Amit Kirti Saran and Ramit Kirti Saran presented a design for a microstrip patch antenna at 2.45GHz. They described the basic structure of a microstrip patch antenna and the design equations used to calculate the patch dimensions. They then outlined the steps taken to design the patch antenna using HFSS software, including assigning the calculated values and adding an inset feed. Simulation results showed the radiation patterns and return loss of the designed antenna. Applications of microstrip patch antennas include mobile/satellite communication, GPS, Bluetooth, and medical and radar uses.

4. MICROSTRIP PATCH ANTENNA
 Microstrip patch antenna consists of a conducting patch and
ground plane between them is a dielectric medium called the
substrate
 The dimensions of a patch are smaller as compared to the
substrate and ground
 Microstrip patch antenna depend on the resonant frequency and
value of the dielectric constant
 Microstrip patch antennas radiate primarily because of the
fringing fields between the Patch edge and the ground plane

5. DESIGN EQUATIONS
 Step 1: Calculation of the Width (W):
 The width of the Microstrip patch antenna is given as:
Substituting c = 3.00e+008 m/s, εr = 2.45 and fo = 2.4 GHz
W = 0.0475 m = 47.5 mm.
 Step 2: Calculation of Effective dielectric constant (εreff):
 The effective dielectric constant is: Substituting εr = 2.45, W = 47.5 mm and h
= 1.58 mm
εreff = 2.3368

6.  Step 3: Calculation of the Effective length ( Leff):
 The effective length is:
Substituting εreff = 2.3368, c = 3.00e+008 m/s and fo =2.45 GHz
Leff = 0.0406 m = 40.625 mm
 Step 4: Calculation of the length extension (L):
 The length extension is: d Substituting εreff = 2.3668, W = 47.5 mm and h =
1.58 mm
 L = 0.81 mm

7.  Step 5: Calculation of actual length of patch (L):
 The actual length is obtained by:
L = Leff - 2L
Substituting Leff = 40.625 mm and .L = 0.81 mm
L = 39 m = 39 mm
