Abstract:
The design procedure for a switching beam antenna
for wireless communication systems is given. The antenna can rotate
the beam over the whole azimuthal angle exploiting its geometrical
and electrical cylindrical symmetry. The required directivity
and the beam rotation are provided by a sequential insertion of
metallic posts into the radial waveguide that forms the main body
of the antenna. The first stage of the design involves setting up the
dimensions of an omnidirectional antenna, to which the desired
directivity is subsequently provided. After optimization to maximize
the impedance bandwidth, the final antenna was prototyped.
A comparison between simulated results and experimental data is
presented.
