This work proposes a four element Substrate Integrated Waveguide based Cavity Backed (CBSIW) antenna. It introduces a novel CBSIW antenna design incorporating bow-tie shaped slots coupled with a quarter-wave power divider for the first time. The power efficiency and gain of the CBSIW antenna can be improved by combining low loss SIW cavities with a transmission line power divider based on a quarter wave transformer. A slot with bow-tie shape is etched on a square shaped SIW cavity with most favorable dimensions to construct the elements of the array. To achieve good impedance matching and proper power distribution to each element, the excitation is developed with a couple of T-shaped quarter wave power dividers connected end-to-end. The innovative combination significantly enhances gain (21.9 dBi) and efficiency (82%), outperforming existing designs and offering a unique solution for high-performance microwave and millimeter-wave applications. The experimental results are well matched with the simulation results produced by the HFSS software. [ABSTRACT FROM AUTHOR] |
