A substrate integrated waveguide (SIW) leaky-wave antenna (LWA) array with beam-formed radiation pattern is investigated in this paper. The array is composed of two LWA elements with different parameters of slots. For each LWA. the period of slots is selected first within the scope of only n = -1 space harmonic radiation to ensure the beam radiate in the desired direction. https://fitnessgravesyardes.shop/product-category/cable-20-pin/
