Wilkinson topology-based 1:6 power divider for L-band frequency application

In this paper, a 1:6 power divider to work at L-band frequency application is proposed. The power divider which is intended to divide or split a signal power from a device into some other devices is designed based on a Wilkinson topology and developed using microstrip technology. The proposed power divider is comprised of 2 stages; the first stage is 1:2 power divider, whereas the second stage consists of 1 pair of other 2 Wilkinson topology power dividers with the extension to 3 output ports. The design of power divider is deployed on an Arlon DiClad527™ dielectric substrate with relative permittivity of 2.5 and thickness of 1.6mm. From the design result, it shows that the proposed power divider demonstrates a good performance in the desired frequency range with the insertion loss of 7.8dB for frequency range from 1GHz to 2GHz, the return loss less than 12.3dB at frequency of 1.5GHz, the isolation less than 12.8dB at frequency of 1.5GHz.
