To guarantee the simulation results, one of the proposed structures is fabricated and measured (namely the characteristics of S 11, E-, and H-plane patterns) which shows acceptable consistency with measurement results. The feeding network for array is an eight way Wilkinson power divider (WPD). The structure of feeding parts is the same but the radiation elements are different.
The proposed antenna arrays consist of eight single elements.
In this paper three different multi stub antenna arrays at 27–29.5 GHz are designed.
