Embodiment Construction
[0030] The present invention will be further described below in conjunction with embodiment and accompanying drawing.
[0031]The present invention designs and manufactures a reconfigurable planar array antenna based on digital code characterization. By controlling the bias voltage at both ends of the switch linear phase shifter to be ±1.5V, the switch linear phase shifter can switch between two There are different transmission channels with a phase difference of 180°, so that the radiation encoding unit has two encoding states of "0" and "1", which are used to construct a 1-bit digital encoding antenna. The present invention introduces the digital coding technology into the design of the reconfigurable array antenna, and constructs a pattern based on the digital coding representation. Each radiation coding unit in the reconfigurable planar array antenna contains only two numbers of "0" and "1". state, and the digital state is independently adjustable. By independently contro...
