The receiver is the easiest. The Antenna are available
to commercial. This idea is explored along with producing new antenna. As
you can see figures 3.1 and 3.2 connector to connect to the antenna. For
preliminary research Wave whip antenna is used for all the tests. This
antenna is similar to that used on the car radio. A quarter wave antenna. It is
designed to provide length. About one quarter of the wavelength of the signal. This
means that the 915MHz signals with a wavelength of 32 cm quarter-wave antenna will
have a length of 8 cm butcher in using this type of antenna. It wants
large aircraft instead of ground to make work properly. Well, the car radio can be
grounded to the frame, but the ground plane is necessary to get
enough signal energy charging circuit is larger than the form factor of the charging
circuit in the home stands. Shows a wave coming from the whip antenna
