Compact 2-Way Power Divider for IoT Application

The utilization of power dividers covers a vast range of applications such as the Internet of Things (IoT). For this purpose, the need for having a robust and ergonomic electronic device is crucial. Bulky size could barely integrate onto the human body due to its weight that could be very difficult to implement. Hence, this paper presents the design of a compact power divider for IoT applications. It was designed on a substrate Rogers 4350B, ε_r=3.48, tan δ= 0.0037 and h=0.17mm. The design was meant to be operated at 2.4GHz frequency with the output of equally 3dB power division on the output port. Wilkinson design was implemented to perform the design of power divider which will be simulated using Computer Simulation Technology (CST) microwave studio simulation tools. Parameter sweep was done to its width of transmission line at 0.21mm and 0.31mm to optimize the performance of the design. The simulated result was then compared against measured results in which S-parameter was evaluated in terms of input return loss, isolation and power division. Simulated and measured results showed that 0.21mm width of the transmission line performs better as compared to 0.31mm width of the transmission line. (paper)
