Ultra‐directive palm tree Vivaldi antenna with 3D substrate lens for μ‐biological near‐field microwave reduction applications

We present a new Palm Tree Antipodal Vivaldi Antenna with an Exponential Slot Edge and 3D polylactide‐printed Substrate Lens presents an unprecedented directive radiation pattern, and simultaneously mitigates the side lobe level, increases the main lobe gain, and reduces the angular width, for μ‐bio...
