Abstract :
This paper present the comparison of base station antenna operating at 900 MHz GSM network with 65° and 105° horizontal beamwidth. 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 antennas are slanted to either +45° or -45° to increase the base station antenna sensitivity and the user capacity of a base station. The VSWR of the base station antenna was measured by using Agilent 8722ES Network Analyzer and the radiation pattern was done in Anechoic Chamber in Multimedia University, in Cyberjaya, Malaysia.
