The invention discloses a miniaturized Ku full-band
satellite antenna array. The
antenna array comprises an antenna body and a feed structure for feeding the antenna body; the antenna body is formed by arranging a plurality of antenna units; each antenna unit comprises an upper
dielectric plate, a middle
dielectric plate and a lower
dielectric plate which are stacked from top to bottom; a
radiation patch is printed on the upper surface of the upper
dielectric plate; a grounding reflection plate is printed on the lower surface of the lower
dielectric plate; a grounding plate is printed on the upper surface of the middle
dielectric plate; two horizontal polarization feed
microstrip lines with opposite feed directions and two vertical polarization feed
microstrip lines with the same feed direction are printed on the lower surface of the middle dielectric plate; a vertical rectangular gap is formed in a position, perpendicular to the end part of each horizontal polarization feed microstripline, of the grounding plate; a horizontal rectangular gap is formed in a position, perpendicular to the end part of each vertical polarization feed
microstrip line, of the grounding plate; the two horizontal polarization feed microstrip lines are connected through a horizontal polarization
coaxial probe; the two vertical polarization feed microstrip lines are connected through a vertical polarization
coaxial probe; and both the horizontal polarization
coaxial probe and the vertical polarization coaxial probe are connected with the feed structure. Narrow antenna width and high
gain can be obtained.
