This work investigates the use of substrate integrated waveguide fed open slot antenna (WOSA) in an array for the first time to provide a new SIW slot antenna array with wide bandwidth and single-layer structure. The antenna array consists of 4×2 substrate integrated WOSA elements as a radiating part and two 1-to-4 SIW power dividers as the feeding network. The whole array is d... https://www.intcariuma.shop/product-category/shoe-care/
