The invention relates to a novel high-performance conformal array antenna, and solves the technical problems of
low gain,
narrow bandwidth and poor anti-interference capability. The antenna comprisesconformal array antenna units arranged in an array, wherein the conformal array antenna units use a
traveling wave antenna feeding structure with two-port feeding, and the size is reduced through thefractal technology, so that the
radiation influence of a curved surface on the antenna units is reduced; a
slot coupling feed structure is adopted to improve the bandwidth of the antenna units, reducethe
surface wave loss of the antenna unit and enable the
radiation element to be better isolated from the
feed network. A
liquid crystal tuning circuit is adopted to apply a
liquid crystal material to an antenna unit; the
liquid crystal equivalent
dielectric constant is changed through electric tuning, so that the resonant frequency of the antenna unit is changed, the
radiation characteristic ofthe conformal array antenna unit in a required
frequency band is controlled, the contribution of different antenna units to a main wave beam is controlled, the anti-interference capability is enhanced, the problem is better solved, and the conformal array antenna can be used in an antenna.
