Abstract


Radiation pattern controlling of antenna array can be done by change some parameters such as the geometry of antenna array, distance among the element antenna array, amplitude and in phase of excitation. Controlling of antenna array radiation pattern to certain geometry and distance among an element and the amplitude of a constant current can be done by device of phase shifter. This research made a device to shift the phase using switched line method to condition phase 300, 600 and 900. The result show the phase 300, 600 and 900 obtainable with size a cable inter of different elements are 0 λ, 1/2 λ, 1/16 λ.
