Abstract

The invention discloses a reconfigurable antenna and belongs to the field of wireless communication. The reconfigurable antenna comprises a plurality of antenna radiating elements for transmitting signals and a metal base plate as a reflecting plate, wherein the antenna radiating elements are located above the metal base plate and are arranged side by side in parallel, each antenna radiating element is connected with the side end of an adjacent antenna radiating element to achieve electrical contact; the antenna radiating element includes a first metal plate and a second metal plate between which a gap is arranged; the first metal plate and the second metal plate are connected by a first RF switch; and the RF switch and an adjustable lifting device achieve current distribution between theantenna radiating elements, the resonance characteristic of the antenna, and reconfigurable antenna bandwidth and gain.

Description

technical field [0001] The invention relates to a reconfigurable antenna in the technical field of wireless communication, in particular to a reconfigurable ultra-wideband antenna controlled by a radio frequency switch. Background technique [0002] At present, in the use of UWB antennas, ridge horn antennas, Vivaldi antennas, logarithmic periodic antennas and UWB reconfigurable antennas are mainly used. The ridge horn antenna and the Vivaldi antenna are volume antennas with good bandwidth characteristics, but the antenna volume is relatively large; the logarithmic periodic antenna is a frequency-invariant antenna, and the bandwidth of the antenna is related to the number of vibrators. The axial length of the antenna is too long, and the application The environment is limited; most of the commonly used ultra-wideband reconfigurable antennas at this stage are planar reconfigurable antennas. By controlling the switch, the current distribution of the antenna radiating element i...
