Abstract	In case of single element antennas like Yagi-Uda, spiral, dipole, horn etc. have very little capability of variation antenna gain pattern. For better directivity, electronic tracking and reshaping of beam, array antenna is widely used in wireless network. Relative magnitude of feed currents, relative phases/separation between antenna elements, geometry of array are responsible for the shape of radiation pattern. In this paper linear array antenna with adaptive algorithm is used to achieve desired gain pattern at a desired angle of arrival (AOA). Linearly constraint minimum variance (LCMV) algorithm can be used quite comfortably for a desired gain incorporating Lagrange multiplier but side lobes can not be cancelled properly. This paper deals with combination of LCMV, sidelobe cancellation, LMS algorithm to achieve derided antenna gain pattern keeping sidelobe below a threshold level.
