Miniaturization of Bagely Polygon Power Divider using Dual Transmission Line Technique

Abstract

In this paper, the technique of dual transmission lines is applied to the quarter wavelength arms of the Bagley Polygon Power Divider and the overall size of the power divider is considerably reduced. The ( λ/4) arm line between the 1st port and the 2nd and 3rd port is replaced by a dual arm with lengths ( λ/6) and ( λ/3) each and the ( λ/2) arm between the 4th port and the 2nd and 3rd port is replaced by a length of ( λ/12). The proposed design is simulated in ADS and the return loss performance is found to be greater than 18dB and the power division between the output ports is equal and approximates to the ideal value. A size 38.5% is achieved.
