Millimeter-wave Substrate Integrated Waveguide (SIW) technology presents itself
as the most viable solution for the development of RF systems. It is a cost-e ective
solution, suitable for mass production of such systems. Like planar circuits, SIW
structures are compact, light weight and easy to fabricate. They also preserve some
of the major advantages of metallic waveguides, namely, low loss, high quality factor
and high power handling capabilities.
In RF systems, rectangular waveguide horns have found various applications due
to their exceptional radiation properties. From their simple construction, ease of ex-
citation, usefulness and high gain, they are readily used as feed component in various
RF systems, they also aid as the standardization for calibration and gain measure-
ments of other high gain antennas. We are aware that, in an H-plane horn antenna,
the rectangular waveguide is flared in the direction of the H-field. A large aperture
in the H-plane presents the narrower half power beamwidth whereas a small aperture
in the E-plane gives a wider beamwidth. In this research, the design of a SIW H-
plane horn antenna with approximately symmetric half power beamwidths in both the
E- and H-planes is proposed, using the commercially available electromagnetic field
solver CST Microwave Studio to design and simulate proposed antenna characteristics
and performance. Also, radiation patterns are analyzed and in order to validate the
simulation results, measurements are performed on a fabricated prototype antenna. / Graduate
