This research discuss about design and prototype of Wilkinson power divider with a microstrip transmission line. Power divider that is designed has one input port and two or more output ports with the input and output line characteristic impedance of 75Ω. Power divider is designed to be applied to the analog and digital terrestrial television antenna receiver in Indonesia at a frequency of 479 - 799 MHz using FR4 substrate material (dielectric constant e{open]r = 4.3) and a copper conductor material. Design and simulation of power divider is done using the CST Microwave Studio. The simulation results of power divider in the frequency range 479 - 799 MHz shows the value of S11, S22, and S33 ≤ -15 dB, S21 value between -3,054 - -3,136 dB, the value S31 between -3.052 - -3.137 dB, and the value of S23 and S32 ≤ -15 dB. Results of measurement of power divider in the frequency range 479 - 799 MHz shows that the minimum S11 value is -14.38 dB. The minimum S22 value is -14.97 dB. The minimum S33 value is -15.17 dB. The minimum S21 value is -3.68 dB and the maximum is -4.35 dB. The minimum S31 value is -3.51 dB and the maximum is -4.37 dB. The minimum S23 value is - 17.12 dB. © 2006-2016 Asian Research Publishing Network (ARPN).
