Abstract
Flexible antennas in radar applications enable the
user to go around obstacles or detect targets at hidden places.
In this paper, two elliptical lenses of different size made of
high density polyethylene and stacked on a flexible dielectric
waveguide are designed and measured from 140 GHz to 180 GHz.
The feeding dielectric waveguide and the mode transition from
metallic waveguide to dielectric waveguide was investigated with
full wave simulations. The elliptical lenses were designed with a
geometrical optics approach. The realized antennas have a gain
larger than 24 dBi and 27 dBi and a maximum side lobe level
below −15.8 dB.
