In this study, a broadband antenna system with filter structures is designed. The design is proposed for smart houses. The system covering 3G, Wi-Fi and 5G frequency bands can handle for different applications by the distributed filtering approach. The proposed prototype utilizes one antenna for different applications by using three filtering structures and power dividers. The simulations are done on HFSS and AWR for the antenna and filter designs, respectively. The prototypes are produced and S-11 parameters and far-field radiation pattern measurements are carried out for whole system. The far-field radiation pattern of the antenna is measured in an anechoic chamber. As the materials substrates, Rogers 4003 and FR-4 are used.
