Control of phase in radial line slot antenna for 5G communications at 60GHz

This paper shows the design of a radial line slot antenna for being used in indoor environments in the 60 GHz band of the future 5G communication systems. The antenna is designed to work in near field situation, creating a uniform field in a certain volume, improving the size of this volume with respect the use of uniform phase. The paper analyzes different configurations of phase on the slots and performs the design of the slot position and length on the upper plate of the radial line slot antenna.
