A multilayer and lightweight conformal antenna (MLWCA) is demonstrated using a U-slotted patch and stacked polyimide films. The antenna consists of a rectangular patch with a U-shaped slot placed above the stacked Kapton polyimide (KPM) and transparent polyester plastic film (TPPF), which provides enhanced bandwidth (BW) and bending performance. The antenna has a bandwidth from 1.18 GHz to 1.36GHz(14.1%) with a maximum gain of 8.0 dBi at 1.27 GHz.
The antenna is designed and analyzed for the flat case and conformed along the x – and y-axis to cylinders with a radius of 200,160,100, and 80 mm.
