Novel Approach for Designing Broadband Slot Antennas
MetadataShow full item record
This paper presents a novel approach for designing broadband slot antennas. The proposed technique involves gradually incrementing the slot length along the propagation direction in order to provide a smoother impedance transition between the waveguide and air. Numerical and experimental results demonstrate up to 52.3% of bandwidth improvement by employing our approach in slotted-waveguide antenna arrays. The technique presents itself as a promising solution for 5G enhanced mobile broadband (eMBB) communications.
