a circular hole is dug in the circular metal patch, so that a feed cable can be connected to feed power to the radiation patch on the front face. According to the present invention, different radiation modes are presented in different frequency bands, and a circular polarization effect is realized in a directional mode.

Description

technical field [0001] The invention relates to a dual-band dual-mode button antenna, which belongs to the field of design and application of wearable antennas. Background technique [0002] Wireless Body Area Network (WBAN) is a short-distance, low-power, High reliability wireless communication network. According to the location of the sensors participating in the communication, the communication links can usually be divided into internal communication, body surface communication and external communication. Wearable antennas are key components for wireless body area network communications that work around the human body. Considering the needs of practical applications, we usually have the following requirements for wearable antennas: 1) Realize different radiation patterns in different frequency bands, Among them, the omnidirectional radiation mode is used for body surface communication, and the directional radiation mode is used for in vitro communication; 2) The physica...
