A Wide-band Wide-beam Conformal Antenna Based on AMC

In this paper, a conformation dipole element working in L band is designed. The antenna bandwidth is broadened by eliciting two pairs of overlapping metal arms on both sides of the cell wall, and the AMC surface of air mixture medium is loaded below the dipole antenna to broaden the reflection phase bandwidth of AMC, reduce the antenna profile height, and broaden the beam width. The final design antenna achieves 43.5% relative bandwidth at

reflected phase bandwidth at AMC, and a 3dB beam width of 100° within the AMC reflection bandwidth.
