CONCOLUSIONS
In this paper, an array patch antenna designed for 40obeam steering in 2.4 GHz central frequency. The antenna had four
radiating elements fed by microstrip feed lines and parallel feeding
network consists of Wilkinson power splitters. As the objective was to
steering beam in a specific direction, phase shifters were applied to
make proper delay in the line. The return loss at 2.4 GHz was -35 db.
The antenna had its highest gain at 40 degree.
