Abstract :
The application of the principle of sequential rotation in a smart antenna terminal for broadband communication is presented. Different schemes of rotation have been applied to the array arrangement and compared. The single radiators are linearly polarized microstrip patches fed by a circular ceramic-filled waveguide. An exemplary array size has been chosen for simulations and the results are presented for the different sequential rotation schemes.
