Compact CPW-fed ultra-wideband (UWB) antenna using denim textile material

A compact and flexible CPW-fed UWB antenna is designed using denim material. The proposed structure consists of an eclipse patches and modification of ground plane to obtain an impedance bandwidth between 2.52 GHz and 13.35 GHz. The dimension of antenna is 35 mm × 45 mm with thickness of 0.78 mm. The antenna is simulated using CST Microwave Studio. The structure is then fabricated using copper tape as radiating element and denim textile as substrate. The dimension of antenna are studied and optimized to obtain UWB requirement. The simulated and measured result are compared and analyzed in this pape
