Parallel resonance feed structures can be used to implement wideband impedance characteristics. However, at some frequencies, parasitic resonance is generated in the feed structure. Radiation efficiency nullification occurs at the frequency of the pa

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. This is
