Objectives: In this letter, the achievability of an unequal power divider utilizing a microstrip innovation as a part of the P/UHF band is designed. Methods/Statistical Analysis: Unequal power divider with 3-alternatives/approaches is composed in this research work, these are traditional microstrip configuration, power divider with input transformer and discretionary outline impedance (A-arbitary) is acquainted with control high impedance values and Power divider with general outline comparisons (Determination of Z1 or Z2 with required Impedances). Findings: At long last Power divider with general outline comparisons is figured it out. In this case the impedance of any one of the quarter wave impedance transmission line chosen is 30/35O which is most appropriate for impedance confinement of 10-60 ohm with a large power partitioning proportion radar applications where the side projection levels are most negative required. The unequal amplitudes of the 8-way power divider is designed utilizing Taylors 1-parameter method to get the side projections levels - 17 dB down from the fundamental beam. Application/Improvements: The 2-way and 8-way power divider was simulated using Method of Moments based Zealand IE3D software (MOM) an aggregate bandwidth of 40MHz was accomplished at an resonant frequency 0.43GHz. The simulated 2-way and 8-way unequal power divider is simulated and results are given. A prototype of 2-way unequal power divider with power levels P1 and P2 are 0.79622 and 0.89352 with power ratio of 1.1222 is fabricated to verify our proposed design. Measured results are given good agreement with simulated results to confirm our proposed design.
