Abstract:In this paper linear array antenna mounted along the missile body is presented. Linear array consists of patch type radiating elements. Antenna is able to operate at lower frequency (L or S band) and could be compatible with long range acquisition radars. Dimensions of linear antenna array are not related with missile diameter and linear array could be position at the missile with small diameter. Linear array, collinear with antenna body forms many simultaneous beams, narrow in the planes collinear to missile and wide in the plane orthogonal to missile. Depending of element phasing, radiation pattern could be formed in the form of different conical shapes with apex at the missile longitudinal axes. It means that array simultaneously receive signals from almost full sphere. Array has maximum gain at the plane orthogonal to missile and it can be decreased four dB at the cone angle of 70 degree.
