Abstract

This paper presents a new SIW horn antenna with high performance in the mm-wave bands for the next generation mobile devices. The proposed antenna is integrated in a double layer of Rogers RO4003C substrate and requires a clearance of only 3 mm. Air vias are etched in the substrate in a specific portion of the horn aperture, in order to correct the phase of the electromagnetic wave and allow the beam pointing in the desired direction. Moreover, a tapered ladder transition is placed at the horn aperture to improve the impedance matching and enhance the radiation performance. Simulation results prove that the 6 dB bandwidth is wider than 40 GHz in the frequency range 24 − 64 GHz. In particular, the same beam pointing is guaranteed over the whole bandwidth with realized gain of 6.4, 8.5 and 8.7 dBi at 28, 38 and 60 GHz respectively. Simulations including two symmetric elements pointing opposite directions and a central element show that the angle of 90° can be covered with peak gain of 7.5 dBi at 28 GHz.
