In this paper, a compact ultra-wideband (UWB) antenna with triple notch bands is proposed. By etching out two ESRR of different dimensions in the radiating patch, two band-notched properties in the Wi-MAX (3–3.7 GHz), WLAN (5.125–5.825 GHz) are o

For half-space (Z>0), homogeneous, collisonal and warm plasma, the expressions for fields and penetration depth δ/δe (in the unit of ion collisionless cold plasma penetration depth, i.e., when vi=0, υ0i=) are derived and discussed numerically. It
