Abstract

A novel compact 4-way power divider is presented here, which consists of 1/64^th mode elliptically curved substrate integrated waveguide (SIW) resonators and radial transmission lines. A direct coaxial fed circular patch acting as the radial transmission line is connected with four elliptically curved 1/64^th mode SIW resonators, and these resonators are then connected to output terminals. An equivalent circuit model is developed to understand its behavior. It is designed to operate at 3.6 GHz covering the frequencies assigned for 5G in sub-6 GHz band. Conventional PCB techniques are used to fabricate the prototype. The measured bandwidth is 2.2 GHz, ranging from 2.5 GHz to 4.7 GHz, for which the return loss is less than -10 dB. Also, the transmission coefficient between input and each output for the above-mentioned frequency band is -6.4±0.5 dB. It has a very compact footprint of 0.32λ_g², which is at least 40% smaller than various SIW based state of the art power dividers.
