Reconfigurable ultra-wideband dipole antenna and communication system

Abstract

The invention discloses a reconfigurable ultra-wideband dipole antenna and a communication system. The reconfigurable ultra-wideband dipole antenna comprises a first radiation section, a second radiation section and a third radiation section which are arranged in sequence, the first switching matcher is located between the first radiation section and the second radiation section, electrically connected with the first radiation section and the second radiation section and used for controlling the working modes of the first radiation section and the second radiation section; the second switching matcher is located between the second radiation section and the third radiation section, electrically connected with the second radiation section and the third radiation section and used for controlling the working modes of the second radiation section and the third radiation section; wherein the working modes comprise a high-frequency-band dipole antenna mode formed by the first radiation section and the second radiation section, and a low-frequency-band dipole antenna mode formed by the first radiation section, the second radiation section and the third radiation section. According to the embodiment of the invention, on the basis of ensuring the working frequency bandwidth of the antenna, the gain and reliability of the antenna are ensured, and the size of the antenna is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular to a reconfigurable ultra-wideband dipole antenna and a communication system. Background technique [0002] As a conversion device between electrical signals and electromagnetic wave signals, antennas are indispensable basic components in wireless communication systems. At present, under the background of the new generation of communication technology (software radio) and the need to prevent leakage or interference during the communication of frequency hopping radio stations, the requirements for the operating frequency bandwidth of the antenna are getting wider and wider. In the prior art, reconfigurable technology has been paid attention to because of its flexible switching and wide frequency coverage. However, the existing reconfigurable ultra-wideband antennas are usually complex in structure, large in size, large in loss, and poor in reliabil...
