An Improved T-Junction Power Divider Using Linearly Tapered Microstrip Lines

In this paper, a T-junction power divider using linearly tapered microstrip lines (MSLs) has been proposed; where the line to port 3 has also been tapered for achieving higher power dividing ratio between the output ports (ports 2 and 3). A method for theoretical analysis of the power divider has been presented approximately. The proposed T-junction power divider exhibits power dividing ratio of more than 10 dB over a broad frequency range of 1.7-5 GHz. The design is simulated in two different EM solvers (HFSS and CST) and their results are in well agreement with each-other which validate the same.
