Abstract

This paper presents a new wideband Substrate Integrated Waveguide -SIW- H-plane horn antenna. A few rows of diamond patches are printed on the top and bottom side of the dielectric slab at front of the radiating aperture of a conventional horn to improve impedance matching. The proposed antenna is numerically investigated using a software package and a prototype of the antenna is made to validate the obtained simulated results. The measured results show that the introduced antenna provides 22.7% impedance bandwidth, which covers from 20.8 GHz to 26.15 GHz with stable end-fire radiation patterns, while Side Lobe Level -SLL- is lower than 10 dB over the operating bandwidth.
