Passive Millimeterwave Imaging (PMI) Technology is used to
view scene in foggy air conditions or to see concealed weapon under clothes
that cannot be seen other technology because of the materials of weapon. There
are some frequency windows to work with millimeterwave technology as 35, 96 and
220 GHz and it is near 35 GHz frequency for this work. Antenna is one of the
most important part in PMI Technology, consequently; major importance has been
given to this segment. Antipodal Vivaldi Antenna has 50.07 ohm input impedance
for matching to the forward circuit, and -39.23 dB input reflection
coefficient, S11, and 6.82 dB gain, is designed for 35.18 GHz in
Computer Simulation Technology Studio Suite Program (CST). After the antenna is connected to the other
circuits such as amplifier or detector, the created system will be integrated
into a scanner which is capable of scanning azimuth and elevation axes. As a
result, PMI System will be formed and ready to view the scene or the hidden
things in haze air conditions.
