Such as the article published by B.Sanz-Izquierdo et al. in the 2006 First European Conference on Antennas and Propagation: Ultra-Wideband Wearable Button Antenna (UWB WEARABLE BUTTON ANTENNA) announced a hollow double-layer antenna, such as figure 1 As shown, the first layer is a cone, and the second layer is a cylinder. The coaxial bottom feeding method is used to feed the antenna. Because the surface of the antenna is covered with closed metal, it is not convenient for actual processing, and it cannot be conveniently fixed on the clothes.

The invention discloses an ultra-wideband antenna fixed on clothes. The main problem that the conventional antenna is difficult to machine and wear is solved. The antenna consists of a radiation unit (1), an antenna medium (2), a floorboard (3) and a coaxial line (4). The antenna medium consists of the clothes of a user. The radiation unit is vertically fixed on the surface of the clothes. The floorboard is symmetrically fixed on the bottom surface of the clothes at the vertical fixing position of the radiation unit. The radiation unit and the floorboard are connected with an inner core and an outer core of the coaxial line for feed respectively. The radiation unit consists of two layers of fastener type metal bodies which are integrated, wherein a first layer (101) adopts a hollow cone, a round through hole is reserved in the bottom surface of the hollow cone, and four nicks are reserved in the upper part of the hollow cone; and a second layer (102) adopts a hollow cone, and a round through hole (103) is reserved in the lower part of the hollow cone. The coaxial line feeds to the radiation unit through a round hole (301) in the center of the floorboard. The ultra-wideband antenna can cover an ultra-wide frequency band, and can be easily machined and conveniently fixed on the clothes.
Description
technical field [0001] The invention relates to the technical field of wireless communication, and relates to an antenna, in particular to an ultra-wideband antenna fixed on clothing. technical background [0002] In recent years, with the continuous development of science and technology, the volume of electronic devices has become increasingly miniaturized. People expect that electronic devices such as computers can be worn on people's bodies, and they can be integrated with clothes without affecting the appearance of clothes. However, it is difficult for traditional devices to achieve this, so people hope to redesign various electronic devices to make them more suitable for wearable systems. As an essential part of wireless communication, the antenna can be separated from the communication equipment and sewn on people's clothing as an independent part, so the shape of the antenna can be changed to make it more concealed and more suitable for wearable systems . Due to its...
