Current and field distribution of the proposed \({\text {T}}_{\text {x}}\) and \({\text {R}}_{\text {x}}\) antenna at its resonant frequency of 1.5 GHz. (a) Behavior of the current distribution on ground and patch of the \({\text {R}}_{\text {x}}\) antenna. (b) Field distribution when \({\text {T}}_{\text {x}}\) antenna in flat and bent states. (c) Field focusing efficiency of \({\text {T}}_{\text {x}}\) antenna in the flat and bent states. (d) Impact on \({\text {S}}_{\text {21}}\) when \({\text {T}}_{\text {x}}\) in flat and bent states.
