A transmitarray antenna working at 28 GHz is proposed as a base station for novel indoor communications, including 5-G, Internet of Things (IoT) and wireless power transfer. This antenna produces a near-field coverage area in a desire area wherein the device should be found, giving them a total connectivity with external but also internal networks. Concerning the feeder, instead of using a single feeder configuration a cluster of them is selected. This cluster works in the 28 GHz band but using different channel which improves the capacity of the base station. In addition, a Phase-Only Synthesis (POS) is carried out in order to improve the features of the near-field coverage but only for the central feed and the final performances are evaluated for all the spots.
