Abstract
An antenna array composed of four inclined microstrip Yagi antennas is proposed for a direction finding (DF) system operated in L band. Each element antenna is designed to have a tilted beam toward a central array axis in order to have high gain in the boresight axis of the antenna array. In comparison to a patch antenna array, having the same structure, antenna array gain is improved by a 2.3 dB maximum around the array axis, monopulse slope is increased by 72% and the linearity of the slope is improved significantly. Also, axial ratio is improved by 3 dB max within ±25° from boresight.
