Efficiency enhancement of wideband mobile antenna

초록

A resonant feeding loop is used to obtain the desired wideband impedance characteristic. Two implementations are presented and their efficiency characteristics are compared: a low-admittance resonant feeding loop and a high-admittance resonant feeding loop. Experimentally it is demonstrated that the low-admittance feeding loop provides better radiation efficiency than the high-admittance feeding resonant loop.
