Abstract

This paper presents unequal microstrip power divider designs using the hierarchal genetic algorithm (HGA). The dividing ratio and return loss are the design specifications leading the evolution direction. By employing the HGA chromosome formulation, the system structure and its associated parameters can be minimized in a simultaneous manner. The computational performance of the design methodology is enhanced with the use of a parallel computing platform. The subsequent power dividers derived from the design have been fabricated, tested, and experimentally verified. Its performance matches very well with the result obtained from the simulation study. ยฉ 2003 Wiley Periodicals, Inc.

mum is in the end-fire direction with higher cross-polar level and a gain of 3 dBi is observed over the VSWR BW. The area of the proposed compact MSA is 15 cm 2 , which is only 6% of the corresponding unslotted RMSA, which results in a better BW but a reduced gain. ## 6. CONCLUSION A compact varia
