Abstract In this paper, a new design single feed multi-band antenna is presented. The proposed antenna is designed to operate at the 1.278GHz, 2.8GHz, 5.7GHz, and 10GHz frequency bands which cover the Galileo satellite positioning system (1.278GHz), WLAN (2.8GHz), WIMAX (5.7GHz) and the radar applications (10GHz), respectively. The antenna has a compact size, it is printed on an FR4 substrate of dimensions (60mm×27.5mm×1.67mm) placed on a ground plane of 60mm×17.5mm×0.035mm dimensions. To improve the radiation performance of the proposed antenna, an artificial magnetic conductor (AMC) was used as a reflector plane with dimensions of 13.5mm × 13.5mm × 1mm. The simulated and measured results are in good agreement and show the significant improvement of the gain value of the multiband antenna with AMC which is a required propriety for novel wireless communications systems.
