| Popis: | This research work focuses on the design and simulation of a planar dipole antenna for 1800MHZ Band for Global System Mobile GSM application using Computer Software Technology CST studio software. The antenna is structured on a fire resistance FR4 substrate with a relative constant of 4.3 S/m. Two types of feeding configuration are designed to feed the antenna in order to match 50 ohm transmission lines which are via-hole integrated balun and quarter wavelength open stub. The via-hole is capable to provide maximum return loss of 25dB, bandwidth of 18.4 percent and the voltage standing wave ratio (VSWR) of 1.116 V at optimum dimension of length 59mm and width 4mm, the bandwidth is improved 25 percent to 30 percent by extending the width of the antenna 8 mm to 10 mm followed by deterioration of return loss value to 15dB. While the open stub at length of 67 mm, the width of 6 mm and height 1.6mm will provide max return loss of 47.88dB and bandwidth of 17 percent with VSWR 1.008 less than 2. The way that the antenna substrate has influenced the performance of the antenna. The lower relative constant will result in the higher return lows, narrower bandwidth and better radiation pattern in trade-off the resonant length Via-hole and then the quarter wave open stub are most convenient for practical implementation.
