Low- Profile, Microstrip-Fed Slot Antenna for NR77/78 5G and WiMAX Applications

A novel VI slot microstrip-fed antenna is designed for NR 77/78 5G and WiMAX application for wireless operation. The innovation of the proposed antenna is the comprehensible structure which does not use any reactive elements, costly substrate, supplementary hardware and 3D structures. The proposed structure has designed footprint of only 18 × 8.8 × 1.6 mm³ and engraved on FR-4 substrate having relative permittivity 4.3 and loss tangent 0.025. Moreover, microstrip fed results in single resonance of (3.06-4.16 GHz) with simulated impedance bandwidth of 33.3%. The omnidirectional 2D pattern followed by gain of around 1dBi and efficiency values of approx. 60%, exemplify the pertinency of the antenna for wireless operation.
