A Dual-Port Bessel Beam Launcher for Microwave Wireless Power Transfer

A dual-port fed Bessel beam launcher designed for 10 GHz microwave wireless power transfer is proposed in this article. The annular slot rings placed on the top plane is excited with a two-port coaxial probe fed circular loop placed in the middle layer. The feed circular loop is designed such that the structure exhibits a parallel combiner feature at the design frequency. The proposed structure is designed and simulated in the full wave numerical solver of ANSYS HFSS. The obtained results indicate a Bessel beam generation within a non-diffracting range of $6\lambda$ and parallel combiner nature at 10 GHz.
