Abstract

Current radars must meet the technological demands of today's world, which is why the modernization, replacement or design of any of its parts is a strategic step. The antenna unit does not escape this reality. In it, it is usual to find several blocks amoung which are the power dividers, especially in radars that use antenna array and in particular air exploration radar such as P18 and P12 use an unequal Wilkinson power divider at the center  frequency  of 160 MHz of  the  Very  High  Frequency  (VHF) band with  a power  ratio  at  the  ourput  ports  of 60%-40%. The  calculation  of the  components  is  carried  out  in Mathcad  and the  lumped   circuit  is simulated in AWR Microwave  Office.  From  the  results, Return  Loss (RL) of -45.18 dB, isolation between the output  ports  of  -49dB  and power ratio at  the  output of s31=-2.21dB and  s21=-3.98 dB in ports  3 and  2 respectively.
