Abstract
The invention discloses a button antenna for realizing directional radiation based on an incomplete AMC structure. The button antenna comprises a top circular medium, a button antenna structure, a bottom circular medium, a full-fabric medium substrate, a conductive fabric bottom plate, a conductive fabric microstrip line and the incomplete AMC structure, the metal columns and the dielectric columns form a button antenna structure, the incomplete AMC structure is located between the top circular medium and the bottom circular medium, and the conductive fabric microstrip line is located on the side close to the incomplete AMC structure. According to the antenna, under the condition that the transverse size of the button antenna is not additionally increased, original omnidirectional radiation of the button antenna is changed into directional radiation by adding the incomplete AMC structure, and the gain of the wearable button antenna is improved while backward radiation is reduced.
Description
technical field [0001] The invention relates to the technical field of radio frequency antennas, in particular to a button antenna for directional radiation based on an incomplete AMC structure. Background technique [0002] With the development of wearable technology, the research of body area network has promoted the research of directional radiation antenna along the body surface. Therefore, this patent is on this basis, by using the incomplete AMC structure technology, to study the button antenna suitable for this application, and realize the directional radiation of electromagnetic waves along the body surface direction on its low-profile and small-area antenna characteristics. Contents of the invention [0003] The purpose of the present invention is to provide a button antenna that realizes directional radiation based on an incomplete AMC structure, aiming at solving the problem of realizing directional radiation without increasing the lateral size of the button ant...
