This letter presents a novel dual-polarized dualwideband array design methodology based on radiator structure reuse, achieving dual-wideband impedance matching (VSWR < 2) over 0.69-1.3 GHz and 1.4–2.8 ...

An optimized zero-index metamaterial (ZIM) structure is proposed to enhance the gain of a planar Quasi-Yagi antenna in the X-band, addressing the impedance mismatch issues commonly encountered in ...
