METHODS OF REDUCING PATCH
ANTENNA
1. High Permittivity Substrate
2. Folded Patch
3. Shorting Pin
4. Slot Loaded Ground Plane
5. Slot Loaded Patch
6
BEST SOLUTION-SLOT LOADED PATCH
1. High Permittivity Substrate:
 reduced BW, increased dielectric losses, increased cost
2. Folded Patch:
 increased volume, complex manufacturing process
3. Shorting Pin:
 problems with radiation pattern, feeding and manufacturing
tolerances
4. Slot Loaded Ground Plane:
 problems with back radiation, less transmission power
5. Slot Loaded Patch:
can produce wide range of designs:
Reduced Size Single Frequency, Dual Frequency, Wideband

ANTENNA DESIGN
REFERENCE ANTENNA
L=29.4mm, W=30 mm, єr=2.33,
h=1.57 mm
Performance characteristics
• Return loss of reference antenna : -12.89
•Resonant frequency : 3.202
OUR
PROPOSED
DESIGNS
PROPOSED DESIGN: 1
Antenna with two equal slits on width side
SIMULATION AND PRACTICAL RESULTS OF
DESIGN 1
Performance Characteristics
Due to increase in slit length following changes occur :
• Resonant frequency increases.
•Bandwidth also increases.
•Antenna efficiency & radiation efficiency increases.
•Gain increases .
Microstrip rectangular patch antenna
PROPOSED DESIGN: 2
Antenna with three equal slits on width side and length side
SIMULATION AND PRACTICAL RESULTS OF
DESIGN 2
Performance Characteristics
Due to increase in width following changes occurs:
•Resonant frequency decreases.
• Return loss increases.
•Bandwidth decreases
•Antenna efficiency increases.
•Gain increases.
TOTAL DESIGN GAIN (dbi)
PROPOSED DESIGN :3
Antenna with four equal slits on length side
SIMULATION AND PRACTICAL RESULTS OF
DESIGN 3
Performance characteristics
Due to increase in length of slits following changes occur:
•Resonant frequency decreases.
•Bandwidth decreases.
•Antenna efficiency abruptly increases when length is 3mm & width is 2 mm.
TOTAL GAIN (dbi)
RESULTS
According to given equation frequency is inversely
proportional to length.
• In our first proposed antenna , frequency increases and to
decrease it we have to increase the length of antenna .
• In our second proposed antenna, frequency decreases and we
have decrease the size of antenna to increase the frequency.
• In our third proposed antenna we observed that there is
tremendous decrease in resonant frequency where as there is
steep increase in antenna efficiency .So to increase frequency
we have to reduce the size of antenna .
CONCLUSION
Focus on operating frequency to reduce the
size of patch is investigated . From the above
findings it is concluded that around 7-8 %
size reduction is possible, and no impedance
matching network is required for the size
reduction of proposed antenna .

  • 7. GEOMETRY OF ANTENNA Top view Side view PERFORMANCE CHARACTERISTICS: 1. Return loss 2. Band width 3. Resonant frequency 4. Antenna efficiency 5. Radiation efficiency 6. Gain
  • 8. ANTENNA DESIGN REFERENCE ANTENNA L=29.4mm, W=30 mm, єr=2.33, h=1.57 mm Performance characteristics • Return loss of reference antenna : -12.89 •Resonant frequency : 3.202
  • 10. PROPOSED DESIGN: 1 Antenna with two equal slits on width side
  • 11. SIMULATION AND PRACTICAL RESULTS OF DESIGN 1 Performance Characteristics Due to increase in slit length following changes occur : • Resonant frequency increases. •Bandwidth also increases. •Antenna efficiency & radiation efficiency increases. •Gain increases .
  • 13. PROPOSED DESIGN: 2 Antenna with three equal slits on width side and length side
  • 14. SIMULATION AND PRACTICAL RESULTS OF DESIGN 2 Performance Characteristics Due to increase in width following changes occurs: •Resonant frequency decreases. • Return loss increases. •Bandwidth decreases •Antenna efficiency increases. •Gain increases.
  • 16. PROPOSED DESIGN :3 Antenna with four equal slits on length side
  • 17. SIMULATION AND PRACTICAL RESULTS OF DESIGN 3 Performance characteristics Due to increase in length of slits following changes occur: •Resonant frequency decreases. •Bandwidth decreases. •Antenna efficiency abruptly increases when length is 3mm & width is 2 mm.
  • 19. RESULTS According to given equation frequency is inversely proportional to length. • In our first proposed antenna , frequency increases and to decrease it we have to increase the length of antenna . • In our second proposed antenna, frequency decreases and we have decrease the size of antenna to increase the frequency. • In our third proposed antenna we observed that there is tremendous decrease in resonant frequency where as there is steep increase in antenna efficiency .So to increase frequency we have to reduce the size of antenna .
  • 20. CONCLUSION Focus on operating frequency to reduce the size of patch is investigated . From the above findings it is concluded that around 7-8 % size reduction is possible, and no impedance matching network is required for the size reduction of proposed antenna .
