The simulation design includes power divider design determination of cable's length and the effect of tapering amplitude of the array antenna to the overall radiation pattern. At the end, results will

Basic PCB antenna dipoles were arranged in arrays to form a more directional antenna to increase gain while at the same time reduce back lobes which helps to decrease the effect of signal looping between donor and subscriber antenna in repeater system.

The base station antenna has a voltage standing wave ratio (VSWR) below 1.4, dual polarized, gain of around 16dB. Dipole antenna has been chosen due to its simplicity in antenna design and has been fabricated using brass. The dipole
