This slide describes design and simulation about the micro strip patch antenna using HFSS software.study the return characteristics,gain(db)and radiation pattern As the given frequency & substrate thickness, we calculate substrate length,width & patch length.you can refer theory in "ANTENNA THEORY" by C.A.Balanis

Reg no:16MCE0036

2. Aim
• The aim of the thesis is to design and fabricate
an inset-fed rectangular Microstrip Patch
Antenna and study the effect of antenna
dimensions Length (L) , Width (W) and
substrate parameters relative Dielectric
constant (εr), substrate thickness (t) on the
Radiation parameters of Bandwidth and
Beam-width.

3. Technical objective
• There are several important antenna
characteristics that should be considered
when choosing an antenna for your
application as follows:
1).Antenna radiation patterns
2).Gain
3). Directivity

4. Design
• The three essential
parameters for the design of
a rectangular Microstrip
Patch Antenna
• Frequency of operation
(fo)=3.3GHZ
• Dielectric constant of the
substrate (εr)=2.94
• Height of dielectric substrate
(h)=1.6mm

5. Design procedure

7. Simulation
Designed for 2.4 GHz operation on a
substrate with 1.6 mm thickness.
