INTRODUCTION
APPLICATIONS
Antennas are devices used to transmit or receive signals such as radio or television signals;
Patch antennas are small, high gain, easy to fabricate, low cost, and high efficiency antennas
Military
GPS Navigation
Mobile and Satellite Communication
Radar
Telemedicine

CONCLUSION
REFERENCES
-The smallest change in measurement can greatly alter the results;
-It is possible to get similar measurements to the simulation if the fabrication is accurate;
-The measurements were very similar to the simulation because the dimensions were close to simulated ones.
