This study proposes the design of a three‐element uniform linear array antenna using the method of ‘ compressed cosines ’ . An approximation of an ideal array factor (AF) – Kronecker‐ δ with third degree optimal polynomial was performed and some Luneburg lenses were used to realise the array antenna. The designed array antenna has remarkable properties: broadband, narrow beam without side lobes, and with constant selectivity of the AF. A Matlab simulation was also demonstrated and a five‐element, two‐dimensional array antenna was designed with the proposed method.
