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

摘要

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 mu-biological Near-Field Microwave Reduction Applications.
