This paper discussed the simulation and analysis for developing array antenna operating from 450 ... more This paper discussed the simulation and analysis for developing array antenna operating from 450 MHz to 470 MHz using bended dipole antenna developed in Telekom Research &amp;amp;amp;amp; Development, Cyberjaya. The simulation design includes power divider design determination of cable&amp;amp;#39;s length and the effect of tapering amplitude of the array antenna to the overall radiation pattern. At the end, results will

Design & development of high gain antenna arrays for CDMA 450

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
