Egil Eide from NTNU in Trondheim, Norway visited us in September. Here are some images from experiments with his bowtie antenna.

construction of bowtie antenna
The antenna consists of a transmitting and a
receiving bowtie mounted on a common ground
plane. The purpose of the yellow absorbers is
two fold. First, they suppress back radiation
and second, the constitute a resistive loading
that increases the bandwidth of the antenna.
