The invention provides a two-dimensional array electronic scanning antenna, the antenna includes N parallel composite left and right hand leaky wave antennas; the composite left and right hand
leaky wave antenna includes M serial composite left and right hand
radiation units; each composite left and right hand leaky wave The antenna is connected to a feed channel; the feed channel is composed of an
amplifier, an attenuator and a phase shifter connected in sequence, and the
amplifier and attenuator are used to control the
excitation amplitude and optimize the performance of the antenna pattern; the phase shifter is used to control each The phase of each channel; the antenna has the characteristics of simple structure and low cost. Based on the above-mentioned two-dimensional array electronic scanning antenna, the present invention also provides a scanning method of the two-dimensional array electronic scanning antenna, which can realize scanning in two-dimensional space without blind spots.
