N2 - A 4-element array with unequal spacing is studied in this paper. The array elements are fed by L-probe. The array is resonant at the center frequency 900MHz, the GSM band. The wideband properties of the L-probe gives the bandwidth of the array within the GSM 900MHz band (870MHz ∼ 960MHz) with the SWR ≤ 1.5 from 845MHz to 980MHz (14.8%). Due to the unequal spacing of the array element, an asymmetrical radiation pattern is obtained. The upper sidelobe is suppressed, as required in mobile communication. The back lobe radiation reduces by adding 4 vertical walls on each edge of the ground plane.
