Wideband Mobile Antenna Design Using a Resonant Feeding Structure [PDF]
Parallel loop feed structures can be used to implement wideband impedance. However, when a parallel loop feed structure is employed, parasitic resonance occurs in certain feed structures, resulting in the degradation of radiation efficiency.
