2 way Wilkinson power divider for X band navigation radar

Abstract

A compact radar system becomes a necessity in order to build a lightweight navigation radar. Researches were conducted to create an integrated radar system in the form of one board of 9.3 GHz navigation radar system. Microstrip technology was used for its simple structure and miniaturization at high frequencies. Power divider as a part of the radar system was used to divide the signal from Voltage-Controlled Oscillator (VCO) to Transmitter front end and mixer on the Receiver end. This paper proposed the design and simulation of the Wilkinson Power Divider on Duroid RT5880 substrate using Advanced Design System (ADS) software. The S parameters were analyzed to see the performance of the divider. The proposed design already met the expected requirement of the power divider with more than -30 dB return loss, -3.059 dB insertion loss, and -29.541 dB isolation between divider output ports.
