Abstract: (1894 Views)
In this paper, a new wideband horn antenna based on the substrate integrated waveguide (SIW) technology fed by GCPW structure with compact size(3.38λ0*2.65λ0*0.14λ0) is designed. The proposed antenna is fabricated by using two Rogers RT 6002 with the same height of 1.524mm (total thickness of 0.14λ0 at the center frequency) and εr=2.94. The proposed antenna utilizes a suitable wideband transition in the feed section and an arc-shaped metal taper printed on the extended dielectric slab with two metal posts in the horn section. By using the proposed antenna, a wide impedance bandwidth without using ridged structures is obtained. The designed antenna has a VSWR less than 2.5 across a broad frequency range 8-19.5 GHz and show acceptable and stable radiation patterns in the same frequency range.
