Data and Stuff for the Antenna: Antenna may be made
from a copper wire in diameter 1.8- 2.2- mm (11- 14 AWG). Perimeter
of the hat (it may be circular or polygon) is 234- mm. Vertical
two wire line has length 62- mm, distance
between the wires is 20-mm. One of the wire of the line is grounded
another wire is connected to the central core of the 50-Ohm coaxial
cable. Braid of the coaxial cable is grounded.
a ground it may be served a copper disk in diameter not less 320-mm
or 3 counterpoises in length of 168- mm radially connected to
a small disk (base of the antenna)
in diameter of 30- 50- mm .
of the ground may be decreased if the gap between the ground and
metal auto body is a small.
example here is shown a prototype of the Antenna “Shaiba”- lambda/4 stub Antenna. Figure 6 shows design of the antenna. Figure 7 shows Z of
the lambda/4 stub Antenna. Figure 8 shows DD of the lambda/4 stub Antenna. . File
