Micro Strip Line Design
It is advantageous to use the Micro Strip Line in high-
frequency transmission circuits because a low-loss trans-
mission can be achieved with this method. By etching the
dielectric base which has copper foil attached to both sides,
the Micro Strip Line will have a concentrated electric field
between the lines and ground, as shown in the following
diagram.

Dielectric base
(dielectric constant:

The characteristic impedance of the lines Z
O
is determined
by the kind of base (dielectric constant), the base’s thickness,
and the width of the lines, as expressed in the following
equation.

W: Line width

H: Dielectric base thickness
The copper foil thickness must be less than H.
The following graph shows this relationship.

For example, when creating 50-
lines using a glass epoxy
base with a thickness of 1.6 mm, the above graph will yield a
w/h ratio of 1.7 for a dielectric constant of 4.8. Since the base
thickness is 1.6 mm, the width will be h
×
1.7
≈
2.7 mm.
The thickness of the copper foil “t” is ignored in this design
method, but it must be considered because large errors will
occur in extreme cases such as a foil thickness of t
≈
w.
In addition, with the Micro Strip Line design, the lines are too
short for the G6Y’s intended frequency bandwidths, so we
can ignore conductive losses and the line’s attenuation
constant.
The spacing of the Strip Lines and ground pattern should be
comparable to the width of the Strip Lines.
