Description

In this paper, the new method of obtaining the radiation pattern having equal minimum levels of the linear array antenna. Procedures of this method are as follows : First, some specific directions in the radiation pattern and the minimum level are determined using level control method. Second, two specific directions on the adjoining sidelobes are almost assimilated. Finally, the amplitudes of the current are calculated using them. And the radiation pattern is nearly isotropic by this method. The radiation pattern can be obtained by controlling the amplitudes of the currents only. The amplitude of the currents can be designed by using the digitally controlled attenuators. As the attenuators can be accurately changed in steps of 0.03 dB or less, the resulting quantisation error will affect the radiation pattern. Then the effects of quantisation error on the radiation pattern are verified.
