An unconventional, yet quasi‐modular base station phased array architecture synthesis technique is proposed for multiuser fifth‐generation applications. By keeping uniform amplitudes and linearly progressing phases at the elements of an optimal irregular array, power‐efficient side lobe suppression is achieved for effective inter‐user interference mitigation. The layout irregularity is achieved within a slice of an array, which is repeated rotationally. The sequential rotation technique is applied to obtain modularity and improve the circular polarization characteristics. A modified k‐means clustering algorithm is used to form the optimal subarrays. The simulation results indicate that the proposed quasi‐modular topologies provide a good compromise between the side lobe performance and integrated array design complexity.
