Design and simulation of 8-way unequal amplitude equal phase RF feeder network using conventional microstrip technology for 430MHz Tropospheric wind profiling radar

In this paper, the feasibility of an 8-way unequal amplitude equal phase power splitter using a conventional microstrip technology in the 430MHz UHF band is proposed for Tropospheric wind profiling radar. Feeder network with unequal amplitude is designed based on the side lobe level requirement -17db down from the main beam. The theoretical design and simulated results are presented to verify our proposed design. The main advantage of this present design is to reduce the complexity in Transmit-Receive module.
