| Popis: | In this paper, a new slotted compact semi-open substrate integrated waveguide horn antenna is presented. The proposed antenna comprises three different sections namely; feeding, matching, and radiation sections. The feeding and radiation sections are matched within 13.6–25 GHz using an appropriate embedded slotted feeding structure. Also, best efforts have been made to achieve a more compact antenna in comparison with previous works. The experimental measurements of the fabricated antenna are in good agreement with simulation results. The fabricated antenna occupies 34 × 28 × 3.175 mm3 (2.1 λ0 × 1.93 λ0 × 0.19 λ0) where λ0 is the free space wavelength at 19.3 GHz. The proposed antenna provides a gain of 8.3–12.13 dBi together with 59% relative impedance bandwidth. |
