Abstract

The invention discloses a reconfigurable ultra-wideband antenna, which comprises a planar flexible substrate and liquid metal packaged in the planar flexible substrate, wherein the liquid metal presents a certain planar pattern in the planar flexible substrate and is used as a metal antenna of the ultra-wideband antenna; the planar pattern formed by the liquid metal is provided with one or more electromagnetic gaps; and the signal frequency band, the radiation direction and the radiation intensity of the ultra-wideband antenna are adjusted by stretching and / or bending the metal antenna in theplanar flexible substrate. According to the invention, the ultra-wideband antenna is made by adopting a flexible material, so that the bending and stretching requirements of the ultra-wideband antennacan be met, and the frequency conversion and orientation functions of the ultra-wideband antenna are realized.

Description

technical field [0001] The invention belongs to the technical field of ultra-wideband antenna frequency conversion, in particular to a reconfigurable ultra-wideband antenna. Background technique [0002] Ultra Wide Band (UWB) technology is a new type of wireless communication technology. It solves the major problems related to propagation that have plagued traditional wireless technology for many years. It has the advantages of insensitivity to channel fading, low power spectral density of transmitted signals, low interception capability, low system complexity, and positioning accuracy of several centimeters. In recent years, with the rapid development of communication technology, antennas have been widely used in electronic countermeasure systems, ultra-wideband radar, satellite communication and other fields, and there are also extensive demands in high-speed wireless LAN, home network and wireless telephone. Therefore, it is of great practical significance to design an u...
