Abstract

In this paper, a comparative study has been conducted to analyze the bandwidth enhancement on Branch Line Coupler when using magneto-dielectric polymer substrate (PDMS-Fe304) also known as (Polydimethylsiloxane-Iron Oxide). A branch line coupler based on magneto-dielectric polymer substrate was designed and simulated to evaluate the contribution of such promising material in microwave component performance. The purposed branch line coupler was design and simulate to ensure branch line coupler that used magneto-dielectric polymer substrate can achieved higher bandwidth enhancement. All of the branch line coupler will operated on 2.45 GHz operating frequency. The result for (S11) parameter on purposed branch line coupler using magnetodielectric polymer substrate was show an astonishing enhancement in bandwidth up to 1260 MHz compare to 950 MHz and 720 MHz for Rogers and FR-4 substrate. The phase difference on the magneto-dielectric polymer substrate (PDMSFe304) show a significant improvement bandwidth at 2 to 2.7 GHz with 90° ± 5°, better than normal conventional substrate branch line coupler.
