We were involved in ensuring that the antenna designed is
resonating primarily in two major frequency regions, 2.5Ghz
and 5Ghz, although it is a multiband antenna, but its most
distinctive characteristics were showcased in these two regions
which are known as S and C band frequency bands.

II. DESIGN OF ANTENNA UNDER STUDY

The basic scheme for implementing the design of rectangular

microstrip patch antenna is to find out the two most important
parameters in the dimensional domain (length and width).
We calculate the length of the antenna using the following
equations:

M= (N+1)/2 + (N-1)/2 * [1 + 12 A/B] 3/2

M= Dielectric constant (effective)

The measurements of the microstrip patch, substrate and the

feed line elements are illustrated through the following table.

VSWR:
The stricture VSWR is a degree that statistically designates
how well the antenna is executing impedance matching to the
broadcast line it is associated with.

Fig. 9: Total Gain

Apart from the total gain and directivity, another parameter

called radiation pattern is also determined. Radiation pattern
can be defined as a function of gain in terms of direction.
