20dB Directional coupler for LTE band application

摘要

This paper presents a structure of Directional coupler for LTE band application is presented, which has a coupling level accuracy 20dB at 2.4 GHz frequency and FR4 dielectric material use. The design uses single section coupled line method that simulated using simulation software ADS 2011.10. In this paper a lumped element method is also implemented and compare with the conventional design approach and found that directivity and isolation is reasonably good for LTE application.
