Embodiment Construction
[0013] The present invention will be further described below in conjunction with drawings and embodiments.
[0014] The technical scheme adopted in the present invention is: the high-isolation slot antenna array is composed of three slot antennas 1 placed together and whose radiation polarization directions are orthogonal to each other; The microstrip feeder 3 and the metal ground plane 4 are composed of a radiation slot 5 and a plurality of isolation slots 6 on the metal ground plane 4; the radiation slot 5 is rectangular in shape; the isolation slot 6 is located around the radiation slot 5, and its The shape is a narrow rectangle; the isolation slits 6 are all parallel to each other, and the long side direction of the radiation slot 5 is perpendicular to the long side direction of the isolation slit 6; the isolation slits 6 are all parallel to each other, and one end of the isolation slit 6 is either short-circuited or extended to The edge of the metal ground plane 4 makes t...
