In this paper, we design codebooks for supporting beamforming in 60 GHz frequency band. The proposed codebooks support both discrete and continuous phase resolution, respectively. The codebooks with discrete resolution were derived following the concept initiated by TG3c in IEEE 802.15.3c standard while the codebook with continuous resolution is based on Kaiser-Bessel windowing function. The designed codebooks give weight vectors that have reasonable level of side lobe and can be used in 60 GHz systems employing analog and digital phase shifters. The codebooks were created by considering the main features of linear array such as array gain, side lobe level, directivity loss and half-power beamwidth of the radiation pattern. The simulation results show that the weight vectors of the designed codebooks improve the performance of linear arrays in terms of power of side lobe, directivity loss, and output SNR of beamforming receiver. The designed weight vectors are frequency independent; in this case, they are both applicable in wideband and narrowband beamforming systems.
