Abstract
This paper presents the design and measurements of a
beam-switching lens antenna at 60 GHz. The extended
hemispherical Teflon lens has a diameter of 20 mm and is
fed using a slot-coupled CPW-fed patch antenna on LTCC.
The S-parameters measured on a probe station are
presented. A V-connector was used to provide the
millimetre-wave signal connection to the feed antenna in
the radiation pattern measurements. A plastic support
made from PVC was fabricated to support the lens. The
simulated and measured radiation patterns of the feed and
the lens are shown. The maximum gain of 19.5 dBi was
measured for the lens antenna. A beam steering range of
56° was demonstrated by manually shifting the lens
position by 13.5 mm relative to the feeding antenna. The
presented design is a good alternative to a phased array
for a beam-steerable moderate-gain antenna for the
gigabit data rate wireless indoor applications.
