5G wireless communication is next major phase of mobile communications standards beyond the current LTE-Advanced. In order to meet 5G faster speed (1-10 Gbps), millimeter wave frequency band has been recommended for 5G wireless communication. Ka band has been targeted for short-range, high data rate communication. 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.
