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 x 28 x 3.175 mm(3) (2.1 lambda(0) x 1.93 lambda(0) x 0.19 lambda(0)) where 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.
