Abstract: This letter presents a Ka-band circularly polarized (CP) ridge gap waveguide (RGW) antenna featuring wide axial-ratio (AR) bandwidth and good grating lobe suppression. A novel composite ...
This article explores the performance of a Yagi-Uda patch antenna with Koch fractal geometry of different orders on an FR-4 substrate. It exhibits multiband operation, enabling the use across multiple ...
