What is it about?
This paper presents a new design concept of a beam steerable high gain phased array antenna based on WR28 waveguide at 29 GHz frequency for fifth generation (5G) full dimension multiple input multiple output (FD-MIMO) system. The 8×8 planar phased array is fed by a three dimensional beam-former to obtain volumetric beam scanning ranging from -60 to +60 degrees both in azimuth and elevation direction. Beamforming network (BFN) is designed using 16 set of 8×8 Butler matrix beam former to get 64 beam states, which control the horizontal and vertical angle. This is a new concept to design waveguide based high power three-dimensional beamformer for volumetric multibeam in Ka band for 5G application. The maximum gain of phased array is 28.5 dBi that covers 28.9 GHz to 29.4 GHz frequency band

Why is it important?
One major challenge in implementation of 29 GHz wireless communication is high path loss and to overcome this limitation, a high gain network is needed. Microstrip based networks are lossy at such high frequency and can't handle high power. Waveguide based networks are appropriate in Ka band because of low loss, high power handling capability, and reliability.
