Abstract :
A low profile antenna consisting of a wideband monopole over an artificial magnetic conductor (AMC) is presented in this paper. The AMC is a dual band structure, manufactured on 3.2mm thick FR-4 substrate with the reflection phase in the 2.0 GHz and 5.8 GHz ranges. A wideband printed circular disc monopole antenna uses this dual band AMC as a ground plane resulting in a low profile multiband antenna system with a height of 7.8mm. The frequency bands covered are at GPS (1.57542 GHz), DCS (1.710-1.880 GHz), PCS (1.850-1.990 GHz), UMTS (1.925-2.175 GHz), WLAN (2.4-2.485 GHz), WiFi (5.15-5.825 GHz) and V2X (5.76-5.84 GHz). It is demonstrated that the boresight gain increases when the AMC is used as a ground plane for the antenna in conjunction with a large metal plate.
