Reconfigurable antenna in programmable control

The invention discloses a reconfigurable antenna in programmable control, and belongs to the field of antennas. The antenna mainly comprises a servo circuit, a programmable voltage source, an antenna unit and an antenna array, wherein each transverse PIN diode forms one antenna unit, the antenna array is composed of a N-row M-line transverse PIN diode array; the servo circuit can be used for performing programming control on the programmable voltage source so that the programmable voltage source can output MN+M path voltages meeting the programming requirements, the MN+M path voltages output by the programmable voltage source are connected with MN+M electrodes of the corresponding transverse PIN diodes in the antenna array, and a frequency reconfigurable antenna in the programmable control, a linear array antenna in the programmable control and a plane array antenna in the programmable control can be realized by controlling the on-off of MN transverse PIN diodes. Through the adoption of the reconfigurable antenna in programmable control, the frequency reconfigurable antenna in the programmable control, the linear array antenna in the programmable control and the plane array antenna in the programmable control are realized.
