Title:
ANTENNA STRUCTURE AND ANTENNA SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/134429
Kind Code:
A1
Abstract:
The present disclosure provides an antenna structure and an antenna system. The antenna structure comprises a dielectric substrate, a twin lead, a first dipole antenna, a second dipole antenna and a reconstruction structure; the dielectric substrate comprises the front surface and the back surface which are opposite to each other; the twin lead comprises a front conductor and a back conductor which are parallel to each other; the first dipole antenna comprises a first radiation arm and a second radiation arm, and the second dipole antenna comprises a third radiation arm and a fourth radiation arm; the reconstruction structure comprises a front surface unit, a back surface unit and a switch device; both ends of the switch device are respectively connected to the front surface unit and the back surface unit; the twin lead is used for transmitting a radio frequency signal and a control signal. The on/off of the switching device is controlled by means of the control signal so as to introduce the impedance or phase value of the reconstruction structure into an antenna structure, so that the shape of a directional diagram is changed, gain magnitude switching and radiation beam pitch angle switching are realized, and the directional diagram of the antenna is reconstructed.
