Slotted Antipodal Vivaldi Antenna for Multiple Ultra-Wide Band Applications Including IoT
An Ultra-Wide Band (UWB) Antipodal Vivaldi Antenna (AVA) is intended proposed to serve a diversity of applications in the microwave and millimeter-wave bands such as Internet of Things (IoT) enabled by the fifth-generation communication (5G) applications, biomedical imaging applications and radar applications. The design is developed based on adjusting the radiating flares of a narrow slot antenna by cutting six rectangular slots on both flares' (top and bottom patches) sides. The non-uniform slot on the radiating patches is shown to increase the electrical length and create high- directivity radiation by downregulating induced surface currents that radiate vertically at the outer parts of the radiating arms into the end-fire direction. The proposed AVA has an ultra-wide operating band ranging from 3.29 GHz to more than 45 GHz. The simulated design has a size of 70.5 × 37 × 1.5 mm3. The results demonstrate good radiation patterns with gain of 7.7-11 dBi in the end fire direction. The obtained reflection coefficient results, without slits, exhibit an isolation between adjacent resonances in the mm-wave bands that supports IoT applications.
