This letter studies the frequency- and time-domain performance of a recently developed printed coplanar-fed ultrawideband (UWB) monopole antenna aiming at predicting its behavior close to a human arm. The input reflection coefficient <formula formulatype="inline"><tex Notation="TeX">$(\vert{ S}_{11}\vert)$</tex></formula> and fidelity factor of the antenna were evaluated in free space and close to an arm. Simulations using three simplified arm models with different cross sections (flat… CONTINUE READING
