Realization of Semicircular 2 Way Optimal Power Divider for GNSS

Abstract

This paper gives the design of optimized semicircular 2 way equal power divider particularly for GNSS applications. The designed power divider is derived from the basic Wilkinson configuration using the quarter wave Transformers with the novel optimized geometry. The 2 way equal power divider is implemented at a center frequency of 1175 MHz- L5 Band of Global Navigation Satellite System. The power division results shows a efficient Insertion Loss (S21 & S31) values as −3.016dB, −3.018 at ports 2 and 3 respectively. The Return Loss S11 at all three ports is more than −30dB. The significant Isolation between the ports 2 and 3 is −30dB. The results are specifically confined to the applications of Satellite communication.
