Abstract: This paper proposes design of parasitic microstrip antenna with multiple feed line for mobile communication applications at range frequency of 1800 – 2100 MHz. The purpose of adding multiple feed line is to enhanced the bandwidth of the proposed antenna. The multiple feed line used has an impedance of 100 Ohm and is placed on the edge of the patch parasitic microstrip antenna. The optimal bandwidth of the microstrip antenna is obtained by adjusting the dimensions and position of the multiple feed line. From the measurement results obtained return loss of -14.91 dB, VSWR of 1.44 at working frequency of 1800 MHz and bandwidth of 427 MHz with a frequency range 1715 MHz – 2142 MHz. . From these results it can be concluded that the banwidth of proposed antenna has met the criteria to be used in a mobile communication system.
Keywords: Antenna, parasitic, multiple feed line, wide band.
